Part of MARC's research is the undertaking of research projects registered in the CEP (Central Register of Projects of the Government Council for Research and Development), the list of projects is sorted in ascending order (from oldest to newest):
Abstract: The project is a platform for scientific cooperation, which will use the services of the e-infrastructure, CESNET (especially the results of previous projects FRC 384/2010, 423/2011, 465/2012, 552R1/2014 and 632/2018) for multidisciplinary communication and cooperation of experts on voice issues, and to supplement the possibilities of the existing web application PsychotestEditor with the necessary safety and training elements for teaching and research with a focus on perceptual evaluation and clinical examinations of the voice. The aim is to set up a professional group of specialists covering the range of issues of vocology with their professions and to create its connectivity. In addition to the use of technologies for mutual communication in the form of multidisciplinary seminars, specific, clinical, distance-examinations are also ready for practical testing in work and teaching contexts. At the same time, work will be carried out to improve the web application, PsychotestEditor, which can create perception tests for specific use in teaching and research. This is done according to specific proposals compiled by a professional group of specialists. Due to the nature of the planned use, the application will be supplemented with security features, authentication and authorization of systems to allow work with confidential and clinical data.
Abstract: The project builds on the IP DKR project "Sound Quality" and continues to address the causal relationships between physical (objective) and perceived (subjective) properties of sound and their relationship to quality. Sound quality is examined in speech and singing vocal expressions as well as in the sounds of musical instruments. The project is mainly focused on basic research, as other grants addressed at MARC have the character of applied research, as requested in submissions by external providers. The focus builds on basic research from the previous projects: 1M Research Centre for Music Acoustics (2005-11), DKR Sound Quality (2014–18), and DKR Organs and Their Sound (2016–17). Objective and subjective properties of vocal expressions and sounds of musical instruments which students generally perceive as pleasant are studied. The aim is also the determination and psychoacoustic measurement of those properties of sound which determine that listeners label them as being of quality (for sounds produced for a specific purpose). For musical instruments, it is the colour of the tone. Voice research deals with the vibroacoustic properties of vocal cords and adjacent resonant parts, and their connection with subjective descriptions of sound properties as perceived by the listener. (It is also aimed at the artistic use of the voice and the emotional effects of the sound of music on listeners).
Abstract: The project followed on from the projects FRC 552R1/ 2014 and 465/2012, where the web application PsychotestEditor for psycho-physical tests was created (programmed in a domain-specific language, which allows the preparation of perception tests with acoustic, image and video stimuli). Based on previous experience of its use in the teaching of speech therapists or in the field of phoniatrics and ENT (training in evaluation of voice disorders, evaluation of gross motor problems and laryngeal mobility with control of answers, etc.) the aim was to enrich the functionality of the application created for scientific and educational activities, for use also in new technological areas, including machine learning. Thus, there was an extension to include other, specific types of assessment and the possibility of presenting these results in the teaching context (this concerns the interactive determination of the position or contours of objects of interest, or trajectories of movement of monitored objects and events in the image, for video-sequential stimuli). Specific forms for entering stimuli data were also added, connected to the relation to end-user databases. The project also measured specific educational data (audio and video recordings) to create a MARC database simulating publicly inaccessible databases of clinical workplaces.
Abstract: The project is undertaken by CESNET z.s.p.o. and MARC, HAMU. The goals of the project include the construction of a model workplace for distance learning and cooperation in culture (in the performing arts on the premises of HAMU). The project will create and make available modern technical means enabling a new way of undertaking tasks, in the education of students and in the mentoring of art teachers. CESNET is developing a prototype device for low-latency audio and video transmissions enabling distance learning and collaboration in the performing arts. MARC experimentally verifies the use of these new technical means in art education (in new types of distance cooperation, interactive distance courses and distance evaluation of artistic performances). As a result of knowledge from experimentally verified types of education, the methodology for their use is elaborated. As part of the project, a world conference/workshop, "Network Performing Arts Production Workshop", was organised at HAMU (NPAPW 2019, which now takes place every year alternately on the American continent and in Europe and deals with technologies and methods enabling the use of remote internet connection in the arts). Three procedures were presented at HAMU, which try to minimize the delay of the transmitted image and sound so that the participants in the telebridge can cooperate as if they were meeting in person. Of these, on presentation, the new low-latency MVP technology developed by CESNET (in cooperation with MARC), involving mutual, audiovisual communication of the highest 4K quality, with a delay of only a few milliseconds, allowing musicians to play synchronously even when in various buildings and locations, proved to be the best. Due to the high sensitivity of the artistic performance to external conditions, the results of the practical verification of this MVP technology implemented at MARC were presented by MARC staff in lectures and a workshop at a conference. They successfully tested its use in distance teaching between partner institutions HAMU and DAMU and at public concerts (e.g when used in the rhythmically-demanding music of Bohuslav Martinů or during the Czech, joint concert project, "Resisted Evil" on the occasion of the Václav Havel Prize for Human Rights in cooperation with the Václav Havel Library). Part of the NPAPW 2019 conference was also an artistic, public music and dance performance, "I Wish to Dance Well Under the Stars" realised with the help of MVP for audiences in Prague and Barcelona, where a musical composition was presented synchronously played on three organs (from the Martinů hall at HAMU and two Prague churches) accompanied by a real time dance performance by two dancers located in Prague and Barcelona respectively. (Due to the Covid-19 situation, this technology for the future constitutes a visionary act in the development of new teaching methods). All these experimental performances were a success, and therefore the researchers of the project (jointly CESNET and HAMU), together with other international broadcasts tested were entered for the competition for the European Prize for Cultural Heritage EUROPA NOSTRA (Cross-Border Cooperation for a European Classical Music Project). The entry submitted subsequently won the highest European award, EUROPA NOSTRA 2020 (the distance cooperation referred to thus ranked among the 21 most outstanding achievements of all the applications from 15 EU countries).
Abstract: The project is undertaken by Alternetivo s.r.o., CESNET z.s.p.o., LETEL elektronik s.r.o. and the Academy of Performing Arts in Prague (MARC, HAMU). The aim of the project is to develop a new method with elements of the Internet of Things (IoT) for applications in the field of monitoring sensitive objects (monitoring of temperature, humidity, pressure, the force of acceleration, tilting, etc). The method developed is to serve in many areas and have a global impact. The project's objectives include the verification of new elements in the national pilot operation, the provision of a production license and the preparation of results for placing on the market. MARC is cooperating in the development of a mobile sensor (use, for example, in the transport, placement or handling of musical instruments), and facilitates research into and development of a functional sample of a stationary sensor for use in the organ, including experimental verification of the sensor on a national scale in the framework of the nationwide, Czech Organ Foundation (Varhanní fond ČR).
Project DG18P02OVV014: "The Historical Organ, the Means for its Sound Preservation and Restoration and Comprehensive Musical, Acoustic and Monuments Research, as Part of the National Identity and Cultural Heritage in the Czech Republic"
Abstract: The project is undertaken by MARC, HAMU with NPÚ. The global goal of the project is the preservation, systematic rescue and reconversion of the artistic and sound wealth of the national collection of historical organs. To achieve this aim, there are specific goals that address the most important research accounts related to the above issues in accordance with the objectives of the NAKI programme:
1. research and development of: a) working procedures and materials for protection, restoration and improvement of the care system preserving the sound form of the historic organ, b) means for monitoring and recording factors influencing the condition of the organ, c) non-destructive methods of technology diagnostics for those organ parts, d) means for the documentation, registration and protection of the most endangered organs dating from periods in history, which were not addressed by the project DF12P01OVV012 of the NAKI I programme;
2. optimization of the process of restoration of the historical organ and its care in terms of sound authenticity; the rescue of authentic sound attacked by a natural threat - the wood-destroying insect (and other procedures not addressed by the project DF12P01OVV012);
5. comparative research using data results from the project DF12P01OVV012 as well as results newly obtained in this project (applies to the whole of the Czech Republic, including all regions and minorities);
6. integration of the results of research on historical organs in the Czech Republic, into education, including presentation and access to results in the context of the national, regional and local identity of society and cultural heritage;
Abstract: The project addressed the issue of physical principles of the sound of organ pipes and the influence on perceived properties of sound by changes in the setting of the mouth (intonation adjustments of the lips). As HAMU does not provide permanent institutional resources for the operation of MARC, the competitive internal project, DK DKR, together with the project, "Sound Quality", was the second main source of funding for research work, so this enabled 1 employee who had been released from employment at the end of 2015 due to lack of funds for the said employee's wages, to be rehired. The project's aim was to gain new knowledge about the acoustics of the organ for those interested in the musical–artistic, organological and musical–listening public and to process it in the professional monograph, "The Sound of the Organ Whistle". The results obtained were also published in journals impacted, and the functional sample of a transparent organ pipe developed is also used in the follow-up project NAKI II (for all results see MARC Publication Results).
Abstract: The project created a new web application, PsychotestEditor, designed for psychoacoustic and psychophysical voice tests, which would be generally applicable for participants in the CESNET network in various workplaces with different specialisations. This was a follow-up to the results achieved in the FRC 465/2012 project, in which MARC prepared a basic, locally available application (it was available to the public in the form of remote access to the voicelab.cesnet.cz server, which was cancelled before the project began). At the same time, an educational project was prepared by 13 public universities called, “Connecting Voice Care and Teaching Future Voice Professionals”, which was submitted for the CZECH MINISTRY OF EDUCATION, YOUTH AND SPORT (MŠMT) programme and which gathered together the research requirements of a number of institutions: members of CESNET Prague, Charles University in Prague, Masaryk University in Brno, the University of Ostrava in Ostrava, Palacký University in Olomouc, the University of Pardubice, the University of Hradec Králové, the University of West Bohemia in Pilsen, the Technical University in Liberec, the University of South Bohemia in České Budějovice, the Institute of Chemical Technology in Prague and the Jan Evangelista Purkyně University in Ústí nad Labem). The programme was cancelled by the provider of the Ministry of Education, Youth and Sports (the whole project, administratively very demanding, was therefore neither evaluated nor accepted), but MARC began to explore some of the ideas collected within this project. For this reason, the supplementing of database recordings was introduced using new technical equipment; video recordings of laryngostroboscopic findings and body movements during breathing accompanying vocal expressions were realised, and added to existing recordings of pathological and non-pathological voice from previous FRC projects. This data is an important parameter of specific voice expressions and is ready for use in follow-up projects.
- THE CZECH MINISTRY OF EDUCATION, YOUTH AND SPORT (MŠMT) PROGRAMME FOR "LONG-TERM CONCEPTUAL DEVELOPMENT OF THE INSTITUTION"
Abstract: The project addressed the issue of qualitative connections of physical properties of sound sources with auditory perceptions of selected sound sources (the human voice, the sound of violins and wind instruments). As the operation of MARC, HAMU has no permanent institutional funding, its staff must compete for 100% funding of work in research projects. For 2016 and 2017, none of the many MARC projects prepared and submitted to competitions announced by external providers was accepted. In these years, therefore, the operation of the MARC Research Centre and the salaries of all its employees had to be fully paid from the internal project, IP DKR, entered to compete in 2013, within the Internal Competition, in the Long-Term Conceptual Development programme, (the financial support distributed in this competition is received by AMU from the provider, the MŠMT on the basis of RIV results, to which MARC makes a significant contribution). For these years, therefore, the research plans of the “Sound Quality” project had to be revised and its budget items adjusted, but even so, the number of MARC experts had to be reduced by 3, which significantly weakened the human resources of the HAMU research infrastructure (AMU). Despite this complication, even with a lack of resources to carry out scientific research experiments, all the planned key results were achieved. Students of HAMU and DAMU also became more involved in the project (there was an increase in quotas of doctoral students at the Department of Sound Design, KZT, with which MARC is directly related). The preparation of other projects began, using the results, and the latter’s internal use in teaching or lifelong learning courses significantly increased. Not until 2018 were a total of 3 other projects accepted by the provider (in the NAKI II, MIT - Trio, TAČR - Éta programmes of the Czech Ministry of Culture), which made it possible to pay from DKR in addition to wages. completely abolished in previous years. The project brought a number of scientific research results to the RIV (see the MARC, HAMU Publication Results website) and thus additional financial DKR funds for R&D at AMU.
- THE EU COMMISSION PROGRAMME, CONTRACT FOR COOPERATION ON RESEARCH: "MULTI-GIGABIT EUROPEAN RESEARCH AND EDUCATION NETWORK AND ASSOCIATED SERVICES"
Grant Agreement No. 605243, project GN3plus: "Using Géant Dynamic Circuits to Support Remote Collaboration in Musical Education and ECulture"
Abstract: The aim of GN3 + was to explore technical possibilities of two-way 10G transmissions for use in remote cooperation in the field of music education and electronic sharing of music culture in practice. Participants in the European cooperation: CESNET, z.s.p.o. (Czech Republic), Consortium GARR (Italy), JANET (United Kingdom), Academy of Performing Arts in Prague (Czech Republic), Conservatorio di Musica Giuseppe Tartini (Italy), Edinburgh Napier University (United Kingdom). MARC created a specialised, acoustically modified room at HAMU with equipment for remote audiovisual 10G transmissions. It tested the method of LoLa low-income software developed by GARR for the evaluation of distance analysis of a singer's vocal expression. It collaborated on an experiment in the art of teaching the violin. The practical results of the eCulture collaboration were presented at the 38th APAN 2014 meeting in Nantou (Taiwan), where jazz musicians in Prague (Czech Republic HAMU), dancers in Barcelona (Spain), a violinist in Miami (USA) and a dancer in Nantou (Taiwan) were audio-connected in a joint, artistic performance, "Dancing in the SpacE", as well as at a 2015 conference/workshop in London, where a 4k video and audio signal was transmitted in both directions during an experimental, joint performance, "Cyber Performance", by a HAMU violinist in Prague and a pianist at the Royal College of Music in London.
- A CESNET DEVELOPMENT FUND PROJECT (FRC)
Abstract: The main goal of the project was to build an infrastructure for the capacitive connection of HAMU workplaces to the 10Gbps CESNET backbone network for the purposes of Hi-Tech high-speed, audiovisual transmissions. Thanks to the infrastructure created, HAMU was successfully involved both formally and informally in international projects. The research goals followed on from projects 423 and 424/2011, and focused on the creation of measuring apparatus and procedures for measuring breathing movements during voice production and vocal cord oscillations, with high-speed pick-up and the playing of wind instruments (lip vibration analysis).
- A CESNET DEVELOPMENT FUND PROJECT (FRC)
Project No. 465/2012: "Interactive Research and Educational Psychoacoustic Analyses with a Focus on the Voice"
Abstract: The project addressed the infrastructure of virtual servers of the application "RealVoiceLab" and a web application for psychoacoustic, perceptual and psychophysical tests (extension of applications usable by the wider scientific and educational community). The primary results from both applications were prepared for implementation in a database for use in statistical and other follow-up research. The hardware management was transferred to the e-infrastructure provided by the CESNET association, and HAMU focused on research for the implementation of new web applications. During this period, methods of collecting optical data obtained using a high-speed camera with high resolution and a high number of frames per second (for vocal cords in connection with the laryngoscope), and the use of data storage in the CESNET network for this data, were mainly explored. Algorithms for processing optical data and tracking changes between individual images were also considered, creating appropriate characteristics that would correlate with the physical and perceived properties of sound. The results were published in articles (properties of the singing voice, evaluation of voice resonance and perceptual evaluation of the pathological voice).
Abstract: The project was undertaken by MARC, HAMU with NPÚ and concerned the application of musical acoustic and cultural-historical scientific research findings in practice in the field of protection, care, documentation and restoration of the national fund of historical organs as one group of the most endangered monuments. The main results included: scientifically validated methodological recommendations of conservation materials and technological procedures for the restoration of historic pipes with regard to their sound properties, a utility model of analysis equipment for documenting organ sound "in situ", a methodology for organ sound analysis "in situ" using developed analysis equipment, a utility model and methodology for use of equipment for monitoring the influence of temperature, humidity and operation on the condition of the organ, database documentation and records of the National Fund of Monumental Baroque organs, a manual for the work of organists, a legislative initiative to change the law on care of monuments and the introduction of a new category of monument with sound value, including adequate ways of protecting it.
Abstract: The project addressed the acoustic properties of the human voice in relation to the vibrational properties of the vocal cords monitored by optical methods (and the same for the sound of stringed musical instruments). In particular, these were methods of collecting optical data obtained using a high-speed camera with high resolution and a high number of frames per second (for vocal cords, in relation to a laryngoscope) and the use of data storage in the CESNET network for this data. Algorithms for processing optical data and tracking changes between individual images were also explored, creating appropriate characteristics that would correlate with the physical and perceived properties of sound. The results were published in articles (on vocal cords, strings, the lips of the musician on brass instruments).
- A CESNET DEVELOPMENT FUND PROJECT (FRC)
Abstract: The project developed an existing system (server and SW) for remote access to acoustic analysis of voice signals for end-users (members of the CESNET association). It developed the system by adding analytical tools of new one-dimensional data (sound and electroglottographic data).
Abstract: Within the framework of this project, long-term cooperation was established with the FRC involving the carrying out of research tasks using the infrastructure of the CESNET association, which institutionally supports this type of research in the FRC project competition. The basic goal of the project was to create an environment for remote access to acoustic voice analysis for members of the CESNET association, to use high-speed cameras to analyse the oscillations of musical instruments and vocal cords and to develop tools for analysing image data from high-speed cameras. For the analysis, a server with an application for remote access to voice analysis was created (it was used for a number of outputs - see articles) and high-speed cameras were tested (acquired from AMU for cooperation with clinical workplaces and to record vibrations of works and parts of musical instruments, in musical and psychological acoustics research in the HAMU Sound Studio in cooperation with manufacturers of musical instruments).Following the results of the implemented experiments, the development of two FRC projects, 423/2011 and 424/2011, was possible.
- THE CZECH MINISTRY OF EDUCATION, YOUTH AND SPORT (MŠMT) PROGRAMME, "NATIONAL RESEARCH AND DEVELOPMENT SUPPORT, RESEARCH CENTRES PP2-DP1", PROJECT 1M6138498401 "RESEARCH CENTRE OF MUSICAL ACOUSTICS"
Abstract: Within the framework of this project, the statutory status of the Research Centre of Musical Acoustics, MARC at HAMU was institutionally established (until then the research was undertaken in the research department of the Sound Studio HAMU). SONING Praha a.s., ORGANA s.r.o. became professional and economic partners of the MARC Research Centre. Kutná Hora and FEE CTU became a professional–ideological partner in the teaching of doctoral studies in the field of Acoustics. The subject of the research centre's activities was the acquisition of new scientific knowledge which, based on physical–acoustic measurements and psychoacoustic methods, expanded knowledge about the colour of classical musical instruments and the human voice. This could then be used as initial information for subsequent applied research and industrial development. The Cabinet of Voice and Speech Education of DAMU also collaborated on the research. The results are listed in MARC publications.
Abstract: Within the project of European cooperation, MARC, HAMU explored the methodology for subjective evaluation of the tone quality of innovated organ pipes, which would enable comparison with the corresponding historical patterns. The main researcher was Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung, Leonrodstrasse 54, D-80636 München, and the partner research institute was Abteilung IBP.2, Fraunhofer Institut für Bauphysik, Stuttgart. The methodology was used to evaluate technological innovations for a consortium of organ companies. The results obtained were subsequently used in the follow-up project of the ICRC of the NAKI programme.
- THE CZECH SCIENCE FOUNDATION (GACR) PROJECT
Abstract: The project was focused on basic research with the aim of finding the properties of the perceptual space of the colour of a musical sound. In addition to determining the number of dimensions of this space, words describing the impressions of students in the perception of its basic dimensions were identified. Generally shared descriptions of sound colour in words have been published (see MARC Publication Results) and are used in other psychoacoustic research.
- THE PROGRAMME, "TWO-WAY COOPERATION WITH SLOVAKIA"; MARC'S PARTNER RESEARCH DEPARTMENT WAS THE FACULTY OF WOOD AT THE TECHNICAL UNIVERSITY IN ZVOLEN.
Abstract: as a follow-up to the previous project 17, this project involved experimentally oriented research focused on the methodology for measuring violin and guitar records. The results have been used in conference papers and in functional samples (see MARC Publication Results).
Project 17 "Acoustic Properties of Musical Instruments and Physical-Acoustic Characteristics of Materials Used in Their Production"
Project 105: "Material Characteristics of Wood and Corresponding Acoustic Properties of Inherent Musical Instruments"
Abstract: The project used the results of the previous project VS 96031 and added to them the vibroacoustic characteristics of musical instruments with the properties of their sounds as perceived by the listeners. It focused on the perception of sound colour, which is a multidimensional, subjective phenomenon that comprehensively reflects the acoustic properties of musical signals produced by musical instruments in the listener's consciousness. The distinguishing acoustic properties of natural sources of musical signals were represented by individual elements of their typological network. The research was based on finding psychoacoustic quantities describing various aspects of sound colour perception,and their relationship to typological features. The descriptions of the colour of sound obtained were used as subjective identifiers of the source, and as the dominant qualitative indicators of its perceived properties. The colour-forming dimensions and verbal descriptions of the colour of sound obtained were published, and are further employed in all subsequent projects.
Abstract: The subjective evaluation of digital sound effects in terms of their perceptual and musically aesthetic effect in this project was specifically focused on the evaluation of artificial reverberation in stereo recordings of classical music.
Abstract: The project was focused on the creation of acoustic characteristics that would allow comprehensive documentation of the sound-vibration properties of classical musical instruments. The aim of the project was to research into a unified methodology for the analysis of these characteristics, leading to the design of a typological network of sound identification and classification of sources of musical signals. This typology was applied in practice in the proposal for the publication of an acoustic atlas of musical instruments in the form of a CD-ROM, conceived as an open system of documentation of their general and specific sound properties and data for vibro-acoustic research, connected with perceptual evaluation of sound in follow-up projects.
Abstract: The project was undertaken by VUZORT a.s. in cooperation with HAMU. The collaboration took place during the recording of violin sounds for stimuli used in listening tests with tones of different quality violins, in a non-reflective room (the violins were provided by HAMU artists). The HAMU sound studio (MARC) provided the respondents (musicians and music theorists) as well as the space for performing listening tests. The output achieved was qualitative expert knowledge about the frequency transmission characteristics of violins and verbal descriptions of the colour of violin tones (the results were compiled into a publication by the HAMU Publishing House).
Abstract: The project was undertaken by the University of Music in Vienna (IWK) together with VUZORT a.s. in cooperation with HAMU. The cooperation took place during the experimental gauging of the violin using a specialised exciter. The modified excitation system was used in MARC in the project GA CR No. 202/93/2522, the system developed is distributed by IWK under the name BIAS.
A Programme of the Ministry of Culture of the Czech Republic, "Research and Implementation of Progressive Methods and Technologies for the Rescue, Protection, Archiving and Presentation of Cultural Monuments and Works of Art"
Abstract: The project was undertaken by VUZORT a.s. in cooperation with HAMU. The collaboration took place with the participation of a musician at HAMU, who performed for the gauging of the organ in churches, at organological consultations and for the audio evaluation of sounds, results which were subsequently used to develop a basic documentation method using 3 microphones. Based on this cooperation, the VS 96031 project was prepared by the HAMU Sound Studio and submitted to the CZECH MINISTRY OF EDUCATION, YOUTH AND SPORT (MŠMT) programme, "Strengthening Research at Universities", which enabled researchers to switch to research at HAMU after the termination of VÚZORT. In MARC, this research was followed by NAKI projects.
