Dr. Bruno Fazenda graduated with a PhD in Room Acoustics and Psychoacoustics from the University of Salford, UK, where he was funded by the Portuguese Ministry of Science. He worked as a Research Fellow with a Marie Curie research fellowship at the Danish Technical University before becoming a lecturer in the UK.
Dr. Fazenda has been employed as a Senior Lecturer at the University of Huddersfield since September 2006 and lectures in subjects of music technology and acoustics. Since arriving at Huddersfield he has been extensively engaged in research. Within 3 years he has formed a working group researching areas of sound quality and has helped the Music Technology Research Group to grow from 1 to 4 researchers. Dr. Fazenda has successfully secured and currently manages funding for his PhD students.
His research in room acoustics has led in the area of accurate reproduction and perception of sound in rooms, looking particularly at problems affecting rooms at low frequencies. These are considered to be one of the main causes for problems in critical listening spaces and account for the large differences between facilities, which has undermined their efficiency as state of the art audio production studios. The type of activity involved in this research topic ranges from analytical modelling of spaces, the development of analytical solutions for different methods of low frequency excitation, case studies on the use of low frequency absorption in rooms and commissioning psychoacoustic testing to define thresholds of detection for a number of factors under study. Overall, the results from this work have a direct application on critical listening room design and modal control techniques. They are of utmost importance as they influence the design of rooms and advanced modal control techniques that afford better listening conditions.
Dr. Fazenda is part of a multidisciplinary research network studying ancient Neolithic monuments in Britain with the aim of revealing pre-historic activity in sites of international renown such as Stonehenge. This work is a collaborative network between departments at the University of Huddersfield, University of Sheffield, University of Leeds and Arup acoustics among others.
In 2007, Dr. Fazenda joined the Diagnostics Engineering Research Group at the University of Huddersfield as an associate member to work in areas of signal processing and sensor technology. Within this group he has been involved in projects for diagnostics of engine transmission belts, leak detection in turbo-charger systems and the localisation and classification of noises inside car cabins. He has sought direct application of these ideas into industrial applications and successfully secured funding to collaborate with industrial partners, which he currently manages.
During this time, he has been developing an independent research agenda focused on systems for detection and warning of dangers based on psychoacoustics and hearing, sensor technology and signal processing which he is now pursuing to establish a novel area of research.
Dr. Fazenda is a member of the review board for international publications such as the International Journal of Vehicular Technology and the Built Environment (published in Brazil). He is a member of the Audio Engineering Society and the UK Institute of Acoustics and has recently applied for a Fellowship in Higher Education.
Main research interests are in the areas of acoustics and acoustic sensing, psychoacoustics, room acoustics, perceptual aspects of sound reproduction and sound quality. I am also interested in aspects of human safety and welfare through machine enhanced awareness leading to the development of novel warning systems both for personal use as well as for vehicles and infrastructure.
I am currently working with industrial partners on a number of projects which include: the development of a variable low frequency absorber for critical listening spaces; a sound localisation probe for detection of noises in car cabins; and the integration of subwoofers and satellite speakers in surround sound systems.
