2/ Research Experience

My background is both Mechanical Engineering and Theoretical Physics; but I have experience with Architecture from the School of Architecture of the University of Auckland. Recent work on perception has been carried out in close collaboration with psycholinguists and psychocognitivists.

 

My research experience covers more particularly:

     Transducers - loudspeaker models. Initially, I developed OmniSource 4295 for Brel & Kjr in 1993. More recently, there have been demands from outside, leading to the establishment of a start-up company (Haliaetus Technologies) which did not survived the 2008 crisis.

     Room acoustics - measurements, and small scale simulation. It essentially concerns the development of the MIDAS system in collaboration with the University of Auckland and the Universit du Maine. To-day, a handful of consultants are still using MIDAS world wide. Several Ph.D. were devoted to various extensions of the system, such as "auralisation", or listening in the model. Recently, at the request of acoustical consultants, MIDAS was redeveloped as open software.

MIDAS allowed several measurement campaigns in concert halls and theatres. A recent PhD candidate measured 16 Parisian halls, including with the public. It gave the laboratory an excellent reputation among theatre directors. Research continues with another PhD candidate who, in addition to measuring a few more halls, has simulated them in the laboratory listening room.

     Sound fields – modelling. At first, the worked aimed at modelling modes and reverberation through the ergodic theory of abstract dynamical systems, in order to justify the use of ray tracing in room acoustics on a theoretical basis. It evolved toward understanding how a diffuse random field, reverberation, gradually settles up in a room, and how at low frequency, an organised structure, the eigenmodes, emerges from the reverberant field. In a PhD in 2009, we attempted to measure the establishment time of the diffuse field, only to discover what we do not measure the establishment time of mixing, much longer. We therefore looked back at the diffusion equation, which presently enjoys a resurgence of interest, and expand it to the conservation of the stress-energy tensor, well-known in relativity. This formalism allows to recover the wall absorption coefficients, but also to rigorously define the wall diffusion coefficient, heuristically introduced in room acoustics to improve prediction, but difficult to measure due to its vague definition. Applications are varied: recording studios design, acoustics of automotive interiors, multichannel sound reproduction, or even sound propagation in streets.

     Perception and sound quality - psycholinguistic approach to the "meaning" of soundscapes. On demand form the French Ministry of Environment as well as industrial partners within the French program PREDIT, sounscapes have been studied for some years in collaboration with LCPE (Danile Dubois). 5 Ph.D theses have resulted from the project. The approach is based on "ecological validity", that is, preserving original meaning and the subjects' original reactions in a simulation context, and a linguistic analysis of the subjects' utterances, in order to reach their "mental representations" (that is, the organisation of their knowledge). Next step was its application to the articulation between sound signals and their meaning, in order to develop advanced acoustical indices (2 Ph.D.). The last step was to include the experience of local residents in architectural and urban design (coll. Guillaume Faburel, Institut dUrbanisme de Paris) and lead to a book and to a grant from the French Department of Environment. We are presently applying this method to the characterization of the listening experience of music lovers in 3 Parisian concert halls.
