Ph.D. position in psychoacoustics available in Lyon, France



Cocktail-party in rooms: streaming, binaural hearing and reverberation



Mathieu Lavandier, Département Génie Civil et Bâtiment (team Analyse Physique et Perceptive des Espaces Construits et de leurs Environnements, FRE CNRS 3237)

Nicolas Grimault, Centre de Recherche en Neurosciences de Lyon (team Cognition Auditive et Psychoacoustique, INSERM U1028 – UMR CNRS 5292)


The term cocktail-party is used to describe situations when a listener tries to understand a target speech source when other people around are taking at the same time. When a sound sequence arrives at a listener’s ears, he/she will perceive it as one or more auditory streams, generally corresponding to one or more sound sources. Sounds originating alternately from a target and competing source will need to be separated into two streams for the target to be intelligible. In rooms, reverberation leads to temporal and spectral distortions of speech signals. We want to investigate to which extend these distortions deteriorate the segregation/streaming of competing voices. Listening tests will be designed to evaluate the influence of reverberation on segregation mechanisms based on fundamental frequency differences and differences in source positions.
