Adaptation of singers to physical and virtual room acoustics

Résumé

As observed with instrumentalist musicians, singers are expected to react to variations of the acoustics of the venues where they perform by adapting their voice production. To which extent do these changes happen and how are they related to specific variations of room acoustic conditions? And does it make a difference whether they are physically present in the room or whether the room is simulated electro-acoustically? These questions were addressed by recording two musical solo pieces sung by four singers in eight physical acoustical environments. In addition to close-microphone recordings, binaural room impulse response datasets were measured at the position of the singer in order to reproduce the acoustical space through dynamic binaural synthesis. Room acoustical simulations were performed corresponding to the physical rooms and measurement configurations. The experiment was then replicated in an anechoic chamber where the singers would hear themselves in the various measured and simulated virtual spaces. The performances were analysed through automatic musical feature extraction and statistically related to the room acoustical parameters of each venue by means of mixed regression models. Results revealed statistically significant, but highly individual adaptation strategies, both in physical and virtual environments.
