Abstract
A real-time convolution system has been developed to quickly manipulate the auditory experiences of human subjects. The system is used to study perceptions of self-generated speech and music, and responses of talkers and musicians to varying acoustical conditions. It allows talkers in an anechoic environment to experience simulated room responses excited by their own voices. While their direct sound travels directly to their ears, they hear convolved room responses via specialized headphones spaced away from their heads. This presentation discusses the system’s development, as well as its objective and subjective validations. Several existing rooms were modeled using EASE. Oral-binaural room impulse responses (OBRIRs) from these models were generated and implemented with the convolution system. Binaural recordings and measurements from the rooms were also made using a G.R.A.S. KEMAR mannequin. Objective comparisons of the OBRIRs from the measurements and simulations were explored in the investigation. Subjective evaluations of auralizations made from the OBRIR measurements and simulations, and binaural recordings, followed from A/B listening and speaking tests. In the latter, participants spoke in the various simulated acoustical environments and compared and rated the effects of each experience.
