Abstract
Oral-binaural room impulse responses (OBRIRs) are the transfer functions from mouth to ears measured in a room. Modulated by many factors, OBRIRs contain information for the study of stage acoustics from the performer’s perspective and can be used for the auralization. Measuring OBRIRs on human is, however, a cumbersome and time-consuming process. In the current study, some issues of the OBRIR measurement on human were addressed in a series of measurement. With in-ear and mouth microphones, volunteers sang scales, and a simple post-processing scheme was used to refine the transfer functions. The results suggest that OBRIRs may be measured consistently by using the proposed protocol, where only 4~8 diatonic scales need to be sung depending on the target signal-to-noise ratio.
