Matching the Reverberance of Room Impulse Responses

摘要

This study investigates the subjective reverberance of room impulse responses (RIRs) when directly listened to (rather than convolved with a dry signal such as speech or music). We investigate the effects of gain (or listening level) and background noise level on the reverberance of RIRs measured in concert auditoria. The task of the subjective experiment was to match the reverberance of RIRs to that of a reference RIR by adjusting the exponential decay rate using a slider. Based on objective loudness modeling, gain should have a positive effect on reverberance and background noise have a negative effect. This is confirmed in the results of the experiment.
