Abstract

PURPOSE: To obtain a natural reverberation feel even in listening environment of, for example, a narrow listening space and high sound absorptivity by measuring the impulse response characteristics of the listening space and adding the reflection sounds calculated in accordance with the measured value to a source signal.
CONSTITUTION: The response in a vehicle room 5 by the impulse signal is collected by a microphone 6 installed in prescribed position, such as a driver's seat and is transmitted to an impulse response measuring instrument 7. The impulse signal which is the output of an impulse generator 1 is also impressed as a trigger signal thereto. The impulse response signal measured by the impulse response measuring instrument 7 is sent to a autocorrelation function calculator 8 where an autocorrelation function (ACF) is calculated from the impulse response characteristics and is outputted to an optimum reflection sound calculator 9. Since the optimum reflection sound is calculated from the impulse response characteristics of the listening time in such a manner, the optimum reflection sound is calculated from the impulse response characteristics of the listening time in such a manner, the optimum reflection sound corresponding to the reverberation characteristics of the listening space is added to the source signal. The natural reverberation feel is obtd. even in the listening space of the narrow space and high sound absorptivity, such as, for example, automobile room.
