Title:
ACOUSTIC CHARACTERISTIC ANALYSIS SYSTEM AND ACOUSTIC CHARACTERISTIC ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2024/084811
Kind Code:
A1
Abstract:
Provided are an acoustic characteristic analysis system and the like which enable a user to experience, in a simulated manner, a sound from a sound source audible in a prescribed acoustic space. The acoustic characteristic analysis system comprises a control unit that outputs, as an audible signal and on the basis of characteristics of an acoustic space (1) which is a real space or a virtual space, a reception sound signal to be received when a user experiences, in a simulated manner, a sound from a prescribed sound source (2) audible in the acoustic space (1). The control unit measures reverberation time on the basis of a prescribed sound collected in the acoustic space (1) by a sound collection device (20), and calculates an average sound absorption rate on the basis of the dimensions of the acoustic space (1) and the reverberation time.
