Title:
MASKING-SOUND CONTROL SYSTEM, SOUND MASKING SYSTEM, MASKING-SOUND CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/238684
Kind Code:
A1
Abstract:
The present invention addresses the problem of alleviating both discomfort given to people by noise and discomfort given to people by masking sound, with improved balance. In a masking-sound control system (1), an optimization processing unit (1d) uses, as a control parameter, at least one of the reproduction sound pressure level (Pa(j)) of masking sound M((j)) emitted from a speaker (2(j)) and speaker position, which is the position of the speaker (2(j)). The optimization processing unit (1d) obtains, as an optimized parameter, a control parameter that minimizes a discomfort level, which is the degree of discomfort given to people by the masking sound (M(j)) and noise (N1) in a target area (Rt). A masking-sound adjustment unit (1e) adjusts the control parameter to the optimized parameter.
