Title:
ACOUSTIC APPARATUS AND TRANSFER FUNCTION DETERMINATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/087572
Kind Code:
A1
Abstract:
An acoustic apparatus (100, 200). The acoustic apparatus (100, 200) comprises a sound production unit (110, 210), a first detector (120, 220), a processor (130), and a fixing structure (180). The sound production unit (100, 200) is used for generating a first sound signal according to a noise reduction control signal. The first detector (120, 220) is used for acquiring a first residual signal. The first residual signal comprises a residual noise signal, which is formed by superimposing environmental noise with the first sound signal at the first detector (120, 220). The processor (130) is used for estimating a second residual signal at a target spatial position (A) according to the first sound signal and the first residual signal, and updating the noise reduction control signal according to the second residual signal; and the fixing structure (180) is used for fixing the acoustic apparatus (100, 200) at a position in the vicinity of an ear (230) of a user without blocking an ear canal of the user, and the target spatial position (A) is closer to the ear canal of the user than the first detector (120, 220).
