Document Type and Number:
WIPO Patent Application WO/2023/065368
Kind Code:
A1
Abstract:
The present application relates to a signal processing method and apparatus, and a storage medium and a vehicle. The method comprises: receiving, at a noise source, a first audio signal that is collected by one or more first sensors; receiving, at a human ear, a second audio signal that is collected by one or more second sensors, wherein the first audio signal and the second audio signal are used for determining parameters for processing the first audio signal according to a first processing mode; and sending a third audio signal, which is determined after the first audio signal is processed according to the first processing mode, wherein the third audio signal is used for instructing a speaker to emit a sound wave, and the sound wave is used for canceling noise at the human ear. Therefore, the capability of real-time adjustment of parameters during noise reduction can be realized, such that rapid noise reduction can be achieved; moreover, the amount of noise reduction is large, and a noise reduction effect is better.
