The wind noise detection technology of Sound+ Technology utilizes multiple microphone combinations to analyze the environmental wind noise in real time.The wind creates random and irregular turbulence on the surface of the microphone diaphragm, resulting in disorganized high level noise.The wind noise detection module supports using different microphone combinations to detect environmental wind noise and return the current wind noise level. Accurately determining the wind noise level helps to carefully control the behavior of ANC filters, balancing ANC performance with wind noise interference in strong background noise .
