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 .
ANC wind noise mode optimization combines the acoustic performance of the headset and ANC configuration，the algorithm adjusts ANC controller parameters based on wind noise detection results, optimizing ANC performance in feed-forward paths for wind-noise and noise environments.Adaptation for occasional wind noise interference and strong noise environmental , balancing the wind noise interference and ANC performance, and realizing smooth transition of the system state.
The environment adaptive ANC algorithm analyzes the real-time distribution of environmental noise and speech activity, combined with preset different ANC modes, automatically switches between ANC modes to achieve a balance between noise cancellation depth and comfort, and solves the tedious operation of switching between different ANC modes.
