Wind noise can significantly degrade the quality of speech during calls. Wind can occur naturally outdoors or from man made sources such as air conditioners and fans. Microphones are very susceptible to wind, and even a light breeze reaching the microphone will cause unwanted low-frequency rumble and distorted voice that make a call unpleasant and hard to understand. SoundClear® WindBlock™ NR uses a highly sensitive and precise two microphone algorithm to quickly detect the presence of unwanted wind noise, and then reliably cleans up the wind noise while enhancing the voice. All you hear is exceptionally clear voice undisturbed by wind.

SoundClear WindBlock reduces wind noise intelligently with its breakthrough proprietary multi mode processing. This technology fully exploits the characteristic differences between wind noise and speech signals and automatically processes the microphone inputs to simultaneously reduce wind noise and enhance speech clarity. The high precision sensor algorithm prevents false wind detection to avoid over processing and preserves spectral details. The result is clear, intelligible speech in a wide range of wind conditions with significant Speech to Wind noise Ratio improvement (SWRI) of up to 25 dB.

The SoundClear WindBlock processing is seamlessly integrated with the renowned SoundClear noise reduction and echo cancellation technologies into one powerful and complete solution. The sophisticated algorithms are tunable to achieve optimal performance for different device designs and microphone configurations, and to meet each end customer’s unique goals. This high performance solution delivers truly outstanding speech quality anywhere without the unwanted interference from acoustic and wind noises.

Acoustic Technologies has always focused on dramatically improving the quality of audio in communications, and removing irritating wind noise is an important part of our mission. SoundClear WindBlock and our expert advice on proper microphone configuration and hardware microphone wind protection will enable your mobile devices to deliver outstanding voice quality that is easy to understand even in windy conditions.
