Wind Guard

Role
To accurately detect wind noise, and adaptively reduce it.

End user benefit
A natural sounding experience, with soft wind awareness in the background and minimal impact on audibility of other sounds in the environment.

Wind Guard

An advanced wind noise suppression system which:

1.

Constantly monitors and stores the gain levels of each of the Warp bands.

2.

Uses dual microphones to recognize the presence of wind; turbulence caused by wind is uniquely identifiable because it is uncorrelated at the two microphones.

3.

Adaptively reduces gain to the same level as before wind was detected.

This sophisticated algorithm varies with the environment and the level of the wind noise, making the reduction personalized to the situation without sacrificing audibility for other sounds.

RESOUND MODEL CHOICE

Note: Wind Guard is only available for hearing instruments with 2 microphones

THE THREE STATES OF WIND GUARD
     
 OFF - no wind noise detected; environmental sound levels monitored OFF - soft wind noise detected; environmental sound levels stored  ON - moderate to loud wind noise detected; gain reduced to stored environmental levels

Moderate   Fc + 3 dB
Strong Fc + 0 dB 
*Fc = Full compensation to the average level of the sound environment (wind noise level)
