SoundProtect works to clean the signal pathway from these unwanted sounds. Wind noise, which is a phenomenon that often occurs when hearing aids are used outside, is now elegantly reduced by SoundProtect. Sudden sounds, loud and quiet, are also taken care of. The result is a higher quality of signal for the partner AI Noise Reduction (AI-NR) and a cleaner sound for the user.
Two strategies can be employed to counter these noises. Wind noise is managed by careful analysis of the noise level in each microphone. SoundProtect can then select the microphone with the lowest noise level for each band and will adjust this selection over time, ensuring that the cleanest signal is allowed to reach the AI-NR. Transient noises are managed with a fast, effective gain reduction to minimize the impact of the transient noise on the AI-NR.
