Impulse Noise Reduction

Role
Reduces amplification for sudden, brief noises.

End user benefit
Improves listening comfort and sound quality for impulse sounds like clanking silverware or jangling keys.

Impulse noise reduction works in parallel

With impulse noise reduction

Impulse noise reduction works in parallel with the Warp compression system to ensure that transient sounds are not over amplified. Soft transient speech sounds are preserved. In this example, the sound of plates being stacked was recorded through a ReSound LiNX Quattro hearing aid with (right panel) and without (left panel) impulse noise reduction active.

The boxes show how peaks where overshoot occurs are reduced with impulse noise reduction.
