The Noise Limiting System combines the benefits of Gain Dependent Expansion and Adaptive Noise Reduction to combat both low- and high-level noise sources.

Gain Dependent Expansion addresses low-level noise, such as circuit noise or ambient noise. The amount of attenuation applied to low-level noise varies based on each patient’s gain setting at each frequency, with lower-gain settings receiving more expansion and higher-gain settings receiving less expansion. Adaptive Noise Reduction attacks both low- and high-level steady-state noise sources. As the input level of the noise increases, the attenuation of the noise becomes more aggressive.
