Linear/Non-Linear

A linear hearing aid is one that adds the same amount of gain to the incoming signal, regardless of how soft or loud the incoming signal is, up to a cutoff point or saturation. A non-linear hearing aid is one that varies the amount of gain added to an incoming sound based upon the intensity of the incoming sound. Usually, in non-linear hearing aids, soft-incoming sounds have more gain added to them than loud incoming sounds.
