Abstract
A hearing aid comprises a noise suppressor that calculates noise suppression gain, an adjustment amount calculator that calculates an adjustment amount on the basis of a signal strength and a noise component strength, and a nonlinear compressor that calculates a reference gain on the basis of a signal strength and specific reference gain information and adjusts the reference gain on the basis of an adjustment amount, thereby calculating a nonlinear compression gain.
