Title:
How the hearing aid system works and the hearing aid system
Document Type and Number:
Japanese Patent JP6322339
Kind Code:
B2
Abstract:
A hearing aid system and method of operating the hearing aid system, wherein the impedance of a hearing aid receiver is measured, values of two hearing aid receiver parameters are derived based on the measurements, an electro-acoustical model of the receiver is provided using the derived values, the model is used to predict (i) a non-distorted membrane displacement based on the derived values of the parameters measured at a zero bias voltage, and (ii) a distorted membrane displacement based on the derived values of the parameters measured at a non-zero bias voltage, based on the predicted displacements, a compensation gain is determined suitable to compensate non-linear distortion of the hearing aid receiver, and the compensation gain is applied to the processing of a hearing aid input signal.
