A method of operating a hearing aid system () based on processing two groups of interleaved frequency bands such that one of the two groups of frequency bands is attenuated with respect to the other and such that it alternates with time whether one or the other of the two groups are attenuated and a hearing aid system () for carrying out the method.

Hearing aid system and a method of operating a hearing aid system

A method () of fitting a hearing aid system comprising identification of an auditory neurodegeneration of a person based on the ability of the person to perceive small differences in intensity level, a computerized device () and a non-transitory computer-readable medium storing instructions thereon, which when executed by a computer perform said method.

Method of fitting a hearing aid system, a hearing aid fitting system and a computerized device

A method of processing a signal in a hearing aid () comprises splitting an input signal into a multitude N of hearing aid frequency bands, receiving an input signal from an acoustical-electrical transducer, splitting the input signal into a multitude N of hearing aid frequency bands using a first filterbank, estimating speech, noise and hearing loss levels in said frequency bands, using an auditory model of the cochlea for a hearing impaired person to provide excitation values for speech and noise in said frequency bands, using said excitation values to calculated a speech intelligibility measure and optimizing said speech intelligibility measure by iteratively varying the applied gain in the hearing aid frequency bands. The invention also provides a hearing aid ().

Method of operating a hearing aid and a hearing aid

In a method of fitting a hearing aid system, a hearing aid user's hearing loss is classified and the hearing aid fitting is adapted in response to this classification. The hearing loss classification is, in one example, classified by determining an audiogram for the user, testing the user's hearing function under conditions that, for a user with that audiogram, would result in a predicted intelligibility, and comparing the measured intelligibility to the predicted intelligibility. Also disclosed is a hearing aid fitting system () adapted to carry out the method.
