| Abstract |
We propose an auto-fitting system for hearing aids with an interactive evolutionary computation (EC). Conventionally, a doctor or an engineer measures some hearing characteristics of an hearing impair...ed person independently and tunes the parameters of a hearing aid based on them. Therefore, there are many problems in hearing aid fitting. For example, it takes much time, the relation between some hearing characteristics is not clear, parameter setting does not reflect the preference of hearing aid users, the users can not tune by themselves. Our proposed system, in which EC tunes the signal processing parameters to compensate impaired hearing and human evaluate processed sounds, has possibility to resolve these verious problems. We organized a proto-type fitting system which includes a band gain control as a signal processing part and have shown that EC can tunes parameters within practical generations. We are going to apply this system to other popular signal processings of hearing compensation and evaluate themshow more
