Abstract:
1. An environment adaptive type hearing aid for generating an output sound from an ambient sound, comprising: an input section that inputs the ambient sound; a predicted environment referring section including a predicted ambient environment table storing a predicted ambient environment candidate corresponding to an ambient environment other than the ambient sound set in advance for the hearing aid; an environment estimating section that estimates an ambient environment candidate of the hearing aid on the basis of the ambient sound input by the input section and estimates an estimated ambient environment on the basis of the ambient environment candidate and the predicted ambient environment candidate; a hearing ability compensation system determining section that determines a compensation system for the hearing aid on the basis of the estimated ambient environment estimated by the environment estimating section; a hearing ability compensating section that processes the ambient sound input by the input section on the basis of the compensation system determined by the hearing ability compensating system determining section; and an output section that outputs the ambient sound processed by the hearing ability compensating section as the output sound.
