ENVIRONMENT ADAPTIVE TYPE HEARING AID

摘要

There is provided an environment adaptive type hearing aid capable of reducing the erroneous estimation of an ambient environment or the unnecessary changeover of a hearing aid process. The environment adaptive type hearing aid includes an input section (110) that inputs an ambient sound, a scheduled environment referring section (180) having a scheduled environment table (270) to store a scheduled environment candidate corresponding to an ambient environment other than the ambient sound set in advance for the hearing aid, an environment estimating section (200) that estimates an ambient environment candidate of the hearing aid on the basis of the ambient sound and estimates an estimation ambient environment on the basis of the ambient environment candidate and the scheduled ambient environment candidate, a hearing ability compensation system determining section (220) that determines a compensation system for the hearing aid on the basis of the estimation ambient environment, a hearing ability compensating section (130) that processes the ambient sound on the basis of the determined compensation system, and an output section (150) that outputs the processed ambient sound as an output sound.
