3148 A Hearing Aid

              A hearing aid is an electroacoustic device which assists hearing of the hearing-impaired.  A hearing aid does not only have the function of increasing volume but also function of clearing to make it easy to hear.  It has various kinds, for example, ITE(In The Ear), BTE(Behind The Ear), BAHA(Bone Anchored Hearing Aids) and so on.  ITE is a type to cover up an external ear, and BTE is a type to hook behind an external ear.  BAHA is a type to implant in the side of head and it transmits sounds using bone conduction.  Recently, while performance increases, it is downsized and placed importance on fashionability.
