Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce a feeling of inarticulation of sound that an ear hole type hearing aid user has by making a vent hole much larger than heretofore. SOLUTION: The hearing aid includes a shell (10) forming the external shape of the hearing aid, a vent hole (20) linking an outer side and a front inner side of the shell (10) to each other, a microphone (13) disposed on the outer side of the shell (10), and a receiver (14) disposed on the front inner side of the shell (10). The vent hole is made as large as possible as long as an audio processing unit can suppress howling. Thus, the large vent hole is formed, so a feeling of inarticulation of a sound that the user has is greatly reduced. COPYRIGHT: (C)2008,JPO&INPIT
