Abstract
A hearing aid has a built in or internal test tone generator for providing test tones and noise for diagnostic tests to a user through the receiver of the hearing aid. Alternatively an external test tone generator may be coupled to the hearing aid and selectively coupled to the receiver of the hearing aid for the diagnostic tests. A memory internal to the hearing aid may store real world sounds for diagnostic tests to simulate actual usage of the hearing aid.
