Abstract
Real ear measurements for a digital hearing aid (DHA) fitting are effected using a probe microphone which senses sound from within the patient's ear. The sound, which is conveyed to the probe microphone using a probe tube, is converted to electrical signals which are input to a direct audio input of the DHA. The electrical signals are digitized by the DHA and relayed to a processing unit which effects the real ear measurements. Alternatively, the DHA itself performs all real ear measurements with only a wired, wireless or no external connection to a command unit.
