Abstract
A hearing aid can be tuned while worn by a user according to a heuristic method, including select an adjustable parameter and an stimulus having audio energy characteristics related to the adjustable parameter. The stimulus is played via a calibrated audio output device and amplified by the hearing aid. After selecting a user perception query associated with the adjustable parameter, feedback is obtained from the user indicating that the stimulus was not perceived neutrally. A perceptual adjustment curve and a threshold curve are determined according to the user feedback, and an estimated perception curve that estimates the user's perception of the stimulus is determined. When at least a portion of the estimated perception curve exceeds a threshold curve, the hearing aid is programmed according to at least one adjustment value determined according to the user feedback value.
