Abstract
A hearing aid (1) comprises a housing, two microphones (3, 4), signal processing means provided with user selectable settings, and a receiver. The housing is provided with mechanical sound generating means (5, 11). The sound generating means is capable of providing a specific sound when manipulated by a hearing aid user. The sound generating means is arranged such that the two signals (25), obtained from the specific sound being recorded by the two different microphones (3, 4) will have a negative correlation, making said specific sound identifiable by said signal processing means. The signal processing means are arranged for selecting a specific setting dependent on one or more sounds generated by the sound generating means (5, 11). The invention further provides a method for selecting a setting of a hearing aid.
