Abstract (en)
The invention relates to a hearing aid system comprising a body worn part comprising a multitude of microphones, each converting an acoustical signal to an electrical input signal, the microphones being arranged in the system to be able to pick up an acoustical signal from several different directions around a wearer of the body-worn part of the system, when worn in an operational position. The invention further relates to a method and use. The object of the present invention is to provide a hearing aid system enabling backwards directed directionality. The problem is solved in that the system further comprises a. One or more processing units, which deduct a backward, or omni-directional and a front oriented signal from the electrical input signals from the microphones; b. A weighting unit, which sets the front and the backward signal in relation and determine the importance of one signal over the other; c. A transition unit, which switches or gradually changes between front- or omni- or backward orientation of the signal perception. An advantage of the invention is that the hearing aid system is suitable for use in a situation where a source of sound intended for being specifically heard is located to the rear of a wearer of the hearing aid system. The invention may e.g. be of importance in a hearing aid for use in situations where the wearer of the hearing aid faces away from an acoustic source intended for being received by the wearer.
