Patent ID: 7212643

Claim:
A hearing device with a behind-the-ear microphone arrangement not to be placed in the ear canal of an individual's ear, said microphone arrangement having at least one microphone with an output further comprising an electrical/mechanical output converter, characterized by a further microphone, a beam former unit having at least two inputs and an output, one input being operationally connected to the output of said at least one microphone, the second input being operationally connected to the output of said further microphone, the output of said beam former unit being operationally connected to an input of said output converter, said beam former unit together with said at least one and said further microphones having a transfer characteristic of acoustical signals impinging on said at least one and said further microphones to an electric signal at said output of said beam former unit, the amplification thereof being dependent on direction with which said acoustical signals impinge on said microphones and on frequency of said acoustical signals, said direction being 0° in a direction that the individual is facing and 90° substantially in a direction from the individual's ear canal outward from said ear, said transfer characteristic having the following features: a substantially constant amplification independent of said direction of impinging at said frequency of 1 kHz, for said direction being 45°, a larger amplification than for said direction being 135° at said frequency of 5 kHz.
