Patent ID: 6865275

Claim:
A method for establishing a desired transfer characteristic which converts an acoustical input signal impinging on a microphone arrangement into an electric output signal as a function of the angle at which said acoustical input signals impinge on said microphone arrangement, said method comprising the steps of: providing at said microphone arrangement a first microphone sub-arrangement and a second microphone sub-arrangement, each microphone sub-arrangement having a transfer characteristic which converts said acoustical input signal impinging on said microphone sub-arrangements into an electric output signal of the respective sub-arrangement, said transfer characteristics of said first microphone sub-arrangements being different from said transfer characteristic of said second microphone sub-arrangement with respect to said acoustical input signal; forming a ratio of said output signals of said first and second microphone sub-arrangements, thereby generating a ratio result; forming a saturated product with said ratio result as one factor, thereby clipping said product at a predetermined or predeterminable value and generating a saturated product result; and generating said electric output signal as a function of said saturated product result.
