Directional microphone arrangement and method for signal processing in a directional microphone arrangement
An arrangement of five figure-of-eight microphones is configured in such a way that receive signals that are at least approximately proportionate to sin( ), cos( ), sin( )*cos( ) or Sin 2 ( ) are generated, i.e., first and second order directional microphones can be created. A method for processing...

( ) are generated, i.e., first and second order directional microphones can be created. A method for processing signals is also configured in such a way that suitable receive signals are selected and various trigonometric functions that are dependent on the orientation of the main lobe are generated and combined with the receive signals in such a way as to produce controllable directional microphone arrangements with first and/or second order characteristics. |
