A high directivity boundary microphone () is disclosed, build up of a normal unidirectional microphone element () with cardioid-directivity behavior. The microphone element () is placed on a holder plate (), with a membrane () of the microphone element () facing a plane () where a holder (), comprising the holder plate () and a holder feet (), is placed upon. The holder () ensures that the microphone element () is aligned at an angle () of preferably 35° respective to the plane (). In this position, the microphone element () can detect direct sound () in a defined speech area (A,B) as well as delayed sound () that is reflected at the plane () beneath the microphone element (). Outside the defined speech area (A,B) the sensitivity is strongly reduced.
