Abstract

The invention relates to an apparatus for picking up sound waves with a separating body and at least two microphones arranged on the separating body. A pick-up which is particularly true to nature is achieved in such a way that the separating body consists of a reverberant material and is provided with a substantially wedge-shaped arrangement, with two separating surfaces which are inclined towards one another at an acute angle, and that the microphones are arranged at a low distance from the separating surfaces.
