Test bench and method for measuring the acoustic insulation characteristic of a test object

摘要

The stand has a transmitting chamber (1) with a sound transmitter array that includes four sound transmitters. The transmitters are arranged in a plane parallel to a dividing wall (3). A controlling unit is allocated to the transmitters via which the transmitters are controllable such that either a diffuse sound field or an essentially unidimensional sound field is optionally created and directed towards a test aperture. An independent claim is also included for a method for measuring the sound insulation and insertion loss of a test object.
