Abstract
In a process and a device for the acoustic testing of a unit under test, the unit under test is subjected to sound excitement and the sound generated in the region of the unit under test is recorded and evaluated. In order to perform a test on such units under test which do not resonate and have no intrinsic sounds, the sound generated in the region of the test is recorded and evaluated while the unit under test is being excited by sound.
