    摘要: The method and apparatus according to the invention determines the acoustic spatial characteristics of an enclosure, particularly of a vehicle occupant compartment in a motor vehicle. A piece of equipment emits a useful sound together with a test sound. By analyzing a recorded analysis sound, the test sound is emitted in a psychoacoustic masking range of the useful sound. Advantageously, the covering range of the useful sound is determined in a useful-sound analysis block before the useful sound and the test sound are emitted.
