AB  - The interaction between a loudspeaker and the enclosed space, into which it emits sound, is important for the resulting sound quality. The influence of a listening room on the low frequency behavior of a loudspeaker can be characterized by the ratio of the mean-square sound pressure and the sound power emitted. This ratio is referred to in the literature as room gain and investigations of listening rooms have been published. This paper presents an investigation of the concept of room gain as applied to a car cabin. The mean-square sound pressure as well as the sound power emitted by a low frequency loudspeaker was measured in a real car at three positions. Despite the fact that a car cabin is a significantly different enclosed space compared to a listening room, a clear tendency of increasing room gain at lower frequency was found. This tendency was found to be independent of loudspeaker position.
