Modal Resonances

Sound in enclosed spaces behaves fundamentally differently from sound in a free field. In a free field, sound leaves the source and travels outward unimpeded. It is easy, for example, to determine the sound-pressure level at any distance from the source. In most enclosed spaces, sound from the source is reflected from boundary surfaces such as walls, floor, and ceiling. The resulting sound-pressure level at any point in the enclosure is a combination of the direct sound and the reflected sound. In particular, modal resonances are established; the sound-pressure level will be different at different places in the enclosed ...
