T12 - Large Room Acoustics: Basics and New Developments
Diemer de Vries - Amsterdam, The Netherlands
In the sound recording and reproduction chain, the audio engineer has to deal with the acoustics of the environment—usually an enclosed space, a “room”—he or she is working in. The physical properties of the acoustics of a room can be studied by advanced measurements or simulations, but what counts at the end is the perceptual quality of the acoustics. The challenge of the modern room acoustics researcher is to find an unambiguous relation between physics and perception. In the tutorial—which is focused on large rooms—it will be discussed how, long ago, only “reverberation time” was considered as the important parameter. Later, and until now, parameters were derived from impulse responses. Recent developments show that also these responses may have had their longest time as the scientific foundation of room acoustics.
