| acoustics | <physics> The science of sounds, teaching their nature, phenomena, and laws. "Acoustics, then, or the science of sound, is a very considerable branch of physics." (Sir J. Herschel) The science is, by some writers, divided, into diacoustics, which explains the properties of sounds coming directly from the ear; and catacoustica, which treats of reflected sounds or echoes. Origin: Names of sciences in -ics, as, acoustics, mathematics, etc, are usually treated as singular. See -ics. Source: Websters Dictionary (01 Mar 1998) |
