1. With singular agreement. The branch of physics concerned with the properties and phenomena of sound, sometimes esp. in relation to hearing or speech.In quot. 1684 perhaps: the branch of science concerned with direct sounds, i.e. those which are not reflected or refracted before reaching the hearer. Cf. catacoustics n. 1, diacoustics n.aeroacoustics, bioacoustics, electroacoustics, speech-acoustics, etc.: see the first element.
