I asked an acoustics colleague of mine to check whether the wording of the ANSI definition of sound (picked up on the Internet) was correct as my university library could not source the original publication. I received an illuminating response in turn in which an acoustician pooh-poohed the ANSI definition (the supposed standard acoustic definition).
The original definition is: "(a) Oscillation in pressure, stress, particle displacement, particle velocity etc., propagated in a medium with internal forces (e.g. elastic or viscous) or the superposition of such propagated oscillation" or the "(b) Auditory sensation evoked by the oscillation described in (a)." The definition has the following footnote: "Not all sounds evoke an auditory sensation, e.g., ultrasound or infrasound. Not all auditory sensations are evoked by sound, e.g., tinnitus." American National Standard, Acoustical Terminology. ANSI/ASA S1.1-2013. |
