Scope

This standard covers letter symbols¹ for physical quantities² used in the science and technology of acoustics; it also covers abbreviations for a number of acoustical levels and related measures that are in common use.

The science and technology of acoustics include sound, ultrasound, and infra-sound in all media: gases, especially air; liquids, especially water; and solids are examples of media with which acoustics is concerned. There are many specialties in acoustics, a few of which are speech, hearing, music, noise control, vibration, shock, and sonar.

The symbols given in this standard are intended for all applications, including use in text and equations; in graphs and diagrams; and on panels, labels, and nameplates.

"General principles of letter symbol standardization" common to SCC14 standards are given before the more specialized "principles applicable to letter symbols and abbreviations for quantities used in acoustics." These are followed by the "introduction to the tables" and a "bibliography."
