Description

Specifies, for the condition of equal loudness and certain other stated conditions, relationships between sound pressure levels and frequencies of pure continuous tones. These are expressed by means of a bilinear equation for the preferred frequencies in the one-third octave series from 20 to 12500 Hz. A graphical illustration is included.
