    Abstract - (Show below) - (Hide below)

    Sets out special procedures which are necessary for accurate determinations of the sound power when discrete frequencies or narrow bands of noise are radiated by a source. Applies to sources whose spectrum may or may not include broad-band components upon which the prominent discrete frequencies of narrow bands of noise are superposed.

    Scope - (Show below) - (Hide below)

    This standard sets out special procedures that are necessary for accurate determinations of the sound power when discrete frequencies or narrow bands of noise are radiated by a source.
