1.1 This classification provides a single figure rating that can be used for comparing building systems and subsystems for speech privacy purposes. The rating is designed to correlate with transmitted speech intelligence between office spaces.
1.2 Excluded from the scope of this classification are applications involving female speakers or children, languages other than English, and sound spectra other than speech. Thus excluded, for example, would be comparisons of building systems or subsystems for their effectiveness in reducing transmitted noise from machinery, industrial processes, bowling alleys, music rooms, places of entertainment, and the like.
Note 1--Recently published work by Pearsons, et al, may eventually permit the restriction on female speakers to be relaxed.
