1.1 This classification covers methods of calculating single-number acoustical ratings for laboratory and field measurements of sound attenuation obtained in one-third octave bands. 1.2 The name given to the single-number rating is assigned by the test method that invokes this classification. 1.3 Test methods that invoke this classification include: 1.3.1 Test Method E90 The single-number rating is called sound transmission class (STC). 1.3.2 Test Method E336; Single-number ratings are field sound transmission class (FSTC), noise isolation class (NIC), and normalized noise isolation class (NNIC). 1.3.3 Test Method E596; the single-number rating is called noise isolation class (NIC). 1.3.4 Test Method E1414; The single-number rating is called ceiling attenuation class (CAC). 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

This standard is referenced in the 2012 International Green Construction Code™.
