Organization: ASTM International
Publication Date: 1 September 2010
Status: inactive
Page Count: 4
ICS Code (Acoustics in building. Sound insulation): 91.120.20
significance And Use:

These single-number ratings correlate in a general way with subjective impressions of sound transmission for speech, radio, television, and similar sources of noise in offices and buildings. This... View More

scope:

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.
