ASTM E413 - 16 - Classification for Rating Sound Insulation

ASTM E413 - 16

Classification for Rating Sound Insulation

Status : Current   Published : April 2016



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 E90The single-number rating is called sound transmission class (STC).

1.3.2  Test Method E336Single number ratings are noise isolation class (NIC), normalized noise isolation class (NNIC), apparent sound transmission class (ASTC), and field sound transmission class (FSTC).

1.3.3  Test Method E596The single-number rating is called noise isolation class (NIC).

1.3.4  Test Method E1414The 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.
