TECHNICAL DATA
|
|
|
The noise reduction coefficient is established by The American Standards Testing Committed The N.R.C. is a standard method used to determine the absorption characteristics of a given material. The noise reduction coefficient (N.R.C.) is an average of the sound absorption coefficients for the following frequencies:
250-500-1000-2000-4000 HZ.
