Preferred Frequencies and Filter Band Center Frequencies for Acoustical Measurements

This standard defines preferred frequencies and nominal filter band center frequencies to be used for acoustical measurements. Exact filter center frequencies for constant percent bandwidth filter banks are calculated using ordinal integer band numbers. The differences between the preferred frequencies for pure tone measurements and constant percent bandwidth filter center frequencies are described. Controlled free sound field for acoustical measurements in a confined space within the facility.
