Acoustics – Preferred frequencies

This International Standard specifies preferred frequencies for acoustical measurements. The preferred frequencies are based on the RlO series of preferred numbers in ISO 3 and the reference frequency of 1 000 Hz.
For most acoustical measurements and presentations of data, a frequency spacing based on a constant percentage increment is generally preferred and the test frequencies then form a geometric series. For certain acoustical measurements, a constant frequency increment is a suitable spacing.
The International Standard deals with the geometric series and is not intended to apply to cases where a constant frequency increment, or other particular spacing, would be more suitable, or where there may be good reasons for the adoption or retention of other frequencies.
This International Standard does not deal with:
- frequencies for music;
- all audiometric frequencies;
- series other than RlO from ISO 3.
