Recommendation on preferred frequencies for acoustical measurements
出版:British Standards Institution

专家解读视频
For certain acoustical measurements a constant frequency increment is a suitable spacing. More commonly, however, a constant percentage increment is adopted and the test frequencies then form a geometric series. The standard deals with the geometric series and is not intended to apply where a constant frequency increment or other particular spacing would be more suitable. It does not deal with frequencies for music.
