Noise Measurement Octave Bands at Donald Bernice blog

Noise Measurement Octave Bands. Octave bands are identified by their centre frequency. Octave band meters for octave band analysis and the selection of hearing ppe & noise control; Room acoustics and acoustic properties. A sound level meter fitted with octave band filters has the ability to split the audible spectrum into smaller bands, identifying the frequency content of the noise. Decibel a, b and c calculations. The band width increases as the centre frequency increases. The nc rating can be determined by. The criteria curves defines the limits of the octave band spectra that must not be exceeded to meet the occupants acceptance in the actual spaces. An instrument with 1:3 octave band filters, such as the optimus cr:171b, would typically provide 33 bands from 12.5hz to 20khz although some additional bands such as 6.3hz, 8hz and 10hz. For workplace noise we need octave band analysis.
