THE vast majority of noise specifications, rating indices, requlations and working procedures are based around overall levels and/or octave or fractional octave frequency analysis. Traditionally, analyses of this type are carried out by passing noise signals through analogue filter sets, using the ‘energy’ (pressure-squared) outputs that result to drive analogue or digital indicators.
