Sound Levels

Fan sound levels, measured in a reverberant chamber in accordance with BS848 Part 2 1985. Published dB(A) figures are free field sound pressure levels at 3m with spherical propogation at a reference level of 2 x 10-5 Pa (20 micro-Pascal). The sound power level spectra figures are dB with reference level of 10-12 Watts (1 pico-watt). To ensure minimum noise levels during speed control, an auto transformer speed control is recommended.
