TECHNICAL CHARACTERISTICS AND PERFORMANCES

(1) Sound power level is a laboratory measurement of the sound power emitted by the product, but it does not correspond to the sound perceived. Used by acoustics specialists, it allows to measure the sound pressure level of the product in its working environment. (2) Acoustic pressure at 1m from HP, 1,5 m height, open field, directivity 2. (3) Models with electric back up. (4) Acoustic pressure at 5m from HP, 1,5 m height, open field, directivity 2.
