Raincheck - Acoustic Data
Plots of Sound Intensity Level
BS EN ISO 140-18:2006 outlines a method of simulating rainfall under laboratory conditions using a water tank with a perforated base, suspended above a test specimen.
Measurements are taken below the specimen within the receiving room to assess the sound intensity level re 10-12 W/m2 (dB). The lower the sound intensity level within the receiver room, the greater the effect of the damping material.
In the acoustic tests below, measurements of sound intensity for each type of rain condition were made directly in accordance with BS EN ISO 15186-1:1997 and BS EN ISO 140-18:2006.
Test subject : (3.7m2) 5no 400 x 2102mm, 0.9mm gauge, 3.5kg/m2, ribbed aluminium standing seam roof with stucco emboss installed at a pitch of 7° below the water tank.
Test Reference: WS219329
