Klaxon Siren Sound Power Tests

On the 1st August 2014 after a month's of planning the first Klaxon siren, a 7.5 kW GP10, was acoustically tested for sound power level for Haztek International with representatives from Chevron present - Dr Kurt Bozenhardt and Mr Alex Stresyuk . This was a team effort from the concrete lab, the metal workshop, and the acousticians. The smaller siren reached levels above 135 dB! Yet it was barely audible outside the anechoic chamber!
