World Record 180.5 dB From a Single Subwoofer

On August 31st the bar was set just a bit higher in dB Drag competition. Alan Dante set the new record at 180.5dB with a single subwoofer. Let me say that again... WITH A SINGLE SUBWOOFER.



Alan Dante's concrete filled Volvo is louder than dynamite, jet engines, gunfire, NASA rockets and pretty much any sound you can imagine for that matter aside from nuclear bombs and natural disasters.



The 180.5 score was done with a Digital Designs 9918Z 18" subwoofer receiving 26,000 watts of power from four Stetsom 7KD amplifiers. Fifteen Powermaster 16 volt batteries were used as well. Rumor has it that the setup is good for at least another decibel, so expect to possibly see an even higher number in the near future.

I highly doubt that 180db can be reached. I would like to see the microphone that is used to measure it and what referance is used to measure the microphone. From my understanding a sound wave that measures in that power range would incinerate anything with in 1000 ft. There is also a problem of compresion distortion that air produces which is accounted for when people like NASA look into ingniting the solid booster engines.

I worked at Magna (the auto parts manufacture) in thier R&D labs testing out a new way of blasting holes in bumpers. We used about 15 MVA shot for abut 15 ms into a coil which will blast a hole in a 1/8" channel with extremely clean edges. We were looking at a way around using high powered lasers (very $$$$). We were only producting about 160dbs of noise - which would shatter glass at 50 meters. Nobody was allowed in the test chamber. So at a 180dbs I'm not so sure I can believe that. Unless it was 'A' weighted measurement
