The score wasnt legal because the mic ripped off the windshield. Then they superglue the mic to the windshield and it still ripped off and did a 184+. My guess is wherever the mic is landing the pressure is obviously greater than in the legal spot.
The best legal score from that car on the ac190 is a 177.6
Which is still damn loud. The South Africans claim to already have 2 cars over 180.
As far as a pressure limit Ive heard air liquifies at 194 db at sea level

err that dosen't make any sense at all.... to liquify a gas you need to cool it.....
compress it
sound PRESSURE

^ compressing a gas gives you more gas in less space..... but its still a gas.....
The exception is if you are below the critical temperature of the gas.... for example nitrogen gas can be compressed into a liquid at 500PSI if the temperature is below -150 degrees Celcius... oxygen is more like -110C. and 700PSI.. of course the colder you are the less pressure you need... (liquid N2 at atmospheric pressure is around -210 degrees!)
But at room temperature its just not possible to make liquid air no matter how much pressure you use....
CO2 on the otherhand will form liquid at room temp around 900PSI...... (thats equivalent to only about 230db
LOL)
