theoretically.. is this possible?

[mikescanlon 10+ year member]

okay.. so i read on the internet that the max SPL is based on the atmospheric pressure, and a few other things..

so theoretically if i change the atmospheric pressure in my vehicle.. would it change my SPL rating? does sound travel..
responses from smart people that know only please : )

i'm going to look into this more... i dont think i'd actually waste my money sealing off my vehicle like that to be able to change the pressure inside, but i like looking into possibilities.

edit: by MAX SPL i mean the 200+ db that was hit at the apolo launch pad.. was that due to the changed pressure of the whole thing going off there? or what?

what kind of SPL does an atomic bomb hit?.. a nuke in space would hit higher spl? enough to destroy more stuff? maybe i'm in the wrong forum for this : )

Colder air is denser. Running your AC can change the pressure, but it would be impossible to change it to the point where you are wanting to go. If I remember correctly the atomic bomb was mesured at 190db. Even 180db would be enough to tear your car apart.

It's possible to do in excess of 220db under water //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

A good example of this is to take a 2"x4"x20', put your ear to one end, and have someone else softly tap the other side. The density of the lumber lets sound waves travel from one end to the other so easy, that you lose almost no SPL from the tap, even after 20 feet.

All that aside, it could be good for a solid quarter/half dB. Assuming you can get a very high amount of pressure into the vehicle. Nothing big enough to make it worth the effort, mind you. =)

lol. i was soooooooooo about to say that

good replys.

so pretty much if you fill your car with water, you'll hit some good db's!

i wasn't asking soo much for vehicles, just for the sake of science and knowledge.

thanks guys : )

hey thats our idea! lol...filling a car up with water....thats my friends idea, haha. i dont think he got past the how to not get a sub/amp/everything dry in a car filled with water though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
