150 spl is a measure of pressure how many lbs per in squared


Recommended Posts

I want to put a glass window in the top of my box and my freind thinks that the wood trim i want to use will not hold, ( be airtite)....

So how many pounds per square inch would it be if i was hypathedically hitting 150 with 2 dc lvl 5 18s on a sound digital 8k

OMG GOOOGLE

1 psi is equal to 170.7dB and atmospheric pressure is around 15 PSI and 1 atm is equal to 194dB( theorictly, if i measure the spl of the atm at 101,3KPa and atm drop to 0 KPa, the meter is suposed to indicate 194dB) Remember that spl is relative number.

110dB = 0,0009PSI = 0,006KPa

120dB = 0,003 PSI = 0,02 KPa

130dB = 0,009 PSI = 0,06 KPa

140dB = 0,003 PSI = 0,2 KPa

150dB = 0,09 PSI = 0,6 KPa

160dB = 0,3 PSI = 2 KPa

170dB = 0,9 PSI = 6 KPa

180dB = 3 PSI = 20 KPa

190dB = 9 PSI = 60 KPa

194dB = 15 PSI = 101 KPa

Higher is'nt possible in normal atm !!

you can cook bacon shirtless if you're not a pussy...lol

not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

if its just regular glass and not plexi it has a chance. i dont think you realize how much force/pressure two lvl5's are going to make inside that box

Not to mention the stressed placed on the screw holes.

You also have to take in account that a material will maintain it's structural integrity only passed 2x the diameter of the whole in it.

So a 15" hole would weaken the material about 30" in diameter around that.

If I remember that formula correctly.

I think he just wanted a viewing hole, not as the baffle. So it would probably be fine.

150 on the dash can translate easily to mid 160s in the enclosure.

I strongly recommend using plexiglass instead just so you can secure the seams stronger.

I drill through the plex to run screws into the wood, and also use a glue/sealer.

The material will hold firm at 1" thick. its the seams you should worry about.
