what does spl mean

what does spl stand for

sound pressure level

[51t]

It is measured in decibels (dB). Every 3 dB is a doubling of sound volume. So 6 dB is twice as loud as 3 dB and 9 dB is 4 times as loud as 3 dB.
Also, and I'm not positive about this, but isn't sound inverse squared. Meaning every time you double your distance from the speaker the sound level is divided by 4.

SPL is a scientific term for how loud something is, the higher the #, the louder it is.

wouldn't that mean if you're 2ft away from your sub box and it's hitting 160db, when you're 4 feet away you're only hitting 40db? i know that can't be right

There is no way in hell that can be right.

Your thinking dB is linear but it is logarithmic. If you doubled your distance you should fall off by 6 dB (?).

97 dB is half as loud as 100 dB
103 dB is twice as loud as 100 dB and four times as loud as 97 dB
106 dB is twice as loud as 103 dB and four times as loud as 100 dB and eight times as loud as 97 dB

D***!!! thats confusing if you dont read it carefully!

[violator5spd]

ok ok

you shoulda just said db are doubled in loudness every 3db...

got cha now though

I thought that is what I said

SPL = Super Painful Loudness
"This setup was built specifically for SPL"

SQ = Super *****
"Hey man check out my Alpine SQ setup!"


For those who take offense to this, here's some advice from a great philosopher:

"Don't go gettin all hard on me, Peter. I'm just playin with ya!"
