HOW MUCH DO YOU REALLY KNOW ABOUT SPL LEVELS?
Before you go out and design yourself a 140 dB plus SPL monster,
you might want to consider the following:
Nuclear Explosion 200 dB +
Airplane Engine take off at 100 feet 140 dB
Jack Hammer 130 dB
Normal conversation speech 60 dB
If you have dreams of rocking around your neigh-
borhood, blowing away Mr. Rogers and all your friends
with decibel levels of 160 or higher, you might think twice. In fact, in
many areas if your place of employment is louder than 85 dB, your boss
is obligated to provide you with ear protection. Therefore, should you
choose to expose yourself to SPL greater than 100 dB by cranking up
your system, you should utilize some sort of ear protection.
Now we don’t want to rain on your parade or discourage you from
“letting it loose”, but do be careful with your ears because like your brain
cells, once your hearing is gone, it don’t come back. Of course always
avoid inhaling, especially through your ears. Since many of you get
caught listening to your music, we have equipped your Epicenter InDash
with a warning LED that comes on when it measures sound pressure
levels greater than 120 dB. Above 120 dB you must use hearing protec-
tion to avoid damage!
