HOW LOUD IS 130DB?

  

The decibel (abbreviated dB) is the unit used to measure how loud a sound is. The decibel scale is a little odd because the human ear is incredibly sensitive. Your ears can hear everything from your fingertip brushing lightly over your skin to a loud jet engine. In terms of power, the sound of the jet engine is about 1,000,000,000,000 times more powerful than the smallest sound that your ears can just barely hear. That's a big difference!

On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. Below is a list of common sounds and their decibel levels, as well as some of our alarms for comparison.

Here's a great link to a study done by Purdue University's Chemistry Department that charts sounds and their relative decibel measurements.
