Is there a difference between volume and decibel level?

"Is there a difference between volume and decibel level?"

Volume is not a well-defined measure of sound.  Decibel is defined...as a ratio.

If you have two audio signals, and one is a ten times stronger than the other, you can say it is 10dB stronger. If it is 100x stronger it is 20dB, if it is 100x weaker, it is -20dB. It's a logarithmic formula.

Sound pressure levels (SPL) given in dB refer to 20microPascal at 0dB, which is actually around the threshold level of hearing anything at all. more »
