Sudden, brief impulse sounds, like many of those shown at 120 dB or greater, are often given in dB (no adjustment). Since the bel is a rather large unit, its use may prove inconven ient. Usually a smaller unit, the Decibel or dB, is used. 10 decibels make one bel. A 10:1 power ratio, 1 bel, is 10 dB; a 100:1 ratio, 2 bels, is 20 dB. Thus the formula becomes Decibels (dB) = 10 log(P 2/P 1) [2] Most of us perceive one sound to be twice as loud as another one when they are about 10 dB apart; for instance, a 60-dB air conditioner will sound twice as loud as a 50-dB refrigerator. Yet that 10-dB difference represents a tenfold increase in intensity.
