Chapter , Problem 5.3.47(choose chapter or problem)
In 4347, sound in decibels is measured by comparing the sound intensity, , to a benchmark sound 0 with intensity 1016 wattscm2. Then, Noise level in decibels = 10 log(0). (a) Let 1 and 2 represent the decibel ratings of soundsof intensity 1 and 2, respectively. Using log properties,find a simplified formula for the difference betweenthe two ratings, 2 1, in terms of the twointensities, 1 and 2.(b) If a sounds intensity doubles, how many decibelslouder does the sound become?
