Problem 18E

indicated otherwise, assume the speed of sound in air to be v = 344 m/s. You live on a busy street, but as a music lover, you want to reduce the traffic noise. (a) If you install special sound-reflecting windows that reduce the sound intensity level (in dB) by 30 dB, by what fraction have you lowered the sound intensity (in W/m2)? (b) If, instead, you reduce the intensity by half, what change (in dB) do you make in the sound intensity level?

Step-by-Step Solution:

SOLUTION TO 18E Step 1 Intensity(dB)= (a) Intensity reduced by 30dB I-30= 2 I’=(0.001)I w/m
