Homework Help: Sound Wave Intensity/Sound Level

  1. Dec 10, 2006 #1
    The intensity of sound wave A is 100 times that of sound wave B. Relative to wave B the sound level of wave A is:
    a. -2 dB
    b. +2 dB
    c. +10 dB
    d. +20 dB
    e. +100 db

    Using 10logbase10(I/Io) - 10log(100/1) - Would the answer be 20 dB?

    As long as you are calculating the relative intensities, yes. You are correct.
