Relationship Between( Intensity Level and Intensity of Object)

  1. Dec 25, 2011 #1
    A sound is measured to have a decibel level of 30dB.
    If the intensity is decreased by a factor of 2 by how much does the intensity level change?

    β=10 x log(I/Io)
    β=Intensity level
    I=intensity of the object
    Io= Threshold of hearing(human)

    If the I increase so the β increase

    If so the (I/2) so the (β/2) ??

    You can test this by calculating some sample numbers.
