## Main Question or Discussion Point

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) ??
