Textbook Problem

Why is the following situation impossible? It is early on a Saturday morning, and much to your displeasure your next-door neighbor starts mowing his lawn.

Write the expression for sound level

  β10log(II0)

Here, β is the sound level, I is the intensity of the sound wave, I0 is the reference intensity.

Using two lawn mowers increase the intensity by a factor of 2.

Substitute, 2I0 for I in the above equation to find β
