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. As you try to get back to sleep, your next-door neighbor on the other side of your house also begins to mow the lawn with an identical mower the same distance away. This situation annoys you greatly because the total sound now has twice the loudness it had when only one neighbor was mowing.
The reason why the given situation is impossible.
Each lawn mower produces sound of same amplitude as they are both equidistant.
Write the expression for sound level
 Â
Here,
Using two lawn mowers increase the intensity by a factor of 2.
Substitute,
