Explanation / Answer

You are standing in the middle of a large room listening to a cacaphony of sounds.
Rank the intensity level of the sounds from each source (1=loudest, 2=next loudest).
Consider all objects to be right next to you.
Ten buzzers each producing a sound with intensity level of 50 dB = 60 dB.
Two buzzers each producing a sound with intensity level of 57 dB = 60 dB.
One hundred buzzers each producing a sound with intensity level of 40 dB = 60 dB.
Four buzzers each producing a sound with intensity level of 54 dB = 60 dB.
An object emitting a sound with an intensity level of 60 dB.
