Question

You are standing in the middle of a large room listening to a cacaphony of sounds. Rank the intensity of the sounds from each source (1=loudest, 2= next loudest, ...) Consider all objects to be right next to you. If two values are within 0.1 dB from each other, consider them to be the same.
1 2 3 4 5  Two buzzers each producing a sound with intensity level of 50 dB.
1 2 3 4 5  An object emitting a sound with an intensity level of 60 dB.
1 2 3 4 5  An object emitting a sound with an intensity of 1.0×10-9 W/m2.
1 2 3 4 5  An object emitting a sound with an intensity level of 10dB.
1 2 3 4 5  100 buzzers each producing a sound with intensity level of 30 dB.

Explanation / Answer

1)x = 10^(5.0) * 2
x = 10^(5.0 + log(2))
x = 10^(5.30)

2)x = 10^6

3)x = 10^3

4)x = 10^1

5)x = 10^(3.0) * 100
x = 10^(5.0)
