Homework Statement
Atmospheric pressure is 101 kPa. Compute the acoustic pressure that corresponds to the threshold of pain for the ear. What percentage of atmospheric pressure is this?
Homework Equations
L=20log(P/Po)
Po is a constant = 2x 10-5
threshold of pain for the ear=130db
The Attempt at a Solution
I'm getting 63 Pa (or 0.06%) for the acoustic pressure but it doesn't correspond to the answer which is one of the following.
2%
200%
0.2%
Thanks!
