1. What is the intensity of a sound at the pain level of 120 dB?
2. What is the intensity level of a sound whose intensity is 2.0 x 10^-6 W/m^2?
Use the equation you will find at
as well as your textbook, if you are using one.
0 dB corresponds to 10^-12 W/m^2 of sound intensity. Each 10 dB above that is a factor of 10.
