- Homework Statement
- Intensity of sound in a room is 1x10^-6 W/M^2. Object is rated at 25dB. What is the intensity of sound after passing through the object assuming the sound does not go around the object.

- Relevant Equations
- i=10lg(i/i0)dB

1x10^-6 W/M

The sound goes through both mediums --> 25dB *2 = 50dB lost

Therefore the dound after object is 60dB-50dB = 10dB and converting to intensity it is 1x10

is that it?

^{2}is 60 dBThe sound goes through both mediums --> 25dB *2 = 50dB lost

Therefore the dound after object is 60dB-50dB = 10dB and converting to intensity it is 1x10

^{-11}W/M^{2}is that it?
