- 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/M2 is 60 dB
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 1x10-11W/M2
is that it?
