Answer:
Sound intensity is 630.95 W/m².
Explanation:
It is given that,
The decibel level of the sound, I(dB) = 148
Sound intensity level is given by :
[tex]I(dB)=10log_{10}(\dfrac{I}{I_o})[/tex]
[tex]148 = 10\log_{10}(\dfrac{I}{10^{-12}})[/tex]
[tex]14.8 = log_{10}(\dfrac{I}{10^{-12}})[/tex]
After solving above equation using calculator we get,
[tex]I=630.95\ W/m^2[/tex]
So, the intensity of a sound is 630.95 W/m². Hence, this is the required solution.
