Given that i0=10−12 watts/meter2, what is the intensity of a sound for which the decibel level of the sound measures 148? round off your answer to three decimal places.

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 :

After solving above equation using calculator we get,

So, the intensity of a sound is 630.95 W/m². Hence, this is the required solution.
