Sound 1 has an intensity of 45.0 w/m2. sound 2 has an intensity level that is 3.2 db greater than the intensity level of sound 1. what is the intensity level of sound 2?

The intensity level of sound 2 is 93.3\ W/m².

Explanation:

Given that,

Intensity of sound 1 = 45.0 W/m²

Intensity level of sound 2 = 3.2 dB

We need to calculate the intensity

Using equation of the sound level intensity

The intensity of sound 2 is greater than 3.2 dB.

Therefore,

Calculate the intensity of sound 2

Hence, The intensity level of sound 2 is 93.3\ W/m².
