A window whose area is `2m^2` opens on street where the street noise result in an intensity level at the window of 60 dB. How much acoustic power enters the window via sound waves. Now if an acoustic absorber is fitted at the window, how much energy from street will it collect in 5 h?

Explanation

To solve the problem step by step, we will follow these steps:

### Step 1: Understand the relationship between intensity level and intensity
The intensity level \( L \) in decibels (dB) is given by the formula:
\[ L = 10 \log \left( \frac{I}{I_0} \right) \]
where \( I_0 = 10^{-12} \, \text{W/m}^2 \) is the reference intensity.
