Answer:
The intensity level of the sound wave due to the ambulance is 153.5 dB.
Explanation:
The intensity level of the sound wave due to the ambulance can be calculated using the following equation:
[tex] \beta = 10log(\frac{I}{I_{0}}) [/tex]
Where:
I: is the intensity of the sound wave from a siren = 111.2 W/m²
I₀: is the reference intensity = 1.0x10⁻¹² W/m²
[tex]\beta = 10log(\frac{111.2 W/m^{2}}{1.0 \cdot 10^{-12} W/m^{2}}) = 140.5 dB[/tex]
Now, since the second sound wave from a nearby ambulance has an intensity level 13 dB we have:
[tex] I_{a} = 13 dB + 140.5 dB = 153.5 dB [/tex]
Therefore, the intensity level of the sound wave due to the ambulance is 153.5 dB.
I hope it helps you!
