Answer :
The the loudness that the musical group plays with is expressed as:
D: 98.3
How to find the Value of the Sound Intensity?
The formula to find the loudness of the sound is given by the formula:
L(I) = 10log(I/I₀)
Where I₀ = 10⁻¹²W/m²
We are given that the sound intensity is:
I = 6.7 * 10⁻³ W/m²
Thus:
L(I) = 10 Log ((6.7 * 10⁻³ )/10⁻¹²)
L(I) = 10 Log (6.7 * 10⁹)
L(I) = 10 * 9.83
L(I) = 98.3
