Answer:
L = 65 dB
Explanation:
As we know that the intensity of the sound is given as
[tex]I = 3.2 \times 10^{-6}[/tex]
now the loudness is given as
[tex]L = 10 Log \frac{I}{I_0}[/tex]
now we have
[tex]I_0 = 10^{-12} watt/m^2[/tex]
now we will have
[tex]L = 10 Log\frac{3.2 \times 10^{-6}}{10^{-12}}[/tex]
now we will have
[tex]L = 65 dB[/tex]
