Respuesta :

about 9.5 watts i think

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]
