Physics

8.7

Explanation:

I_m = Intensity of sound heard by man

I_w = Intensity of sound heard by woman

$\beta$ = Intensity indecibels = 9.4 dB

Intensity of sound is given by

$\beta=10log\frac{I_m}{I_w}\\\Rightarrow \frac{\beta}{10}=log\frac{I_m}{I_w}\\\Rightarrow 10^{\frac{\beta}{10}}=\frac{I_m}{I_w}\\\Rightarrow \frac{I_m}{I_w}=10^{\frac{9.4}{10}}\\\Rightarrow \frac{I_m}{I_w}=8.7$

So, the ratio of sound intensity by the man to the sound intensity just detected by the woman is 8.7
