Solution :

Let, intensity at distance 3 m from the acoustic source is $I_o$ .

We need to find the distance d where the intensity is $\dfrac{I_o}{2}$ .

Now, we know intensity is inversely proportional to square of distance between the source.

$\dfrac{I_o}{\dfrac{I_o}{2}} = \dfrac{d^2}{3^2}\\\\d^2 = 18 \\\\d = 3\sqrt{2}\ m$

Therefore, intensity will be halved at a distance of $3\sqrt{2}\ m$ .
