Hello.
The further away from the speakers you are t<span>he less intense the sound will be.
</span>
<span> If sound intensity varies inversely with the square of the distance, you can represent this as: </span>
<span>I = 1/d^2 </span>
<span>If you double the distance: </span>
<span>I = 1/(2d)^2 </span>
<span>I = 1/4d^2 </span>
<span>I = 1/4d^2 </span>
<span>so by doubling the distance, you have 1/4th the intensity.

Have a nice day
