How Does Distance Affect Perceived Loudness and Intensity in Tuning Forks?

[Smartie404]

This is my first post, so I really hope I'm not in the wrong area. I'm doing a lab is class and I'm confused as to what formula I'm supposed to use.

Problem: Use the tuning forks to test the difference between perceived loudness and actual intensity. Use the formula to calculate intensity based on distance and your own ranking scale to give a number for loudness.

Tuning Fork 320 Hz.

Distance(m) .2 .15 .17 .1
Intensity(1-10) 2 1.6 1.4 1

Thanks in advance.

This should be in the homework section.

The formula you are after is the inverse square law.
