Tuning Forks and Sound

  1. Mar 18, 2007 #1
    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.
