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.
