I used a sound sensor in my experiment and hooked it up to the computer and used it to plot a graph of amplitude against time. I then too readings straight off the graph. How would I go by giving a value for the uncertainty in the amplitude?

You're right, I had no idea what I was talking about. Thanks for the info, that really cleared things up. That link wasn't exactly what I was looking for, but I understand it all now. I guess all I needed was some sleep. Thanks a bunch anyways.

Okay, so I have a sound wave (a visual representation). From this I can see the amplitude of the wave, However, I need to know what the sound power or the sound pressure level. Could someone please give me a formula that could help? Thanks
