Can anyone think of anything major that can be included in the lab that isn't already?

Interference (Sound)
I'm trying to write a lab using the portable speakers in the storage room. Right now I'm including interference due to two sounds of the same frequency in different phases, beating due to two different frequencies, and determining the wavelength by measuring the distance between successive destructions.

Also, does anyone know of a good way to get ringing noises out of your ears? Seriously, I'm suffering from major overexposure and it's annoying.
ReplyDeleteYou might read throught the Properties of Sound lab we have for some ideas. Also, CPO science had a cool lab of finding your hearing range and looking at intereference. I'll try to find a copy of it for you.
ReplyDeleteI'm liking the interference quite a bit. Could tie that in to how speaker placement is important for faking surround sound, or active noise cancellation headphones.
ReplyDeleteYeah, I was planning on making my overview about noise cancellation headphones and even though the math may be too difficult for them to do during the lab, I would have a separate pane that they could play around with: a seen from above picture of a room with speakers so many feet apart at such and such distance from an X long couch; move the stick man slider icon to various positions on the couch and see the amplitude at that point.
