Final Paper Topic |
|
|
For the Final Project I am going to do my research on active noise cancelation. The technology is usually use for controlling noise in enclosed spaces such as ducts, vehicle cabins, exhaust pipes, and headphones. Note, however, that most demonstrations have not yet made the transition into successful commercial products.
One
exception, active noise control headphones, has achieved widespread
commercial success. Active headphones use destructive interference to
cancel low-frequency noise while still allowing the wearer to hear mid-
and high-frequency sounds such as conversation and warning sirens. The
system comprises a pair of earmuffs containing speakers and one or more
small circuit boards. Some include a built-in battery pack, and many
allow exterior signal inputs such as music or voice communications.
Used extensively by pilots, active headphones are considered
indispensable in helicopters and noisy propeller-driven aircraft.

I have uploaded my final paper rough draft on noise cancelation. The
paper that I posted does not have any clear set of structure as of yet.
I am trying to find more resources about noise canceling so that I have
a concrete understanding on the subject how it works. I also have
written a simple code that demostrate how noise canceling works and
trying to improve it in terms of code wirting.
You check out my rough draft and possibly the program on the assignment
page. (I am hoping to be able to post the programs because right now it
still has some errors in it)

I made some modification on the final papers draft, I also included a
simple program explaining how noise cancelation works in theory and
under ideal conditions. I will make some more addition to the programs
to make it more interesting.
