Noise Cancelling Headphones by Niko Bhatia

The goal of this project is to build a pair of noise cancelling headphones that incorporate active and passive noise cancellation. The three main steps to this project are building the active noise cancellation circuit, designing and building the wooden headphones, and combining the noise cancellation circuit with the headphones. The passive noise cancellation effectively blocked out the ambient noise at the Maker Faire, and the active noise cancellation blocked out frequencies up to 2kHz, which is in the frequency range of an airplane engine.
