Developed societies experience an increased level of noise pollution. A Sound Cancellation project was incorporated into a 2 hour-credit Electronics Specials Problems course. The active control of sound is a solution by making an anti-noise for every known noise volume. The antinoise signal will cancel itself along with the noise. A computer runs an adaptive noise control algorithm in assembly code. The program takes input and determines the corresponding value for a cancellation sound output of analog to digital and digital to analog conversions with sine wave and sound 8-bit I/O.
