P17347: Active Noise Cancellation
/public/

Home

Project Summary Project Information

Cubicle-style office environments are often not conducive to focused, solitary work because of the noise generated by other employees. This leaves a great opportunity for a productivity increase by eliminating the distracting noises of an office environment through the use of an active noise cancellation system. An active noise cancellation system consists of a microphone, speaker, and processing software (most likely by means of a computer) and is used to reduce the overall noise in an environment. The real time noise cancellation will allow for improved efficiency of office workers due to the absence of ambient auditory distractions. The system should use speakers and microphones already existing in office computers for data collection and operate in near real time. Currently, the basis for this project is the SPEA2 algorithm used in conjunction with a phase array based system for operation.

The goals of this project are to reduce the overall noise of the work environment within the bandwidth of the average human hearing capabilities in real time with minimal adjustments from the user. The expected result is a functional prototype consisting of a specialized algorithm based on the SPEA2 that is able to operate on a typical laptop speaker and microphone in order to reduce the noise of the current environment. The resulting design needs to align with project goals and serve as a functional prototype for backers to demonstrate feasibility for a possible consumer product.
