Pahuja, Sahil (2012) Designing an algorithm using active noise cancellation for development of a headphone in heavy noise industry. BTech thesis.
Noise pollution is a very big problem prevailing in the environment these days. The workers working in heavy noise industry gets affected by the high level of noise present in the industries.
The results may be as adverse as permanent hearing loss or even heart-attack. Here, I have tried to implement a few algorithms which can be used to develop a headphone which will cancel the noise from the environment. I have introduced various Active Noise Cancellation techniques or algorithms. I have discussed the LMS algorithm, the Filtered-x LMS algorithm, FLANN Filter and Particle Swarm Optimization (PSO) Algorithm. I have shown their behaviour in presence of linear as well as non-linear noise environment and discussed the application of each under various circumstances.
