Noise Reduction Techniques and Algorithms For Speech Signal Processing

Abstract

Acoustic problems in the environment have gained attention due to the tremendous growth of technology Exposure to high decibels of sound proves damaging to humans from both a physical and a psychological aspect. The problem of controlling the noise level in the environment has been the focus of a tremendous amount of research over the years. This paper describes a study of techniques for noise reduction which can be applied at the input to standard receivers trained on noise-free speech. In this review, we have classified the existing noise cancellation schemes and algorithms
