Abstracts: Acoustics is the science and technology dealing with sound. Noise is defined as undesirable or unwanted sound. It is our common experience that any mechanical system produces sound which becomes noise when it is undesirable or unwanted. It is known that high noise levels can be annoying or detrimental to health. The noise pollution in our ambient environment is due to the high noise levels coming from sources such as transportation vehicles, machinery, etc. Engineering approaches have to be used to either reduce or control the noise. The engineering methods deal with design of noise control devices such as mufflers, enclosures, vibration isolation mounting, resonators, etc.
