Today technology and rapid industrialization has thrown up a new and rapidly spreading environmental pollutant – Noise. Nowadays, noise has become the most commonly encountered stressor in our daily lives. When noise intensity that we are exposed to exceeds 90dB, then it becomes a stressor. Depending on the frequency, intensity and duration of exposure noise affects the body in different ways. ...

Considerable information concerning the dynamical properties of the hearing mechanism can be obtained from physical measurements on audition. In fact, probably more precise information can be obtained by such measurements than from data obtained by animal experimentation, or from data on post mortem sections of human temporal bones. It is well known that when a person is immersed in, a noise hi...
