Effect of high pitch sound causing loss of threshold of hearing

Sound refers to audible sound unless otherwise classified. A reasonably standard definition of audible sound is that it is a pressure wave with frequency between 20 Hz and 20, 000 Hz and with an intensity above the standard threshold of hearing In addition to its remarkable sensitivity, the human ear is capable of responding to the widest range of stimuli of any of the senses. Hearing range usually describes the range of frequencies that can be heard by human. In the present work sampling of testing human ear under different age group is taken and statistical conclusion drown about the threshold of hearing damage in the presence of noise and sound pollution. The sampling data is available for teenage group. The sampling is done in presence of sound pollution, with 3 hours
