Adverse effect of using headphone

Abstract

Apart from the frequency, the length of the sound exposure is a major factor in the injury to the ear. Simply specified, louder sounds will cause much less visibility and more harm. Employers provide hearing aid for workers with an average exposure of 85 dB for over 8 hours, as mandated by the Occupational Health & Safety Administration (OSHA). Although this feels like a long while, headphones can do harm in less than an hour with only marginally greater sound levels, and music can be easily imagined with headphones lasting one or more hours.
