Occupational Noise Exposure Evaluation Of Airline Ramp Workers, Adekunle Ogunyemi

USF Tampa Graduate Theses and Dissertations

Noise exposure is a common hazard to workforce in general although at varying degrees depending on the occupation, as many workers are exposed for long periods of time to potentially hazardous noise.

Every year, twenty-two million workers are exposed to potentially damaging noise at work. In 2015 U.S. businesses paid over $1.5 million in penalties for not protecting workers from noise. (OSHA, 2016). There may be a direct or indirect consequence of the possibilities of overexposure to noise notwithstanding the compulsory hearing protection requests for the occupations with potential hazards, and these exposures usually arise from the various types of …

Occupational Noise Exposure Evaluation Of A Group Of Groundskeepers At A University Campus, Monica Elisa Garcia

USF Tampa Graduate Theses and Dissertations

Every year, twenty-two million workers are exposed to potentially damaging noise at work. Last year, U.S. businesses paid more than $1.5 million in penalties for not protecting workers from noise. (OSHA, 2016). In the United States ten million people have some kind of noise related hearing loss (CDC, 2016) and noise damage to the ear may not be detected until it is great enough to cause hearing impairment.

Grounds keeper’s functions consist of a variety of activities that require the use of powered tools such as mowers, riding mowers, leaf blowers, pressure washers, trimmers/edgers and chainsaws. OSHA has stated that …

Sound Attenuation Performance Of Fiber-Reinforced Polymer Composite Circumaural Hearing Protection Devices, Steven Christopher Augustine

USF Tampa Graduate Theses and Dissertations

Personnel who work on the flight deck of an aircraft carrier are exposed to extreme levels of jet engine noise often in excess of 140 decibels (dB). The current circumaural hearing protective devices (CAHPD) employed by flight deck crewmen are inadequate for the level of protection required for these extreme levels of noise. Fiber-reinforced thermoset polymer composite (FRPC) materials such as aramid fibers used in body armor, have high theoretical values of acoustic impedance due to a fundamentally high modulus of elasticity and may offer a superior level of hearing protection over original equipment (OE) thermoplastic CAHPDs. The objective of …
