A Comparison Of Temporary Threshold Shifts In Dentists, Hygienists, And Dental Assistants, Sabina E. Ciaccio

Dissertations, Theses, and Capstone Projects

Objective: The purpose of this study is to compare the temporary threshold shifts (TTS) in dentists, hygienists, and dental assistants. The specific aim of this study is to compare the differences in temporary shifts caused by the different dental equipment and the proximity to the equipment. The current literature does not compare the change in hearing thresholds of dental personnel.

Methods: Dentists, dental assistants, and hygienists from Hermann Dental Associates will be given a case history form to determine inclusion status for this study. Exclusion criteria will include known hearing loss and significant noise exposure the day prior. …

Knowledge And Attitudes Towards Usage Of Hearing Protection In Volunteer Firefighters, Rachel S. Combs

Dissertations, Theses, and Capstone Projects

Background: Occupational noise-induced hearing loss (NIHL) represents a substantial global public health concern. Regulatory agencies such as the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupation Safety and Health (NIOSH) aim to establish noise exposure limits in occupational settings, yet certain professions, such as firefighting, remain at a heightened risk. Although research has been conducted on noise exposure and hearing protection in career firefighters, a lack of research exists on volunteer firefighters. The purpose of this study was to 1) establish the extent that volunteer firefighters are currently educated on hearing conservation and hearing protection 2) …

Practices And Attitudes Towards Infant Hearing Protection At Orthodox Jewish Weddings, Rebecca Weiss

Dissertations, Theses, and Capstone Projects

Previous research has shown that prolonged exposure to noise can cause permanent hearing loss no matter what age, including infants. The impact of noise at orthodox Jewish weddings, where infants are frequently in attendance, can reach extremely high and damaging levels of sound intensity. Because the hearing conservation behaviors and attitudes towards child hearing protection in this population are unknown, the objective of this study is to identify the attitudes and behaviors of orthodox Jewish wedding attendees toward child hearing conservation. A survey was developed and administered electronically to congregants of orthodox Jewish synagogues in the New York City area. …

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 Dose Reduction Via Behavior Modification Using In-Ear Dosimetry Among Usaf Personnel Exposed To Continuous Impulse Noise, Jesse A. Trawick

Theses and Dissertations

The purpose of this research was to investigate the use of in-ear noise dosimetry and worker feedback to reduce noise exposures among combat arms instructors and heavy equipment operators in the Air Force. Specifically, this thesis sought to determine how effectively hearing protection devices (HPDs) are being utilized currently, and whether providing at-ear noise exposure data to workers results in reduced noise exposures or changes in worker attitude. These questions were addressed by performing a six-month field study using dosimeters to record worker noise exposures under HPDs. Subjects served as their own control, receiving feedback in only the latter half …

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 …
