Adjusting retrospective noise exposure assessment for use of hearing protection devices
Earlier retrospective noise exposure assessments for use in epidemiological research were not adequately characterized because they did not properly account for use of hearing protection devices (HPD) which would result in potential misclassification. Exposure misclassification has been shown to …

Modeling the effects of aircraft flight track variability on community noise exposure
… concentration also creates a concentration of noise impacts on the communities surrounding airports, which has led to an increase in noise complaints at many airports that have implemented these routes. In order to understand these changes in noise, and to design procedures that could help …

Using serious games to prime safety students for occupational noise exposure risk assessment
… to enhance the training for occupational noise risk assessments. A simulator titled AssessVR, a PC-based application was created to enhance the learning experience of students and safety workers in identifying hazards and assessing risks. This simulator enables students to engage in hazard …

Aircraft noise exposure trends and impact on cardiovascular health in the United States
Aircraft noise is a considerable environmental stressor for communities surrounding airports. There is also growing interest in the relationship between noise and health outcomes as exposure has been associated with physiological and psychological effects. Yet the extent to which aircraft noise …

The effects of noise exposure and genetic background on auditory-evoked behaviors in larval zebrafish
… by extrinsic factors, such as environmental noise, and intrinsic factors, such as genes and arousal. How do these factors interact and influence auditory-related behaviors? I addressed this question in the larval zebrafish (Danio rerio). Zebrafish have been a powerful genetic model species …

The Effects of Occupational Ultrasonic Noise Exposure on Hearing in Dental Hygienists: A Pilot Study
… was to determine whether long-term ultrasonic noise exposure via the dental office environment is related to dental hygienists' hearing status. Registered dental hygienists (N = 698) who live in the Hampton Roads area were mailed a <em>Dental Hygiene Work History Questionnaire</em>to determine …

Repurposing Oseltamivir, a Commonly Prescribed Influenza Antiviral, for the Prevention of Noise- and Cisplatin-Induced Hearing Loss
… delivery in multiple established cisplatin and noise exposure mouse models. The drug conferred permanent hearing protection of 15-25 decibel Sound-Pressure Level (dB SPL) for both female and male mice. In mice, oseltamivir treatment reduced outer hair cell death after cisplatin treatment and …

Auditory Hair Cell Regeneration and Gene Expression in Noise-Exposed Zebrafish (Danio rerio)
… sensory hair cells in the inner ear after exposure to excessive noise. However, a time course of auditory hair cell regeneration has not been characterized for zebrafish, nor has gene expression following noise exposure. To establish a time course of hair cell regeneration, adult zebrafish …

D-METHIONINE (D-MET) MECHANISMS UNDERLYING OTOPROTECTION FROM NOISE- AND AMINOGLYCOSIDE-INDUCED HEARING LOSS
… (D-met) has demonstrated otoprotection from noise-, aminoglycoside-, and cisplatin-induced hearing loss in animal studies. As a result, D-met is currently progressing through translational "bench to bedside" research. However, D-met's exact otoprotective mechanisms have not been fully …

Echolocation-based foraging by harbor porpoises and sperm whales, including effects of noise and acoustic propagation
… behavior, including assessment of the effects of noise on foraging behavior and the potential influence of ocean acoustic propagation conditions on biosonar detection ranges and whale noise exposure. In addition to presenting some novel basic science findings, the case studies presented in this …

Noise Levels in a South African bank cash centre
Noise induced hearing loss remains a concern within the employment sector, in spite of the preventability there of. In order to effectively prevent this debilitating disorder the risks need to be fully understood. One such area that requires investigation is the cash centres within the financial, …

Interactive effects of developmental PCB exposure and relevant environmental risks on the auditory system
… the developing offspring. Developmental PCB exposure has been shown to cause auditory deficits that last through adulthood. We assessed the interaction of PCBs with other environmental risks to examine if there were additive or interactive effects on auditory function. Rats were exposed …

Comparison of methods for evaluating impacts of aviation noise on communities
Community opposition to the noise concentration from precise NextGen Performance-Based Navigation (PBN) aircraft arrival and departure procedures poses a significant threat to the future of these procedures in the U.S. National Airspace System. A substantial number of complaints concerning airport …

Geometry optimization of dry ice blasting nozzle for the noise reduction using experimental validation
… of dry ice blasting (DIB), it produces a high noise exposure. The noise exposure during a high blasting pressure may reach up to 130 dB which is considered a harmful noise level (standard 90 dB for eight working hours per day). At present, safety measures are taken according to administrative …

Developing a framework of non-fatal occupational injury surveillance for risk control in palm oil mills
… NFOI surveillance by using epidemiological data, noise exposure data and NFOI data among palm oil mills’ workers. A total of 420 respondents who assigned in operation and processing areas (OP) (n=333) and general or office workers (n=87) had voluntary participated in this research. A questionnaire …

Hear Today, Gone Tomorrow: Exploring Quinoxaline Derivatives as a Treatment for Noise-Induced Hearing Loss
… around the world living with some degree of noise-induced hearing loss (NIHL) and 1 billion young adults at risk of developing NIHL. Currently, there are no FDA-approved drugs that protect the inner ear against NIHL. To address this need, my thesis aims to investigate the therapeutic …
