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 …

The Role of the Mitogen Activated Protein Kinase Pathway in Cisplatin and Noise-Induced Hearing Loss
Hearing loss is one of the most common types of disability; however, there are few ways to combat it with only one FDA-approved drug to treat any type of hearing loss. Cisplatin, a commonly used chemotherapy agent, and exposure to loud noise are two main causes of hearing loss. There are many …

Hearing protection in mines : evaluating the Noise Clipper® custom made hearing protection device
Noise induced hearing loss has been extensively researched and commented on, yet it remains prevalent among industrial workers. The real-world attenuation properties of the Noise Clipper® custom-made hearing protection device and the comfort levels it afford are unknown. Furthermore, research in …

Emergency vehicle siren noise: A potential for hearing loss
… of this thesis was to critically investigate the noise produced by the sirens fitted to South Australian Police general patrol vehicles and calculate if this noise was of an intensity to cause noise induced hearing loss. Previous studies in Western Australia and in South Australia examined noise …

Intelligibility of synthesized voice messages in commercial truck cab noise for normal-hearing and hearing-impaired listeners
… of synthesized speech under a variety of noise conditions for both hearing-impaired and normal-hearing subjects. Modified Rhyme Test stimuli were used to determine intelligibility in four speech-to-noise (S/N) ratios (0, 5, 10, and 15 dB), and three noise types, consisting of …

Spatiotemporally-Resolved Velocimetry for the Study of Large-Scale Turbulence in Supersonic Jets
The noise emitted from tactical supersonic aircraft presents a dangerous risk of noise-induced hearing loss for personnel who work near these jets. Although jet noise has many interacting features, large-scale turbulent structures are believed to dominate the noise produced by heated supersonic …

Spectral attenuation and wearability of circumaural hearing protectors as influenced by design attributes and work-related activity
Hearing protection devices (HPDs), a widely used countermeasure against noise-induced hearing loss, are laboratory-tested for their attenuation (noise reduction) capabilities. Unfortunately, laboratory tests overestimate the in-workplace performance of the devices, potentially leading to inadequate …

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, …

Music Intensity in the Ear Canal in Quiet and in Subway Noise Using Four Different Headphones
<p><strong>Background</strong>: Noise-induced hearing loss, hearing loss caused by exposure to loud sounds, affects individuals of all ages. One cause of noise-induced hearing loss is listening to music at high intensities on personal listening devices, such as the iPhone. The aim of this study was …

An Ecological Approach to the Assessment and Promotion of Hearing Protection Behaviour in the Workplace
Background: Noise-induced hearing loss (NIHL) is a common debilitating occupational health problem in New Zealand and globally. In addition to the economic burden arising from compensation and rehabilitation for NIHL, quality of life is diminished. Unfortunately, interventions to prevent NIHL have …

Optimum Design of Compact, Quiet, and Efficient Ventilation Fans
… fans are one of the most harmful sources of noise due to their close proximity to occupied areas and widespread use. The prolonged exposure to hazardous noise levels can lead to noise-induced hearing loss. Consequently, there is a critical need to reduce noise levels from ventilation fans. …

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 …

An In-Field Experiment on the Effects of Hearing Protection/Enhancement Devices and Military Vehicle Noise on Auditory Localization of a Gunshot in Azimuth
Noise-induced hearing loss and tinnitus are the two most prevalent service-connected disabilities for veterans receiving compensation (Department of Veterans Affairs, 2010). While it is possible to protect against noise-induced hearing damage with hearing protection devices (HPDs) and hearing …

The Turbulence Structure of Heated Supersonic Jets with Offset Total Temperature Non-Uniformities
Noise induced hearing loss is a large concern for the Department of Defense. Personnel on aircraft carriers are exposed to dangerous noise levels of noise from tactical aircraft, causing hearing damage which results in significant costs for medical care and treatment. Additionally, NASA and the FAA …

Noise Levels In The Neonatal Intensive Care Unit: A Systematic Review
… of this systematic review is to investigate noise levels in the Neonatal Intensive Care Unit (NICU) in order to see if they are in compliance with the American Academy of Pediatrics (AAP) proposed standards. This investigation also aims to compare noise levels among various NICU conditions in …

Stability, LES, and Resolvent Analysis of Thermally Non-uniform Supersonic Jet Noise
For decades noise-induced hearing loss has been a concern of the Department of Defense (DoD). My research investigates noise generation and dispersion in supersonic jets and focuses on the fluid-dynamic regime typical of high-performance turbojet and turbofan engines. The goal of my research is to …

Effects of developmental PCB exposure on audiogenic and amygdala kindling models of seizure
… old rats that had previously been exposed to a noise induced hearing loss paradigm. Here, studies were conducted to assess the susceptibility to AGS in young adult rats following developmental PCB exposure alone (without loud noise exposure), and to determine if there was an underlying decrease …

Interactive effects of developmental PCB exposure and relevant environmental risks on the auditory system
… interaction of developmental PCB exposure and noise exposure during adulthood to evaluate whether early PCB exposure increased the susceptibility to noise-induced hearing loss (NIHL). Since PCBs are known to cause hearing deficits via outer hair cell (OHC) damage, and the OHCs protect the inner …

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 …
