Dentists are at risk of noise-induced hearing loss (NIHL). Dental treatment equipment has high-intensity noise levels. Occupational levels multi-unit dental clinic higher than private and further increased NIHL. This study aims to develop a noise-reducing appointment system in clinics using duration steps noisemap. Restorative, periodontal, prosthetic procedure were measured clinic. A map was c...

Pathologic mechanisms in cochleae immediately following the onset of noise-induced hearing loss (NIHL) remain unclear. In this study, mice were exposed to 120 dB octave band noise for 2 h induce NIHL. Three hours after exposure, expression levels whole mouse genome analyzed by RNA-seq and DNA microarray. Differentially expressed genes (DEGs) exhibiting >2-fold upregulation or downregulation noi...

Mouse models are key tools for studying cochlear alterations in noise-induced hearing loss (NIHL) and for evaluating new therapies. Stimuli used to induce deafness in mice are usually white and octave band noises that include very low frequencies, considering the large mouse auditory range. We designed different sound stimuli, enriched in frequencies up to 20 kHz ("violet" noises) to examine th...

Prolonged exposure to noise over a period of years generally causes permanent damage to the auditoiy nerve and/or its sensory components. This irreversible damage, known as noise-induced hearing loss (NIHL), is the most common occupational disease in the United States today. Workers suffering from NIHL have difficulty understanding human speech and hearing other workplace cues. Despite the use ...

Noise overexposure may induce permanent noise-induced hearing loss (NIHL). The cochlear nucleus complex (CNC) is the entry point for sensory information in the central auditory system. Impairments in gamma-aminobutyric acid (GABA)-mediated synaptic transmission in the CNC have been implicated in the pathogenesis of auditory disorders. However, the role of protein kinase C (PKC) signaling pathwa...

Introduction Estimation of the incidence of noise-induced hearing loss sustained in the course of current operations requires both preand post-deployment pure tone audiometry. In a study of reserve personnel who deployed to Operation Herrick 6, 10% of personnel had good audiometric evidence to support a diagnosis of noise-induced hearing loss and a further 32% had audiograms that suggested it1....

BACKGROUND Noise-induced hearing loss (NIHL) from prolonged occupational exposure to noise continues to rank among the top worldwide work-related ill-health problems. AIMS To provide an overview of incident cases based on work-related audiological ill-health data collected over a 9-year period from occupational physicians (OPs), audiological physicians (APs), general practitioners and otorhin...

Previous studies and research efforts have shown that noise-induced hearing loss (NIHL) is a problem in the U.S. mining industry. In response, researchers at the National Institute for Occupational Safety and Health (NIOSH) have been conducting a cross-sectional survey of equip­ ment noise and worker noise exposures in the mining industry to estimate the potential for NIHL within the mining com...
