Orthopaedic theatre can be noisy. Fifty percent of orthopaedic theatre staff have features of noise-induced hearing loss (NIHL). In this study, decibel (dB) levels were recorded in 17 total knee replacements (TKRs) and 11 total hip replacements (THRs). Noise levels reached 105.6dB(A) using a hammer and 97.9dB(A) with an oscillating saw. Exposure to levels above 90dB (which occurred in every case) even for short time periods is proven to cause irreversible loss of hearing. Tools used in orthopaedic theatre produce impulse noises that can cause NIHL...

The knowledge of mechanisms responsible for acquired sensorineural hearing loss in children, such as viral and bacterial infections, noise exposure, aminoglycoside and cisplatin ototoxicity, is increasing and progressively changing the clinical management of affected patients. Viral infections are by far the most relevant cause of acquired hearing loss, followed by aminoglycoside and platinum derivative ototoxicity; moreover, cochlear damage induced by noise overexposure, mainly in adolescents, is an emerging topic...

Hearing and cognition are commonly involved in both normal and pathological aging. Current clinical interest lies in whether peripheral hearing loss promotes cognitive decline. In our previous publication, the authors have shown a causal relationship between hearing and cognitive impairments in C57BL/6 mice. Here we extended the follow-up to 12 months to determine the long-term effects of hearing loss on cognition and to observe hippocampal p-tau and lipofuscin. One month old male mice were randomly allocated into two groups, the control (n = 12) and noise-induced hearing loss (NIHL) (n = 12)...

With rapid urbanization and life style changes, loud noise is omnipresent and has become a part of life. Indoor and outdoor environmental noise pollution have been documented as a serious health hazard with increasing adverse effects on fetus, infants, children, adolescents and adults. Noise induced hearing loss and non-auditory adverse effects due to noise pollution, are being increasingly diagnosed in all age groups including the fetus. Outdated motorized vehicles, machinery, increasing traffic, congested residential areas, crowded educational institutions and workplaces, unregulated commercial and industrial noise have become a source of noise pollution with long-term disability...

This study investigated to which extent the primary auditory cortex of young normal-hearing and mild hearing-impaired aged animals is able to maintain invariant representation of critical temporal-modulation features when sounds are submitted to degradations of fine spectro-temporal acoustic details. This was achieved by recording ensemble of cortical responses to conspecific vocalizations in guinea pigs with either normal hearing or mild age-related sensorineural hearing loss. The vocalizations were degraded using a tone vocoder...

BACKGROUND: Noise-induced hearing loss (NIHL) is a complex, irreversible disease caused by the interaction of genetic and environmental factors. In recent years, a great many studies have been done to explore the NIHL susceptibility genes among humans. So far, high powerful detections have been founded that genes of potassium ion channel genes (KCNQ4 and KCNE1), catalase (CAT), protocadherin 15 (PCDH15), myosin 14 (MYH14) and heart shock protein (HSP70) which have been identified in more than one population may be associated with the susceptibility to NIHL...

OBJECTIVE: Noise has been recognized as a major cause of cochlear damage resulting in both tinnitus and hearing loss. On the other hand, damage to the vestibular system, especially the saccule, can be considered as a potential problem. The cervical vestibular-evoked myogenic potentials (cVEMPs) have been established as a clinical test of measuring both sac-cular and inferior vestibular nerve function. Therefore, it is thought to be sensitive to the noise-induced damage to the vestibular system...

Hearing conservation programs (HCPs) mandated by the US Occupational Safety and Health Administration (OSHA) cost about $350/worker/year. Are they cost-effective? A cross-sectional model of the US adult population with and without HCPs incorporates (1) the American Medical Association's method for estimating binaural hearing impairment and whole-person impairment; (2) the model of the International Organization for Standardization (ISO) for estimating both age-related and noise-induced hearing loss; and (3) an acceptable cost of $50,000 per quality-adjusted life year...

Noise induced hearing loss (NIHL), a multifactorial disease involving both genetic and environmental factors, is one of the most important occupational health hazards. Nonetheless, the influence of FOXO3 variants on NIHL risk have not been illuminated. This research was conducted to explore the effects of FOXO3 polymorphisms on individual susceptibility to NIHL. A total of 2689 industrial workers from one textile factory of east China were recruited to participate in the current research. Venous blood was collected, questionnaire and pure-tone audiometry (PTA) was conducted by specialist physicians...

Noise is an important socioeconomic problem in industrialized countries. Development of efficient treatment options for the audiological phenomena resulting from noise-induced hearing loss requires in-depth understanding of the underlying damage mechanisms causing peripheral and central nervous changes. Mechanical damage, ischemia and excitotoxicity are mainly responsible for noise-induced cell death and biophysical changes in the cochlea. Auditory synaptopathy is an additional consequence. Besides these cochlear pathologies, noise exposure leads to extensive changes within the central auditory pathway...

A new noise regulation for the mining industry became effective in 2000, providing a consistent regulatory requirement for both coal and non-coal mining divisions. The new rule required mines to implement hearing conservation programs, including a system of continuous noise monitoring, provision of hearing protection devices, audiometric testing, hearing loss training, and record keeping. The goal of this study was to assess hearing conservation program compliance, and excessive noise exposure and hearing loss risks for both coal and non-coal mining divisions through evaluating MSHA citations...

Chronic tinnitus is a prevalent hearing disorder, and yet no successful treatments or objective diagnostic tests are currently available. The aim of this study was to investigate the relationship between the presence of tinnitus and the strength of the middle-ear-muscle reflex (MEMR) in humans with normal and near-normal hearing. Clicks were used as test stimuli to obtain a wideband measure of the effect of reflex activation on ear-canal sound pressure. The reflex was elicited using a contralateral broadband noise...

BACKGROUND: Recent studies have evaluated the associations between polymorphisms of the heat-shock protein 70 (HSP70) encoding genes and noise-induced hearing loss (NIHL). However, the conclusions of these studies are conflicting. The objective of this meta-analysis was to clarify the association between all known polymorphisms of HSP70 genetic loci and susceptibility to NIHL, based on existing reports. METHODS: We conducted a meta-analysis of the association between Hsp70 polymorphisms (rs1043618, rs1061581, rs2075800, rs2227956, and rs2763979) and NIHL risk in both Chinese and Caucasian males...
