Book excerpt: After the early success of some articles as author and co-author, Dr Win Tin has come up with his first book on Noise-Induced Hearing Loss and the Hidden Society Burden. He noticed that everyone needs peace of mind, especially after a long working day. We need to rest, physically and mentally to recoup, working again with enthusiasm the next day. Thus, it is important that we have a certain private, quiet, peaceful serene environment, day or night. But noise is all around us. The sound of grass cutters, the piling of structures nearby, children playing and shouting, or the traffic noise. These can make a lot of noise and the peace shattered. Noise-induced hearing loss is mainly caused by a certain amount of noise which has a deleterious effect on the ear when exposed to long periods of time e.g. years, and usually without the person noticing, as in occupational noise-induced hearing loss or single instances of extreme noise, as in acoustic trauma. This causes not only hearing loss but effects socially, financially, physically and mentally. Its problem is so big with compensation in millions, causing a huge hidden burden to the society, people and government. Yet it should be noted that this is the only preventable cause of sensorineural hearing loss, which can be prevented, while other causes are still not possible. The book introduces various noise, the pathogenesis and causes of noise-induced hearing loss, as seen in various strata of people. Apart from this, there is the Malaysian perspective as written by some researchers from Malaysia. Then there are also effects of noise not only on humans but also in birds and fish. Methods to diagnosis and ways to prevent, with up-to-date researches and treatment are also discussed. Thus, it is a comprehensive one for the knowledge of all levels, professionals and non-professionals. This book is important, and everybody should read or keep as a reference, as they will know in-depth, as most are unaware of the hidden problem. Young people, military, hospital workers, nurses, contractors, builders, architect, engineers, urban planners, public health doctors and everyone can benefit from this book. Hence, this book is useful not only for leisure reading but cherished for life. With the 25th anniversary of UMS, this book can be a milestone, for the wellness of UMS staff and people of Sabah.

Available in PDF, EPUB and Kindle. Book excerpt: Exposure to loud noise continues to be the largest cause of hearing loss in the adult population. The problem of NIHL impacts a number of disciplines. US standards for permissible noise exposure were originally published in 1968 and remain largely unchanged today. Indeed, permissible noise exposure for US personnel is significantly greater than that allowed in numerous other countries, including for example, Canada, China, Brazil, Mexico, and the European Union. However, there have been a number of discoveries and advances that have increased our understanding of the mechanisms of NIHL. These advances have the potential to impact how NIHL can be prevented and how our noise standards can be made more appropriate.

This book was released on 2020-04-24 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing industry is one of the most important sectors that contribute significantly to the economy of Malaysia. More than half a million workers in Malaysia work in this industry and many of them are exposed to loud noises of more than 85dB that is harmful to health. Noise induced hearing loss (NIHL) is the highest reported occupational disease affecting around 16% of workers globally. In this book, we reported a study conducted in 26 manufacturing industries that employed around 270,000 workers with more than 40% of them were exposed to noises that potentially cause NIHL. This cross-sectional study designed with face-to-face interviews using questionnaires conducted among Occupational Safety and Health practitioners and workers selected from these industries. Direct and indirect cost was imputed component covering cost of medical care and rehabilitation, transportation, loss of productive time and investigations. Costing data in the government hospital was obtained from casemix information system from a tertiary teaching hospital. The study confirmed that NIHL among workers in manufacturing industry imposed a huge economic burden for Malaysia. In order to mitigate this problem, the existing and yet out-dated noise regulation need to be reviewed. Meanwhile employers need to implement hearing conservation program more effectively.

This book was released on 2014-02-19 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Occupational Safety and Health Act of 1970, Congress declared that its purpose was to assure, so far as possible, safe and healthful working conditions for every working man and woman and to preserve our human resources. In this Act, the National Institute for Occupational Safety and Health (NIOSH) is charged with recommending occupational safety and health standards and describing exposure concentrations that are safe for various periods of employment-including but not limited to concentrations at which no worker will suffer diminished health, functional capacity, or life expectancy as a result of his or her work experience. By means of criteria documents, NIOSH communicates these recommended standards to regulatory agencies (including the Occupational Safety and Health Administration [OSHA]) and to others in the occupational safety and health community. Criteria documents provide the scientific basis for new occupational safety and health standards. These documents generally contain a critical review of the scientific and technical information available on the prevalence of hazards, the existence of safety and health risks, and the adequacy of control methods. In addition to transmitting these documents to the Department of Labor, NIOSH also distributes them to health professionals in academic institutions, industry, organized labor, public interest groups, and other government agencies. In 1972, NIOSH published Criteria for a Recommended Standard: Occupational Exposure to Noise, which provided the basis for a recommended standard to reduce the risk of developing permanent hearing loss as a result of occupational noise exposure [NIOSH 1972]. NIOSH has now evaluated the latest scientific information and has revised some of its previous recommendations. The 1998 recommendations go beyond attempting to conserve hearing by focusing on preventing occupational noise-induced hearing loss (NIHL). This criteria document reevaluates and reaffirms the recommended exposure limit (REL) for occupational noise exposure established by the National Institute for Occupational Safety and Health (NIOSH) in 1972. The REL is 85 decibels, A-weighted, as an 8-hr time-weighted average (85 dBA as an 8-hr TWA). Exposures at or above this level are hazardous. By incorporating the 4000-Hz audiometric frequency into the definition of hearing impairment in the risk assessment, NIOSH has found an 8% excess risk of developing occupational noise-induced hearing loss (NIHL) during a 40-year lifetime exposure at the 85-dBA REL. NIOSH has also found that scientific evidence supports the use of a 3-dB exchange rate for the calculation of TWA exposures to noise. The recommendations in this document go beyond attempts to conserve hearing by focusing on prevention of occupational NIHL. For workers whose noise exposures equal or exceed 85 dBA, NIOSH recommends a hearing loss prevention program (HLPP) that includes exposure assessment, engineering and administrative controls, proper use of hearing protectors, audiometric evaluation, education and motivation, recordkeeping, and program audits and evaluations. Audiometric evaluation is an important component of an HLPP. To provide early identification of workers with increasing hearing loss, NIOSH has revised the criterion for significant threshold shift to an increase of 15 dB in the hearing threshold level (HTL) at 500, 1000, 2000, 3000, 4000, or 6000 Hz in either ear, as determined by two consecutive tests. To permit timely intervention and prevent further hearing losses in workers whose HTLs have increased because of occupational noise exposure, NIOSH no longer recommends age correction on individual audiograms.

Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Available in PDF, EPUB and Kindle. Book excerpt: "Objective: To develop a business case that promotes adoption of noise controls by reducing barriers to industry acceptance and enhancing drivers that foster their implementation. Background: Over 75% of the U.S. mining workforce is exposed to hazardous noise, putting them at risk of noise-induced hearing loss (NIHL). Consequently, coal miners suffer high rates of hearing impairment that increase to 70%-90% by retirement age. To address the noise problem for coal miners, researchers from the National Institute for Occupational Safety and Health (NIOSH) first determined that the continuous mining machine (CMM) ranked first among machines associated with reported coal noise overexposures. Further studies found that most CMM noise is generated by three component systems on the machine: dust collection, cutting, and conveying. Of these systems, the on-board chain conveyor was found to be a dominant noise source. Noise generated by the conveying system was addressed through the development of a urethane-coated flight bar chain. The coated chain, shown in Figure 1, has demonstrated an 8-hour time-weighted average (TWA) reduction of operator exposure by 3 dB(A). It has since been accepted by the Mine Safety and Health Administration (MSHA) as a "technologically achievable" noise control for CMM operators who are exposed to noise that exceeds the MSHA permissible exposure level. Having demonstrated the noise reduction performance of the coated chain, NIOSH has assembled information into a business case that can be used by operations considering adopting the chain at their worksite. Business Case: A business case is often used in organizations to assist rational decision-making about major initiatives. It facilitates systematic consideration of financial, organizational, and market perspectives. For occupational health and safety initiatives involving control technologies, a business case can encompass financial and organizational concerns alongside long-term health and safety outcomes. Although NIOSH and its partners have developed control technologies to reduce mine workers' overexposure to noise, implementation at the workplace has been impeded by slow industry acceptance and buy-in. Some of the slowness is due to a lack of readily available information needed to move forward with implementation. In some cases, there are real or perceived barriers. These are addressed below, followed by several drivers that can accelerate implementation of noise controls. Barriers: Financial expense: The perception that a noise control will increase costs is often used to defer investment in a control that might otherwise reduce health and safety risks. NIOSH worked with its industry partners when developing the coated chain to minimize any cost premium. The urethane-coated 38-inch conveyor chain produced by industry partner Cincinnati Mine Machinery costs 46% more than a standard single-sprocket chain. As demand and sales increase, the additional production volume may allow the company to reduce the cost further until it is comparable to that of a standard chain. These cost differences may be offset through long-term gains in lowered workers' compensation costs and insurance premiums related to noise-induced hearing loss. Unfamiliar maintenance: The negative perception of new or different maintenance procedures may inhibit companies from switching chains. In working with the chain manufacturer, NIOSH found that the urethane-coated chain does not require any new or unusual maintenance procedures that differ from the manufacturer's standard processes. Adhering to standard maintenance procedures (e.g., ensuring chain tension) will keep the urethane coating from wearing prematurely. Unfamiliar installation: Even though the urethane-coated chain will fit on any CMM that has a standard 38- or 30-inch conveyor system, there may be a perception that chain installation will change. During field testing, NIOSH research found there were no differences between installing a standard or a coated chain. The urethane-coated flight bar chains are engineered as a direct replacement that requires no modification of the machine. Variable conditions: Coal mine conditions can be highly variable, and there may be concerns that the urethane-coated chain cannot hold up in the more extreme conditions. To address these concerns, the coated chain was tested in the harshest conditions that could be found. It was placed in construction development and production sections that encounter exceptionally high wear and impact loads, including mining and conveying solid rock and construction debris. The coated chain worked successfully in these sections despite the harsh conditions. Durability: New technologies or equipment often prompt questions about whether they are as durable as the current technology or equipment. For the urethane-coated chain, these questions centered on whether it has the same chain life as a standard single-sprocket, noncoated chain. The coated chain was field-tested in three U.S. mines in a wide variety of mining conditions. At these mines, the urethane-coated chain had the same replacement rate as the standard noncoated chain, meeting or exceeding the mines' expectations. Drivers: Safety: Studies that investigated the link between noise and safety have found that workers whose daily noise exposures exceed 90 dB(A) have higher rates of single and multiple accidents. The risk is elevated for workers with normal hearing and is even higher for workers who have a hearing loss. Noise controls like the urethane-coated chain that reduce noise exposure can therefore also have a safety benefit. Lower noise exposure: Another form of risk is the increased likelihood of a noise-induced hearing handicap or impairment. A NIOSH-developed model shows that a 65-year-old worker with 10 or more years of exposure will have a higher likelihood of a hearing impairment with higher average noise exposures (Table 1). So, for example, if the exposure can be reduced from 94 to 90 dB(A), 11 fewer workers out of 100 would acquire a noise-induced hearing impairment. Lower stress: Reducing the noise exposure of CMM operators through the use of a urethane-coated chain will have an added benefit of lower workplace stress. Noise has been found to be a stressor that can interfere with concentration, causing errors and accidents. Stress is also linked to certain illnesses that can worsen absenteeism, reduce productivity, and increase insurance costs. Lower workers' compensation costs: Workers' compensation insurance provides financial reparation to workers who sustain workplace injuries, fatalities, and occupational disease. The insurance companies make payments to the affected workers while the mining companies pay premiums to the insurers. The premiums a company has to pay can be indirectly affected by claims experience, along with other factors. During 2006-2009, the two most recognized workers' compensation insurance carriers for the U.S. coal mining industry received 92 claims filed for (nontraumatic) hearing loss compensation. Together, they paid nearly $750,000 in hearing loss claims. Summary: The goal of this research is to reduce mine workers' overexposure to noise and ultimately reduce the number of workers who suffer from NIHL. Using a business case model can overcome the barriers and concerns that delay industry acceptance and use of control technologies such as the urethanecoated chain. The coated chain is part of a suite of controls developed by NIOSH and others that can reduce worker overexposure to noise. By assembling information into a business case model to challenge the barriers to industry acceptance, NIOSH is working to promote adoption of effective engineering noise controls."--NIOSHTIC-2.

Abstract: Background: Noise is one of the most important forms of environmental pollution among developed and developing countries. A report from UK National Study of Hearing estimated that around 440 million people suffer from noise induced hearing loss in EU countries with 1-1.6 million disability-adjusted life year lost. In China, the Second China National Sample Survey on disability in 2007 revealed that about 27.8 million people suffered from hearing impairment, and 73.4% of which (about 20 million) were diagnosed with disability. The prevalence of hearing impairment was estimated to be 2.1% in the general population, and increased to 11.0% among those aged greater than 65 years. Objective: To find out the effect of earplug on noise induced hearing loss (NIHL), as well as understanding the source and exposure of noise in the industry, to estimate the prevalence of NIHL in factories with noise exposure, to analyze relationships between NIHL and age, sex, dose and duration of occupational noise exposure, type of work, use of hearing protection products, education level and other factors. Significant risk factors identified were used to provide evidence-based recommendations in prevention and control of NIHL. Study Design: Retrospective, cross-sectional study Method: A total of 1874 workers exposed to noise in a compressor factory in Guangzhou, China were included. Between September 2011 and January 2012, physical examination including a screening program of hearing loss, pure tone audiometry test were carried out among workers including information on age, sex, work types, noise exposure level, exposure time, as well as the questionnaire about earplug using status, status of using ear products report by company, smoking status, education level, discharge of ear, history of herpes zoster, history of using ototoxic drugs, history of ear surgery, family history of NIHL, systolic blood pressure, diastolic blood pressure. The outcome variable is the audiometric mean value which reflects hearing status of the subjects. Subgroup differences in mean value of audiometry were compared by independent sample t-test. Multiple linear regression and logistic regression models were used to evaluate associations between earplug use and NIHL, adjusted for other potential confounders. Factors associated with earplug use were also identified. Result: 1873 workers took part in the study (both physical examination and questionnaire) The prevalence of NIHL is 381 (20.3%) from study, and an average noise level of 83.5 dB was detected in the factory across different types of working place. The pure tone audiometric mean value (PTA) is 26.7 dB with a standard deviation of 4.8. The mean PTA value for those using earplug is 25.81 dB, which was significantly lower than those not using earplug with a mean PTA value of 1.54 dB (p Multiple linear regression model showed a dose response effect in use of earplug on NIHL, with an estimated mean PTA 1.49 dB (p-value
