According to Statistics Canada, more than one million Canadians suffer from hearing problems – and it’s not just older demographics. A study published in the Journal of the American Medical Association showed an increase in hearing loss to 19.5% from 15% between the mid-1980s to 2006. Because there are several different types of hearing loss, it’s important to get tested at a qualified hearing centre as soon as symptoms appear.
According to the Canadian Association of Speech-Language Pathologists & Audiologists (CASLPA), noise-induced hearing loss is 99% preventable if proper hearing protection is used. Ear muffs – These fit over the ears and provide great protection without requiring a customized fit. Custom earplugs – These offer very good protection but will require an appointment with an audiologist to make a custom earmold impression.
Left untreated, hearing loss can have detrimental effects, including speech and language impairments, employment challenges and reduced household income. Digital hearing aids – These are usually an integral part of aural rehabilitation and help people readjust to processing a fuller spectrum of sound.
Assistive listening devices – These may be used with or without hearing aids and help people in specific situations such as using the telephone or listening to the TV. Cochlear implants – Some people who are profoundly hard of hearing and who don’t benefit from hearing aids may be candidates for this type of surgery.

Researchers from the University of Pittsburgh School of Medicine say that they are close to finding a way to prevent tinnitus, the most common symptom associated with noise-induced hearing loss. Such a medication could be a very helpful preventive strategy for those who work in situations where exposure to very loud noise is likely. According to the latest statistics made available by Action on Hearing Loss, there are more than 10 million people in the UK with some form of hearing loss, where 1 in 10 adults have tinnitus (1). The study, whose abstract is published in the online version of the Proceedings of the National Academy of Sciences, reveals for the first time the reason tinnitus occurs (2).
The researchers conducted experiments that exposed mice to a 116 decibel sound in one ear for 45 minutes, which eventually led to the development of tinnitus in fifty percent of exposed mice.
Those who have been experiencing tinnitus as a result of a noisy workplace should not hesitate to report their medical condition to their employer and visit their GP. Asons Solicitors is a Bolton-based law practice that specialises in personal injury and industrial disease claims.

Hearing loss can be attributed to natural disease and aging, but also to external factors, which means hearing damage can be preventable.
The extent of this type of hearing damage depends on the intensity of the noise and the length of exposure. Many individuals choose not to wear hearing protection because it may interfere with effective communication in the workplace or it may be uncomfortable.
Measures of localization performance included: (1) percentage correct localization, (2) percentage of right--left localization errors, (3) percentage of front-rear localization errors, and (4) localization absolute deviation in degrees from the alarm's actual location. This training was paired with audiometry and counseling and a survey of attitudes and beliefs in hearing loss prevention. Naive subjects were recruited and tested using three different forms of training: written, video, and individual training. Farmers are frequently exposed to excessive noise, ranking among the top three occupations and industries with the highest risk for hearing loss. Because the role of the HPD in prevention of hearing loss remains as a vital last line of defense against the effects of noise exposure, proper assessment of their performance is increasingly critical. This makes it difficult to properly assign hearing protectors when one wishes to closely match attenuation to actual exposure. For better hearing conservation, it is important to identify and eliminate the causes for the low motivation to use hearing protection. The results indicate that this type of HP is well accepted by experienced users, particularly so, by those who appreciate reliable communication while wearing the devices. Tinnitus is a medical condition which makes sufferers perceive a ringing noise in one or both ears and it is mainly caused by exposure to loud noise such as a noisy work environment.
Associate professor Thanos Tzounopoulos of the Pittsburgh School of Medicine said he and his team treated mice with a federally approved epilepsy drug while exposing them to loud noises.


They discovered that those treated with an epilepsy drug called retigabine immediately after being exposed to noise did not develop the condition. Also, seeking specialist legal advice is crucial in order to prove any employer’s negligence to make Industrial Deafness Claims. Founded by brothers Imran Akram and Kamran Akram, Asons Solicitors has developed to become a young and dynamic law firm that delivers practical solutions to clients in times of difficulty.
Its effects could be a temporary ringing in the ears, known as tinnitus, but will lead to permanent damage if prolonged, repeated exposure is sustained. Hearing protector comfort has not received the same amount of attention as noise reduction capability. In summary, the data demonstrated that, with some exceptions, normal hearing listeners' ability to localize the backup alarm in 360-degrees azimuth did not improve when wearing augmented hearing protectors (including dichotic sound transmission earmuffs, flat attenuation earplugs, and level-dependent earplugs) as compared to when wearing conventional passive earmuffs or earplugs of the foam or flanged types. The models informed an iterative research process in which the authors used key informant interviews, focus groups, and early versions of the survey tool to identify critical issues expected to be relevant to the success of the hearing loss prevention training. The group averages for A-weighted attenuation were not statistically significant when compared between the video or the written instruction conditions, regardless of presentation order. HPD fit-testing procedures now allow the individual fit-testing of HPD to assist in appropriate selection of HPD for individual workers, to aid in training workers on proper use of HPDs, and a range of other applications. Earplug fit-testing systems are becoming more commercially available and more feasible for field use. An alternative is the use of field-measurement methods, a number of which have been proposed and are beginning to be implemented. We explored the usage rate of custom-molded musician's earplugs (ER-15) among 15 symphony orchestra musicians with a questionnaire, and measured the attenuation properties of their earplugs with a Real-Ear Attenuation at Threshold (REAT) procedure in a sound field. Their continued focus on their staff has seen them awarded with the Investors in People “Gold Award”; which is reflected in the professional and personable approach they take in working with clients. The present study was conducted to evaluate the comfort level of two different types of insert earplugs as well as the attenuation levels achieved by the earplugs. The instruments recorded the temperature and humidity every 10 s and their results were compared.
Exceptions were that in the 90 dBA pink noise, the flat attenuation earplug yielded significantly better accuracy than the polyurethane foam earplug and both the dichotic and the custom-made diotic electronic sound transmission earmuffs. Commonly held attitudes and beliefs associated with occupational noise exposure and hearing losses, as well as issues associated with the use or non-use of hearing protectors, were identified. A total of 103 apprentice carpenters participated in the Year 1 training, were given a large supply of these HPDs, and instructions on how to get additional free supplies if they ran out during the 1-year interval between initial and follow-up training. The experimenter-trained A-weighted attenuations were significantly greater than the written and video instruction for most of the protectors and groups. Although the age when NIHL begins among farmers is unknown, its prevalence is higher among male adolescents who live and work on farms.
Understanding these technologies, their strengths and weaknesses, and appropriate application of the results of fit-testing may enable employers to make improvements in their hearing loss prevention program performance.
Individual fit-testing is no longer used only for research investigations but is being incorporated in Hearing Conservation Programs (HCP) to improve training, document protection and evaluate the effectiveness of the hearing protector element of an effective HCP. We examine one of those methods, namely the field microphone-in-real-ear (F-MIRE) approach in which a dual-element microphone probe is used to measure noise reduction by quickly sampling the difference in noise levels outside and under an earplug, with appropriate adjustments to predict real-ear attenuation at threshold (REAT). Earplug use was found to be low, and the musicians reported that earplugs hampered listening to their own and their colleagues' playing; earplugs affected either timbre or dynamics, or both. They strive to grow and to develop, and their supportiveness and attention to detail ensures that their clients use them time and again. Attenuation levels were obtained with a commercially available earplug fit-test system, and the comfort ratings were obtained by questionnaire. In addition, skin surface pH was measured at the ear canal entrance before and after the task. However, the flat attenuation earplug showed no benefit over the standard pre-molded earplug, the arc earplug, and the passive earmuff.
The training program was then specifically constructed to positively shape attitudes, beliefs, and behavioral intentions associated with healthy hearing behaviors - especially those associated with appropriate hearing protector use.
Forty-two participants responded to the survey a second time a year later and completed the Year 2 training. For each earplug, the noise reduction statistic for A-weighting (NRS A ) and the associated confidence intervals were calculated for the 80 th and 20 th percentiles of protection. The purpose of this paper is to describe how NIOSH created partnerships to promote hearing conservation for this hard-to-reach population. We report on experiments that validate the ability of one commercially available F-MIRE device to predict the REAT of an earplug fitted identically for two tests.
Additionally, several reasons related to discomfort of use were itemized, but the musicians who consistently used their earplugs did so in spite of problems with use.


The primary research objective was to determine whether hearing protector comfort was related to measured attenuation values.
Confusions of front-rear alarm directions were most significant in the 90 dBA noise condition, wherein two types of triple-flanged earplugs exhibited significantly fewer front-rear confusions than either of the electronic muffs.
The goal was to directly address the key issues and overcome the barriers identified during the formative research phase. Significant test-retest differences were found between the pre-training and the post-training survey scores. Across subject groups for each protector, the differences between NRS A ratings were found to be not statistically significant.
Partnerships included organizations and individuals who were trusted sources of information for the target population, young farmers 14-35 years of age and their families, and those who had linkages in rural communities. The REAT values obtained in sound field were relatively close to the manufacturer's nominal specifications, being 13.7 dB, on average. A linear mixed effects model provided evidence for an inverse relationship between comfort and attenuation. On all measures, the diotic sound transmission earmuff resulted in the poorest localization of any of the protectors due to the fact that its single-microphone design did not enable interaural cues to be heard.
Several comparisons evaluating the order of testing, the type of testing, and statistical tests of the performance across the groups are presented. NIOSH engaged partners through exhibits and train-the-trainer workshops at state or national conventions.
In the frequency range studied (0.125-8 kHz), individual variation in REAT was, however, up to 15 dB across the measured frequencies. Ear canal pH became slightly less acidic, but the change was not statistically significant.
Localization was consistently more degraded in the 90 dBA pink noise as compared with the relatively quiet condition of the 60 dBA pink noise. It was designed to be used with the training as an evaluation tool and thus could indicate changes over time in attitudes, beliefs, and behavioral intentions regarding hearing loss prevention. The results indicated that training was able to bring all apprentice participants up to the same desired level with regard to attitudes, beliefs, and behavioral intentions to use hearing protection properly.
NIOSH workshops included basic information on NIHL as well as information on free or low-lost resources that participants could use in training others at schools and community events. However, the largest portion of the error is due to the user's fitting variability and not the uncertainty of the measurement system. Fluctuation in attenuation might be related to low use of hearing protectors, and REAT measured at fixed center frequencies may be too robust a method to uncover it.
A frequency-augmented backup alarm, which incorporated 400 Hz and 4000 Hz components to exploit the benefits of interaural phase and intensity cues respectively, slightly but significantly improved localization compared with the standard, more narrow-bandwidth backup alarm, and these results have implications for the updating of backup alarm standards.
Finally, the training program was fine tuned with industry participation so that its delivery would integrate seamlessly into the existing health and safety training provided to apprentice carpenters. It was concluded that the health communication models used to develop the educational and training materials for this effort were extremely effective. People with hearing conservation expertise have an important role and many opportunities to improve the knowledge and implementation of hearing conservation among those in agriculture. In phase 2, reported elsewhere in this volume, the training program and the survey were tested through a demonstration project at two sites. Mean attenuation was found to be somewhat closer to the nominal attenuation of the ER-9 and ER-15 earplugs up to about 1 kHz, whereas REAT measurements in sound field revealed more even attenuation at frequencies between 1 and 6 kHz. No significant association was found between earplug attenuation properties and earplug use. The complexity of the electrical connections and equipment in the Omega probe system led to loss of three subject's data. We conclude that the hearing conservationist now has available a portable, convenient, quick, and easy-to-use system that can improve training and motivation of employees, assign hearing protection devices based on noise exposures, and address other management and compliance issues. It was concluded that support and determination to get accustomed to hearing protector use are important factors in hearing conservation. The iButton device was more robust, but provided only 256 gradations of temperature and relative humidity. The present study showed that the buildup of heat and humidity can be modeled using linear equations. The present study demonstrates that relatively inexpensive tools and a low-exertion task can provide important information about the under-earmuff environment, which can inform assumptions about comfort during use.
