Hearing loss is an epidemic in the United States, affecting one out of every five people in the country.
MARYLAND: Montgomery County, Bethesda, Rockville, Gaithersburg, Germantown, Olney, Kensington, Potomac, Chevy Chase, and Silver Spring. In principal the function of peripheral hearing is to convert sounds (air pressure differences) into electrical signals..

Easy-to-read, question-and-answer fact sheets covering a wide range of workplace health and safety topics, from hazards to diseases to ergonomics to workplace promotion.
The data in the table below show how audiometric readings are converted into percent hearing impairment. From the scientific data accumulated to date, it is possible to determine the risk of hearing loss among a group of noise exposed persons.
Some of the most troublesome signs of getting older are hearing loss, depression and declining cognitive skills. A significant number of older adults and senior citizens have hearing loss, but have yet to have it treated. The study found that those living with unaddressed hearing problems were more susceptible to anxiety, depression and paranoia. Aside from being more likely to exhibit downbeat emotions, the NCOA report found that untreated hearing loss may cause older adults to hold irrational views about other people. The NCOA isn’t the only group to trace seemingly unrelated medical issues to diminishing hearing.
Among those with symptoms, 52% had increased irritability and frustration, 22% struggled with sleep or restlessness and 18% lost interest in activities they usually enjoyed.
Evidence has recently emerged that indicates hearing loss may also affect the brain’s cognitive skills, or its ability to think, reason, store and recall information and solve problems. After collecting and analyzing their data, the research team found that the seniors with hearing loss suffered a quicker erosion of their cognitive skills than those with normal hearing.
The authors of the report cautioned that their efforts did not definitively prove a connection between hearing loss and cognitive impairment. Hearing loss touches the lives of millions of Americans, yet many older adults and seniors do not get proper treatment for this ailment. It is highly advisable for older adults to consult with their doctor regarding possible hearing loss. The device comes with 4 different musical tracks fully personalized depending on individual’s hearing level and tinnitus.
The 0 dB threshold shift reading of the audiometer represents the average hearing threshold level of an average young adult with disease-free ears. To do this we need the following data: A measure of daily noise exposure level Duration of noise exposure (months, years) Age of person Figure 1Figure 1.


The effect of expending extra effort comprehending words means there are fewer cognitive resources for higher level comprehension. Unfortunately, these are not uncommon problems; roughly 36 million Americans suffer from hearing loss to at least a certain degree. The National Council on the Aging (NCOA) took a hard look at this issue, conducting a study on how untreated hearing loss impacted the mental wellbeing of adults over the age of 50.
Furthermore, the subjects in this group acted more withdrawn, showing less inclination to partake in social events. The researchers asked their subjects if they agreed with the statement that “other people get angry at me for no reason,” a tactic commonly used by psychologists when examining patients for paranoia. Australia’s Department of Human Services (DHS) produced its own study on the issue in 2008, and reached a similar set of conclusions.
A JohnsHopkinsUniversity study found that hearing loss is often followed by a steady decline in cognitive health.
Based on participant’s test scores, the Johns Hopkins study estimated that an older adult with hearing loss would develop cognitive impairment in slightly under eight years.
According to the AmericanAcademy of Audiology, roughly sixty percent of older Americans with hearing loss do not use hearing aids. Along with improving a patient’s hearing capabilities, hearing aids might provide an indirect emotional boost as well.
Hearing aids not only help to regain lost hearing abilities, but may also have a positive effect on the patient’s demeanor and temperament. Non-auditory effects include stress, related physiological and behavioural effects, and safety concerns.
Certain medications and diseases may also cause damage to the inner ear resulting in hearing loss as well. The PTS (permanent threshold shift), as measured by audiometry, is dB level of sounds of different frequencies that are just barely audible to that individual. Percent of exposed population with hearing loss greater than 25 dB for various noise levels and years of exposure as given by the ISO 1999-1990 method. Likewise, nearly one in ten adults in the United States must contend with depression, and millions of seniors suffer from poor cognitive health. Upon surveying 2300 participants, the NCOA team concluded that failing to properly address hearing loss could have major consequences for older patients. When asked about experiencing recent periods of prolonged sadness or depression, adults with severe hearing loss were more likely to answer in the affirmative if they did not wear hearing aids (30 percent of adults fitting this criteria responded “yes,” as opposed to 22 percent for hearing aid users). The subjects who were not using hearing aids were far more prone to answer “yes” to this question (23 percent) than those using them at the time of study (14 percent). Publishing their work in the January 21st, 2013 issue of the Journal of the American Medical Association (JAMA), the Johns Hopkins team observed nearly 2,000 volunteers over the age of 70.
This was significantly shorter than the eleven-year estimate for adults with normal hearing capabilities. The reasons for this figure vary; some people may not be able to afford hearing aids, while others feel that they simply don’t need them.


The NCOA study observed that older adults who began wearing hearing aids reported major improvements in many areas of their personal and social lives.
Generally, it is not possible to distinguish sensory-neural hearing loss caused by exposure to noise from sensory-neural hearing loss due to other causes. A positive threshold shift represents hearing loss and a negative threshold shift means better than average hearing when compared with the standard. The average hearing threshold level at 500, 1000, 2000, and 3000 Hz should be calculated for each ear. As bad as these conditions are, at least there is no connection between them – or is there? To better ensure the accuracy of the report’s findings, medical professionals administered standardized hearing tests to each participant. Noise-induced permanent hearing loss is the main concern related to occupational noise exposure. Hearing ability may continue to worsen even after a person stops work in a noisy environment.
Given a noise-exposed person, it is not possible to determine whether or not his or her hearing loss is due to noise.
According to recent studies, adults with deteriorating hearing may also see problems with other aspects of their health. Additionally, the researchers employed the same set of brain and hearing tests throughout the duration of the study. However, in a group of exposed persons, the percentage of population with hearing loss depends on the level of noise exposure and the duration of exposure. Multiplying should calculate the percentage of impairment for each ear (the monaural loss) by 1.5 times the amount by which the above average exceeds 25 dB (low fence).
For higher noise exposure levels, and longer durations of exposures, a larger percentage of exposed persons acquire hearing loss. This observation forms the basis for calculating noise-induced hearing loss as outlined in the international standard ISO1999-1990 and American National Standard ANSI S3.44 - 1996. The hearing impairment is noticeable only when it is substantial enough to interfere with routine activities.
The hearing disability (binaural assessment) is calculated by multiplying the smaller percentage (better ear) by 5, adding it to the larger percentage (poorer ear), and dividing the total by 6. Noise-induced hearing damage cannot be cured by medical treatment and worsens as noise exposure continues.
