Some researchers predict that more than two-thirds of U.S. adults aged 70 years or older will have “clinically meaningful” hearing loss by 2060.


That’s according to a study published In the March 2, 2017, edition of JAMA Otolaryngology-Head & Neck Surgery. Researchers looked at national population projection estimates using current prevalence estimates of hearing loss to forecast the growing number of hearing loss cases. According to the study’s authors, adults aged 20 or older with hearing loss will increase from 44.11 million in 2020 to 73.50 million in 2060, with the greatest increase occurring in older adults.

A new survey from the CDC found that one in four U.S. adults who believe their hearing is good or excellent may have hearing damage. Much of this damage, according to the study, results from loud sounds that occur every day at home.

The study found that 20 percent of people who reported no job-related noise exposure had hearing damage in a pattern caused by noise. This damage appeared as early as the age of 20.

The association has submitted a letter of support for legislation H.R. 3384.

The American Industrial Hygiene Association has submitted a letter of support for H.R. 3384, the "Quiet Communities Act of 2015." This legislation would reestablish and reauthorize funding for EPA's Office of Noise Abatement and Control.
According to AIHA's news release, the letter focuses on a 2014 study that estimated more than 104 million individuals in the United States had annual noise exposures at a level that increased their risk of noise-induced hearing loss and other noise-related health effects, such as cardiovascular disease, sleep disturbance, stress, general annoyance, and impaired learning and concentration.

AIHA says that the new legislation will also provide support for two other objectives of the 1972 Noise Control Act, including establishing a means for effective coordination of federal research and activities in noise control and providing information to the public regarding the noise emission and reduction characteristics of consumer products.

Noise, or undesirable sound, is one of the most common health problems in many workplaces. Practically all companies involved in manufacturing, construction, or mining create noise. And because noise is inherent in many work processes, it cannot be totally removed. However, its adverse effects on health can be limited by knowing where to implement engineering controls, administrative controls and the use of proper personal protective equipment.

Perhaps the most widely known detrimental effect of noise is hearing loss, which can be either temporary or permanent. The extent of the damage depends primarily upon the intensity and duration of exposure. In addition to hearing loss, excessive noise levels can also lead to hazardous situations at work, such as an inability to hear warnings, a decrease in the ability to communicate with other employees, and impaired concentration.

In the early 1980s, OSHA established a hearing conservation amendment (29 CFR 1910.95, Occupational Noise Exposure Standard) that requires hearing conservation programs for all employees exposed to noise on an eight-hour, time weighted average (TWA) in excess of 85 decibels measured on an A-weighted scale (85 dBA). The permissible exposure limit is 90 dBA for an eight-hour TWA. (Something to keep in mind is that some states also have regulations that are at least as stringent as OSHA’s.)

Determining whether or not to use engineering controls, administrative controls, or personal protection devices or some combination to meet those requirements involves recognizing that a noise problem may exist, followed by identifying its source or sources and evaluating the extent of the problem. In some cases, identifying both the problem and its source can be obvious, such as when it is apparent that employees aren’t able to talk with one another at a reasonable distance near certain machinery. In many other cases, however, the source can’t be traced so easily, such as in places where multiple machines are in use.

Workplace Safety & Health Co., Inc. can help identify sources of noise in a work environment by conducting a noise survey, which normally includes personal noise exposure sampling using dosimeters and developing a noise contour map, clearly identifying noisy areas. The results can be used to locate specific noise sources, identify which employees should be included in a hearing conservation program, and then determine what form or forms of noise control are best suited to the situation. It all makes for a hearing conservation program that is both compliant and efficient.
