The Industrial Injuries Disablement Benefit scheme (IIDB) had 130 new claims in 2014, compared to 120 and 125 in 2013 and 2012 respectively. Vowel sounds like a short a€?oa€? as in the word a€?hot,a€? have low frequencies (250 to 1,000 Hz) and are usually easier to hear. Consonants like a€?s,a€? a€?h,a€? and a€?f,a€? have higher frequencies (1,500 to 6,000 Hz) and are harder to hear.
Sounds that are 120 dB or louder can be painful and can result in temporary or permanent hearing loss.
Different groups and organizations use decibels to define the degree of hearing loss differently. The following discussion, written by Steve Barber, provides a look at the people that make up the broad category we call “Deaf and Hard of Hearing”. Hearing loss or deafness can affect people of any age, but the incidence rises, as we grow older.
People who are deaf (often written with a lower case “d”) also have little or no hearing, but they typically do not use American Sign Language as a primary language and often have no signing ability at all. Although most people who experience hearing loss do not become deaf, many people do become completely deaf later in life due to gradual or sudden hearing loss. People with a profound hearing loss usually must use assistive technology in addition to powerful and full-featured hearing aids in order to understand speech.
People with a severe hearing loss usually can use hearing aids and assistive technology to communicate effectively in most situations.
People with a moderate hearing loss can communicate in many situations even without hearing aids. Prevalence of fair or poor health status, difficulties with physical functioning, and serious psychological distress increased with degree of hearing loss (Table 2 and Figure 3). In this report, disparities in selected health status characteristics and health risk behaviors were found by hearing status: adults with hearing loss had poorer health and increased risk of engaging in health risk behaviors than adults with good hearing.
Barriers to optimal medical care for adults with hearing loss have been identified by the medical community and specific suggestions for effectively addressing the needs of these patients have been offered (5-8). The National Health Interview Survey (NHIS), a survey of the noninstitutionalized civilian population of the United States, has been an important source of information about health and health care in the United States since it was first conducted in 1957. Data collected in the 2000-2006 NHIS core questionnaires were combined to increase the reliability of the estimates.
1 Hearing status is based on the question, "Which statement best describes your hearing without a hearing aid: Good, a little trouble, a lot of trouble, deaf? 3 In a series of separate questions, respondents were asked the degree of difficulty they experienced performing nine physical activities by themselves, and without using any special equipment.
People with hearing aids are almost two times more likely to be employed than their peers with hearing loss that do not regularly use hearing aids. There are many physical and mental health conditions that are associated with the loss of hearing in retirees.
While the majority of hearing loss is genetic, it is important to remember to minimize the negative impacts of your environment. The graphic points out that the four main ways people lose their ears are through listening to loud music, spending too much time in an industrial work place with power drills and the like, being exposed to the sounds of a racetrack, and being exposed to the sounds of guns firing for long periods of time. A person who has hearing within the normal range can hear sounds that have frequencies between 20 and 20,000 Hz. A person with hearing loss may refer to themselves as Deaf, deaf, hard of hearing, hearing impaired or just refuse to associate themselves with any of these terms. The word “Deaf”, (often written with a capital “D”) typically refers to people who use American Sign Language as a primary language – either directly with others who sign or indirectly through an interpreter with people who do not sign. These late-deafened people often choose not to learn sign language, or to identify with the “Deaf Culture”. Even the best hearing aids and assistive technology will not restore enough hearing to understand speech for people with profound hearing loss in less than optimal situations. This technology does not provide “normal” hearing for them, but can usually provide sufficient improvement that understanding speech is possible in all but the worst of situations.
Even with hearing aids, people with a moderate loss will have difficulty in noisy environments or when they can’t see the person they are speaking with.


Adults who were deaf or had a lot of trouble hearing were about three times as likely as adults with good hearing to be in fair or poor health and to have difficulty with physical functioning (such as walking, bending, reaching, etc). Analysis of differences by age (not shown) revealed that disparities in health risk behavior prevalence between adults with and without hearing loss are largely concentrated among adults under age 65.
The reasons for higher rates of smoking, alcohol use, leisure-time physical inactivity, obesity, and inadequate sleep among adults with hearing loss compared with adults with good hearing cannot be determined from this analysis. Increased attention to the unique health care and health information needs of adults with hearing loss may help reduce disparities identified in this report. NHIS is a multistage probability sample survey that is conducted continuously throughout the year by interviewers of the U.
Communicating about health care: observations from persons who are deaf or hard of hearing. Other races and multiple races not shown due to unreliability associated with small sample sizes for this analysis.
While the effects may not be noticeable at the start, soon the clamor of life will catch up to us all. In the United States, at least 1.8 million children have hearing problems, and over 6 million are between the ages of 18 and 44. Because of high risk professions, 26 million Americans between the ages of 20 and 69 have high frequency hearing loss. Nearly half of adults over the age of 75 have some form of hearing loss, and this can lead to more hospitalizations associated with dementia, diabetes, and cardiovascular disease if their hearing loss remains untreated. Someone who cannot hear high-frequency sounds will have a hard time understanding speech and language. They may hear environmental sounds, and may even understand some speech, but they identify with what is known as the “Deaf Culture”. Most people are aware that their hearing loss is a significant limitation for them and will do anything needed to over come it. Some people with severe hearing loss may still be in denial and refuse to use hearing aids or assistive technology, but a large percentage of those with severe hearing loss do use hearing aids effectively and many also supplement that with assistive technology. Certainly, hearing aids could make a huge difference for them in making speech clearer, and many more people are using this technology, now that hearing aids are better able to fit their needs. These adults were more than four times as likely as adults with good hearing to have experienced serious psychological distress. Media and other public health campaigns that use auditory techniques to promote healthy behaviors among the U.S. Computed using the imputed income files released by the National Center for Health Statistics. Estimates are based on household interviews of a sample of the civilian noninstitutionalized population.
It is estimated that by 2015, the total number of people who suffer from hearing loss of over 25dB will be more than 700 million. Of these suffering some degree of hearing loss, 90 percent can be helped by the use of a hearing aid.
While most hearing aids mimic the same electronic components, there are multiple style varieties, as well as the conversion of sound using analog or digital technology.
Many were raised by hearing parents, who wanted their children to remain part of the “hearing world”. Some people with profound hearing loss may continue to deny that it is a serious problem and may withdraw from society or situations where hearing is required. While some people with a moderate hearing loss do not use hearing aids because of the cost, denial or unwillingness to admit that they have a hearing loss is more often the reason.
The National Healthy People Objectives for 2010 include goals to reduce prevalence of hearing loss as well as goals to eliminate health disparities among persons with disabilities (4).
Adults who had a little trouble hearing also had higher rates of these health problems compared with adults who considered their hearing to be good.
Among adults aged 18-44 years, more than 40% of those who were deaf or had a lot of trouble hearing currently smoked cigarettes compared with 24% of those with good hearing. Census Bureau for the Centers for Disease Control and Prevention's National Center for Health Statistics.


Denominator for each percent distribution excludes persons with unknown selected health characteristic. Denominator for each percent distribution excludes persons with unknown selected health behavior characteristic. In the United States alone, hearing loss is projected to affect 40 million people by 2025, and by 2050 reach almost 53 million.
As nine out of ten children who are born deaf are born to parents who can hear, it is important to understand the risks we take every day that can damage our hearing. This can cause a major problem in the workplace, and approximately $30,000 is lost in income by workers with untreated hearing loss.
We have 15,000 hair cells, but they can deteriorate rapidly if people consistently place themselves in situations where hazardous noise is present. Most people with a moderate hearing loss can substantially benefit from hearing aids and would not normally use assistive technology beyond an amplified phone to supplement hearing aid use.
Accommodations are needed for adults who do not hear well to ensure equal access to health services (5,6). These age-related increases in deafness or a lot of trouble hearing were similar for men and women (Figure 1).
Diabetes and high blood pressure were more prevalent among adults who were deaf or had a lot of trouble hearing, compared with adults with good hearing.
Disparities in smoking prevalence persisted among middle aged adults but were not found for adults aged 65 years and over, an age group for which hearing loss is more prevalent and smoking rates are generally low.
Inclusion of communication modalities appropriate for adults with hearing loss may aid in reducing health risk behaviors in this population. Young children who suffer from length ear infections of three or more months, extreme volume exposure in music, or secondhand smoke can all increase the risk of hearing loss for children and teenagers.
These people can easily become underemployed, but this issue can be resolved with the use of hearing aids. Over 50 million Americans suffer from a disease called Tinnitus, which is a non-stop ringing in the ears that results from prolonged exposure to loud sounds.The right bar of the graphic discusses how to protect your ears. Services mandated by the Americans with Disabilities Act have improved access for this group of Americans, but disparities in access to health care and health information remain (7-9).
Analysis of differences by age (not shown) indicated that these disparities were greatest among adults under age 65. Questions about hearing status, developed in collaboration with researchers at Gallaudet University, were first asked in the NHIS in 1962-1963 (10). Point estimates and estimates of their variances were calculated using the SUDAAN software package (21) to account for the complex sample design of the NHIS. The goal of this report is to highlight disparities in health status and health risk behaviors of interest to the health community working to meet the needs of adults with hearing loss. Subsequently, hearing questions were asked in supplement questionnaires in 1970, 1971, 1977, 1990, and 1991 (11-15). However, most people who identify themselves as “Deaf” are “Born Deaf” or at least became Deaf pre-lingually (before acquiring spoken language).
Adults with the most education (a bachelor's degree or higher) and those with the highest incomes were somewhat less likely than other adults to have any trouble hearing, although the differences were not large. Since 1997, questions about hearing status have been asked annually in the NHIS Sample Adult Core questionnaire. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level. Lack of comments regarding the difference between any two estimates does not necessarily mean that the difference was tested and found to be not significant.
All estimates shown meet the NCHS standard of having less than or equal to 30% relative standard error.
