Sixteen percent of adults suffer from hearing loss great enough to adversely affect their daily life.
We all lose some of our hearing as we age, but some lose more of their hearing than others. A hearing loss occurs when the ear’s ability to conduct sound from the outer ear, through the middle ear into the inner ear and further into the brain is damaged or reduced.

Sensory presbycusis: This refers to epithelial atrophy with loss of sensory hair cells and supporting cells in the organ of Corti.
Mechanical (ie, cochlear conductive) presbycusis: This condition results from thickening and secondary stiffening of the basilar membrane of the cochlea. The rest of my answer is based on this book, some parts of which exist online (which I'll quote). As you can see from the graph, severity of age-related hearing loss depends on sound frequency: older people need high-pitched sounds to be displayed more loudly, in order to hear them. It's not described much on the website, but the book explains that there is a relationship between how loud a sound has to be to harm you, and which frequency it is. Here's a plot of the connection between loudness and frequency in auditory perception, in which you can see that sounds around 4kHz can most easily harm us.

Early detection of hearing loss and immediate intervention for people with intellectual disabilities (ID) are imperatives for their cognitive, social, and vocational well-being.
The following brief review highlights the literature reports of hearing findings for children with DS and adults with ID residing in institutional settings. Other studies have discussed the hearing status of adults with ID residing in institutional settings, reporting rates of hearing loss ranging from 21% to 70%. With the above as background information, let's now review the recently reported study of hearing outcome findings of 9,961 non-institutionalized individuals with ID (Herer, 2012).
The hearing examination protocol for this study included ear canal examinations, otoacoustic emissions (OAE) screening, pure tone screening at 25 dB for 2,000 Hz and 4,000 Hz using air-conduction earphones, and tympanometry screening. The outcome results for the 9,961 individuals with ID were gathered at seven Special Olympics (SO) sports events from 2004 through 2011.
Further, Table 1 reveals that the overall prevalence rate of sensorineural hearing loss (SNHL) for people with ID across the seven SO events was 12.8%, a rate greater than expected in the general population 18–55 years of age.
Finally, information about ear canal health problems of adults with ID needs to be highlighted in this essay. The prevalence of hearing loss for adults with ID is much higher than for persons in the general population. Hearing loss occurs much earlier in age for adults with ID than those in the general population.
The high prevalence of ear wax in the entire study population with ID emphasizes the need for ear canal examinations on a regular basis for all persons with ID. The present study could not differentiate results for adults with DS from those with ID not a result of DS. The data reported in Table 1 for international events in years 2005, 2007, 2009, and 2011 were not examined by country of origin for the participants at these events. The degree of ID for the adults in the 2012 report was not determined; although it was hypothesized as being mostly mild, based on observation of their social behavior at the sports events in which they participated. Data were not available for the present study participants concerning the following characteristics: gender, race, ethnicity, noise exposure, smoking experiences, cardiac status, diabetes, or medication usage. The ASHA Action Center welcomes questions and requests for information from members and non-members.
Hearing thresholds of an individual may be assessed by both objective and subjective methods. Objective methodsAuditory potentials reflect the electrical activity of the various neural pathways involved in the coding of sounds. Unit action potentials (experimental technique not used in humans)A micro-electrode (black arrow) records electrical activity from a single neurone in the auditory nerve.
Surface electrodes placed on the skull allow recording of 5 main waves of electrical activity through the brainstem. Oto-acoustic emissions (OAEs)They reflect the activity of outer hair cells, which are the most sensitive cells of the organ of Corti.OAEs are very useful for screening newborns, but are also widely used as as an objective test in subjects of any age. The implications differ from person to person, but most people with hearing impairment suffer some social, psychological and physical problems as a result of their hearing loss. Another common reason for hearing loss is exposure to noise, but it can also occur as a result of disease, infections or drugs. The most common categories of hearing loss classifications are mild, moderate, severe and profound hearing loss. If the ear’s ability to conduct sound into the inner ear is blocked or reduced, it is a conductive hearing loss. Hearing loss in smaller children is normally caused by genetic factors, physical abnormalities in the ear or it might be caused by certain diseases.


Characteristically, presbycusis involves bilateral high-frequency hearing loss associated with difficulty in speech discrimination and central auditory processing of information. This process originates in the basal turn of the cochlea and slowly progresses toward the apex. The thickening is more severe in the basal turn of the cochlea where the basilar membrane is narrow. The question is being unable to hear ranges as we get older, starting from childhood, while presbycusis is specific to post middle-aged people. Sounds that are near our auditory thresholds (under 20 Hz and above 20.000 Hz in the normal, healthy hearing range) can't harm us even if they are extremely loud.
The professional literature reports increased prevalence of hearing loss for people with ID compared to their general-population peers. This review provides a framework for understanding the hearing status of adults with ID living in general-community environments as reported in this essay.
These rates varied with age, with individuals younger than age 40 showing lower rates compared with older persons with ID; and those without DS exhibiting lower rates compared with those with DS. One noteworthy and comprehensive investigation (Meuwese-Jongejeugd et al., 2006) in The Netherlands of 1,598 individuals ages 18–70 found an overall prevalence rate for hearing loss of 36%. These adults, 18–55 years of age, participated in sports competition events globally over the past decade sponsored by Special Olympics International.
As seen in Table 1, there were strong similarities and some differences for outcomes among these events. The degrees of loss are much the same for the bilateral and unilateral ear conditions as well.
The results of Figures 1 and 2 illustrate the trend for increased prevalence of hearing loss with each advancing age decade. As shown in Table 1, a high prevalence rate (averaging 41%) of substantial ear wax was identified for the entire 9,961 individuals studied, not just those with hearing loss. Therefore, the hearing loss rates reported in this study may be influenced by the proportion of adults with DS among the total group tested.
The health conditions and care in some countries could influence the rate of hearing loss of their adult citizens with ID. Further study of the hearing of adults with documented degrees of ID and living in their general communities might reveal differences of degree and type of hearing loss by degree of ID and thus influence care planning.
Herer, an audiologist, is director emeritus of Children's Hearing and Speech Center, Children's National Medical Center, and professor emeritus of Pediatrics, George Washington University, Washington, DC. Objective methods are based on recordings of the electrical activity at various stages along the auditory pathway, from the cochlea to the cortex, and do not need the active participation of the individual. This auditory fibre responds to sound stimulation (red dot) by sending an action potential (AP) towards the brain.
The amplitude of the CAP measured between N1-P1 is in the order of several dozen microvolts (µV). It may be inherited or be a result of physical damage to the ears or serious injuries to the head.
In larger children and especially teenagers the hearing loss may often be a result of noise exposure. Some are treated with different types of implants and surgery may cure some types of conductive hearing loss. These changes correlate with a precipitous drop in the high-frequency thresholds, which begins after middle age.
This correlates with a gradually sloping high-frequency sensorineural hearing loss that is slowly progressive.
The wiki page does refer to the issue as presbycusis, yet every reliable source on presbycusis lists it as being limited to post middle-aged people.
We don't hear them because they cause no mechanical change in our ear that responds to those frequencies, and consequently no harm is done. It also reflects undetected hearing loss for individuals with ID, along with undertreated and unserved experiences once hearing loss is identified.
Further, a number of studies indicated a persistent lack of hearing loss identification for many adults with ID prior to their being study subjects. Those study subjects with DS showed significantly greater rates at each age decade compared with the rates for persons with ID unrelated to DS. The hearing status and ear canal health of this very large sample provides informative perspectives of hearing and ear care needs of individuals with ID living within their general communities. All audiometers were calibrated to the appropriate American National Standards Institute standards for pure tone testing. This finding underscores the need for improved ear canal hygiene through regular ear examinations for all individuals with ID.
Another large sample study of adults with ID living in the general community that does differentiate results for adults with DS from those for adults with ID without DS could provide clarification of any differences. Further studies of people with ID living in the general communities of a variety of counties could be helpful in identifying specific care needs in respective countries. For example, one study in the literature (Agrawal, Platz, & Niparko, 2008) noted that hearing loss prevalence increased for those in the general population with smoking and noise exposure experiences, as well as cardiovascular risks. The prevalence of ear, nose and throat disorders in preschool children with Down's syndrome in Glasgow. Obstacles in large-scale epidemiological assessment of sensory impairments in a Dutch population with intellectual disabilities.

On the other hand, subjective methods need the co-operation of the individual being tested, because they rely on the subject's perception of and response to sound. After these early evoked potentials, the same skull electrodes can record later potentials from activity in the thalamocortex (middle latency and cortical auditory evoked responses).
A type of sensorineural hearing loss is called a age-related hearing loss also known as Presbyacusis.
You should also be aware that certain medications and lifestyles may increase the risk of hearing loss. Almost everybody experiences temporary tinnitus, but many have permanent tinnitus which some find very annoying. The abrupt downward slope of the audiogram begins above the speech frequencies; therefore, speech discrimination is often preserved. It seems the wiki page is the only source referring to range of audible frequencies in young people as presbycusis? In the case of age-related hearing loss, the hair cells in the inner ear that should respond to high-frequency sounds, have already stopped responding, so there is nothing left to harm.
The hearing health of children with Down syndrome (DS) has received considerable attention in published reports, and some studies have examined the hearing status of adults with ID in institutional settings. Essentially all investigations recommended regular hearing and health screenings for adults with ID (H. Further, a remarkable 48% of subjects with ID had not been identified with hearing loss before this study was undertaken. The rates of hearing loss for participants with DS ranged progressively from 36.4% (ages 18–30) to 100% (ages 61–70).
All threshold testing was conducted in very quiet sound environments, mostly within sound booths brought to event sites.
These differences may be due to different groups of individuals with ID participating at each event.
This information certainly has implications for the variety of hearing aids that would be useful for these adults. A comparison with general non-ID population data for these age decades (Great Britain-1989 and Italy-1996) is presented in Table 4 and reveals remarkable differences. Further study of adults with ID with these characteristics could be very revealing and possibly lead to preventive or intervention measures for vulnerable groups within the adult population with ID.
The prevalence of hearing impairment and reported hearing disability among adults in Great Britain.
Prevalence of visual and hearing impairment in a Dutch institutionalized population with intellectual disability. Recording acoustic otoemissions is also an objective method, which specifically allows to check outer hair cells motile properties. If there are problems with conducting sound to the inner ear and the hair cells in the inner ear are damaged at the same time, it is called a mixed hearing loss.
A connection between tinnitus and hearing loss has been proven and many people with tinnitus often also have a hearing loss.
Histologically, the atrophy may be limited to only the first few millimeters of the basal end of the cochlea. All testing was conducted by experienced audiologists, speech-language pathologists, and other health care professionals who were trained to use the investigation's protocol. Most important, though, these results reflect the significant unmet need for amplification of these individuals given that most had no prior experiences with hearing aids.
This essay will discuss the hearing status reported for 9,961 non-institutionalized adults with ID (Herer, 2012). These data are in concert with the findings of the previously cited study by Meuwese-Jongejeugd et al. Special Olympics Healthy Hearing Program: Guidelines for standardized screening procedures, 2nd ed. One theory proposes that these changes are due to the accumulation of lipofuscin pigment granules. Herer received his bachelor and master of science degrees in communication sciences and disorders from Syracuse University under the mentorship of Dr. Down syndrome in a population of elderly mentally retarded patients: genetic-diagnostic survey and implications for medical care. He completed his PhD degree in audiology at Northwestern University under the mentorship of Dr. Herer's current interests include the delivery of audiology services in a public health model and audiology graduate education of speech-language pathology students.
There are numerous cases of hearing loss in children - hearing loss affects all age groups.
Since most people with hearing impairments hear well in a quiet environment like a doctor's office, it can be virtually impossible for your physician to recognize the extent of your problem. Without special training, and an understanding of the nature of hearing loss, it may be difficult for your doctor to even realize that you have a hearing problem.
