Who are our clients with hearing loss and how can we best facilitate effective communication?
What are the characteristics of hearing loss and what are ways of diagnosing and treating people with hearing loss?
How can vocational rehabilitation professionals appropriately prepare to serve consumers with hearing loss?
Where can people with hearing loss find current information, long-term support and tools for self-advocacy? Sensory loss occurs when there is damage to the cochlea, the end organ of hearing that lies deep within the temporal bone. See healthy stereocilia, from the tops of the outer and inner hair cells through the membrane covering them in photo A. Acoustic trauma refers to damage that occurs to the ear or auditory system from sound waves that are very loud.
Most damage from acoustic trauma occurs in the cochlea; the high pitch areas of the cochlea are more susceptible to damage than the low pitch areas.
If immune components such as immunoglobulin get into the inner ear, that exposure can produce localized immune response and possible hearing loss. Physicians may find it difficult to diagnose autoimmune inner ear disease and often have an extensive protocol of tests to determine the underlying pathology.
The important idea for VR Counselors is that this hearing loss occurs very quickly with no ‘warning’. Meniere’s is said to be caused by endolymphatic hydrops, a condition with too much fluid in the inner ear.
These drugs have different levels of ototoxicity, and other factors such as dosage and duration of taking the drug can have effects.
We now know that a genetic change in the mitochondrial DNA, ‘A1555G’, makes the individual very susceptible to hearing loss given even modest amounts of aminoglycosides.
Typically labeled ‘hearing loss due to aging’, presbycusis has recently been shown to have a definite genetic component. In the past we thought the environment one lived in was the biggest contributor to presbycusis, but we know now that genetics plays a much larger role than we thought.
The hearing loss configuration most often seen in presbycusis is labeled ‘sloping’; the X’s and O’s will be normal or near-normal in the low pitches and will move down the audiogram (worse hearing) in the mid- and high frequencies.
A fairly new type of hearing loss that has recently been shown to have a genetic basis is auditory neuropathy spectrum disorder (ANSD).
People who suffer from auditory neuropathy report that speech understanding, even in quiet environments, is very hard. Other problems that can exist with the eighth nerve or the central nervous system are tumors, the most common one probably being an acoustic neuroma. There are other medical conditions which might impair function of the eighth nerve, most commonly Multiple Sclerosis (MS). Other demyelinating diseases that may have hearing loss involvement include Charcot-Marie-Tooth syndrome, Devic Disease, Guillain-Barre Syndrome, a group titled Leukodystrophies and Progressive Multifocal Leukoencephalopathy.
Tests developed to diagnose APD can generally be used only with people who have normal hearing, which makes APD quite different from all the other hearing loss causes in this module. Treatments for APD are varied and dictated by the specific problems that individuals demonstrate. According to US government statistics from the 60's (National Center for Health Statistics), only 8% of the entire US population has any difficulty with hearing at all. Examples of conditions that cause sensorineural hearing loss are noise and just living a long time. If you have a sensorineural hearing loss, your goal should be to find out why, if you can prevent it from getting worse, and if a hearing aid could help you in overcoming the impairments associated with hearing loss.
If you have to have a hearing loss, it is best to have a conductive one, as these disorders are often fixable.
If you have a conductive hearing loss, your goal should be to find out why, if you can prevent it from getting worse, and if a hearing aid, surgery, or perhaps just wax removal might help you in overcoming the impairments associated with hearing loss.

The Heart of the Matter: What Does America Really Know about Coronary Artery Disease Treatments? The device comes with 4 different musical tracks fully personalized depending on individual’s hearing level and tinnitus. Researchers are learning a lot about cochlear function but there are few medical treatments available at present.
Photos B, C and D show various losses of inner and outer hair cells resulting from some insult to the cochlea. Loss of outer hair cells is thought to be the most common form of cochlear damage and to underlie most cases of sensory hearing loss that range from mild to about moderately severe. In many cases the individual recalls a single incident that, in all likelihood, caused their hearing loss. However, the hearing evaluation can reveal anything from a mild loss to a profound hearing loss. The fluids in the IE are protected by tissues that allow only some of the body’s fluids and molecules to enter.
This hearing loss is caused by autoimmune inner ear disease, usually occurs in both ears, called bilateral loss, and is progressive but at different rates in each ear. If these problems are present they tend to be episodic and between these episodes the person may exhibit ataxia, walking with a very wide gait to keep from falling down.
If medical treatment is somewhat successful or not successful, these individuals will be functionally impaired almost immediately and obtaining audiologic treatment and VR services as quickly as possible will be important to and for them.
The low frequency sensorineural loss in Meniere’s is rare, as most other damage to the cochlea causes high pitched sensorineural hearing loss. This means that symptoms occur, the person experiences hearing loss, dizziness and tinnitus and then those symptoms recede.
However, the audiologist will ask about noise exposure activities and medical history to uncover possible causes for the hearing loss. The two largest categories of ototoxic medications are the aminoglycoside family and some members of the platinum chemotherapy drug family. In addition, some drugs will affect the cochlea more while other drugs may affect the vestibular, or balance system more.
A person’s genetic makeup interacts with the environments in which they grow up and live (for example, noisy or quiet job, exposed to ototoxic medications or not), that determine when, how fast and how much cochlear hearing loss they will suffer. As of 2011, at least two gene mutations have been identified in individuals with presbycusis, with another four genes thought to contribute.
ANSD is characterized by normal functioning of the outer hair cells, and therefore some hearing tests ( otoacoustic emissions), are normal.
It has also been shown that this disorder can result in auditory thresholds that fluctuate over time and for some people thresholds depend on the temperature. Some people respond well to hearing aids, while for others amplifying the signal is painful and not helpful. Less common but equally devastating would be tumors from a genetic condition called neurofibromatosis type II. However, common symptoms of APD include trouble understanding speech in background noise, sound localization and discriminating timing differences and auditory patterns in speech. Testing an individual for APD should include a typical hearing evaluation as well as a special set of tests designed to measure various auditory capabilities. Furthermore, only 3% of the population had difficulty hearing anything other than faint speech. Adults with hearing loss are more likely to be unemployed and earn less wages (Jung and Bhattacharyya, 2012). If we do the math, 90% of 8% of the population with a hearing loss works out to about 7% of the population. Persons with cochlear deficits fail OAE testing, while persons with 8th nerve deficits fail ABR testing.


If we do the math again, as only 8% of the population has a hearing loss at all, and 90% of them are sensorineural, this means that only 0.8% of the population has a conductive hearing loss.
Central hearing loss generally isn't helped to a great extent by medication or surgery, but preventing progression is important. Sudden hearing loss as well as Congenital hearing loss may be due to sensorineural, conductive or central mechanisms. Association of hearing loss with decreased employment and income among adults in the United States .Ann Otol Rhinol Laryngol. Researchers hypothesize that severe to profound sensory hearing loss includes loss of outer and inner hair cells.
If there is outer ear or middle ear damage it is first and foremost a medical problem which the physician will treat before an audiologist offers any treatment. Antibodies, also known as immunoglobulin, are proteins that the immune system uses to identify and get rid of foreign objects like bacteria and viruses. Whenever the amount of hearing loss is different in each ear it is called asymmetric hearing loss. Another symptom commonly reported is roaring tinnitus, something like the roar in the seashell. The individual may have no problems for weeks, months or even years, until another episode occurs.
Often, transient sounds or more on the order of milliseconds or tens of milliseconds (that is, thousandths of a second). Tinnitus, or ringing in the ears, may be the presenting complaint as well as difficulty understanding speech in a noisy background, which is perhaps the most common complaint of everyone who has cochlear hearing loss. At first, frequencies above 4,000 Hz have the better thresholds but as a person ages, these thresholds may become poorer as well.
If an individual is in need of any of these drugs hearing loss is often a secondary consideration because their life may be at risk. Audiologic treatment should begin as quickly as possible, and services from vocational rehabilitation will be critical for these individuals to continue to function well day to day. In addition, diet, stress and other systemic conditions such as diabetes, may also add to hearing loss in the ‘presbycusis’ category. With ANSD, the signal becomes ‘corrupted’ when it reaches the inner hair cells and must cross the synapse to the acoustic (eighth) cranial nerve. A third treatment type lies in making changes to the person’s environment to facilitate their listening capabilities, such as with an amplified telephone or an assistive device called a frequency modulated or FM system. In US data between 1988 and 2006, mild or worse unilateral hearing loss (25 db or worse), is reported in 1.8% of adolescents.
If you are older, statistics say that while many of your older associates may have the same problem, it will probably get worse, so you should prepare yourself and do your best to slow down the rate that it gets worse. Many conditions that occur within the cochlea result in the loss of outer or inner hair cells.
Hearing levels may recover to some extent, but few people regain absolutely normal hearing.
Physicians may suggest reducing caffeine and salt, which many people say helps to some extent. In other cases, the person may benefit from the use of an oral interpreter who silently mouths the words so the person with ANSD can use speech-reading to understand.
In that case, amplification on that ear would not be helpful; however, that individual may find the need for a hearing aid set up to pick up environmental sounds on the affected side and send them to the other ear.
There was greater risk in individuals with work exposure to loud noises, lower socioeconomic background and in ethnic minorities. Other things that cause conductive hearing losses are fluid in the middle ear, and disorders of the small bones (ossicles) in the middle ear.
Photograph A) below shows healthy stereocilia, projection from the tops of the outer and inner hair cells through the membrane covering them. There are also several surgical procedures that might be used in cases of intractable vertigo. Researchers have discovered that workers exposed to noise and some chemical substances (such as toluene and xylene) simultaneously can suffer greater amounts of hearing loss and cochlear damage than if they are exposed noise alone.
