Figure: The outer ear consists of the auricle (unlabelled), the external auditory canal, and the lateral surface of the tympanic membrane (TM). Surprisingly perhaps, hypertension, obesity and diabetes is not associated with an increased risk of hearing loss(Shargorodsky et al 2010). Dance clubs are often very loud and may be the main source of loud noise exposure outside of occupational exposure. Musician's earplugs are available in ER-9, ER-15, and ER-25, according to ones need for noise reduction. Although diabetes per se is not associated with an overall greater risk of hearing loss (Shargorodsky et al 2010), hearing loss starts at an early age than the normal population.
Diabetics are also more prone to get external and middle ear infections, as well as more prone to develop cranial nerve palsies and stroke.
As diabetes is commonly an autoimmune disorder, autoimmune inner ear disease may also contribute.

Also referred to as noise-induced hearing loss, sensorineural hearing loss is caused by damaged or destroyed hair cells in the inner ear that no longer transfer sound information to the brain. Sensorineural hearing loss can rarely be corrected medically or surgically, so hearing aids are the primary solution. Since sensorineural hearing loss is typically caused by exposure to loud noises, we highly recommend the use of ear protection if you find yourself around loud noises frequently. If you have any questions about sensorineural hearing loss or hearing loss in general, please contact one of our locations to speak with an audiologist.
Sensorineural hearing loss may originate from the inner ear, the vestibulocochlear nerve, or the brain.
Sensorineural hearing impairment is hearing loss caused by damage to the structures of the inner ear, the auditory nerve, or the auditory cortex in the brain, which is responsible for interpreting signals from the auditory nerve. Other conditions that can contribute to sensorineural hearing impairment include otosclerosis, a congenital disease characterized by overgrowth of the bone surrounding the structures of the inner ear.
Hearing aids can help relieve the symptoms of sensorineural hearing impairment in many patients. The results of a patient's hearing screening are illustrated on a graph called an audiogram. An audiogram indicates how much hearing varies from normal and, if there is a hearing loss, where the problem might be located in the hearing pathway.
Frequency or pitch of sound is measured along the horizontal axis of the graph in Hertz (Hz), from 125Hz to 8,000Hz. Normal, young, healthy human ears can hear frequencies as low as 20Hz and as high as 20,000Hz.
Loudness or level of sounds is measured along the vertical axis of the audiogram in decibels (dB). The audiogram shows how loud a sound has to be for the patient to hear it at a particular frequency. Air conduction thresholds for the right ear (that is, the softest sounds the right ear can hear at each frequency) are marked as an 'O' and the left as an 'X' on the audiogram. Bone conduction thresholds are marked on the audiogram as (better ear), [(right ear) or] (left ear). In the example above, the patient can't hear high pitched sounds as well as the low pitched sounds. If the hearing thresholds obtained by bone conduction are the same as the air thresholds, this indicates no blockage in the outer or middle ear. A sensorineural hearing loss can be caused by exposure to excessive noise, or by the ageing process.
There is rarely any medical treatment for sensorineural hearing losses and so the impairment is permanent.

If the bone conduction hearing thresholds are normal, but there is a loss of hearing for air conduction sounds, this is called a conductive hearing loss. This means that the cochlea is normal, but there is some blockage to sound in the middle or outer ears. It is possible to have both a sensorineural and a conductive hearing loss - for example, if a person has a noise caused impairment and a perforated ear drum. The degree of hearing loss essentially describes the degree of impact on a person's everyday life.

LACE communication enhancement and rehabilitation is suitable for people with apparently normal hearing abilities, as well as for people who struggle with communication and listening for a variety of reasons. The LACE Auditory Training system is suitable for sensorineural hearing loss treatment, conductive hearing loss and APD solutions to help people manage and cope with a vast array of hearing conditions. Because LACE is aimed at helping users learn to listen and optimise their existing hearing abilities, it can be used to support other care regimes and interventions to create a complete care package that treats each individual according to their own specific needs.
For more information on hearing and addressing a hearing loss or treatments for hearing loss, contact a Registered LACE Training Centre or your local hearing centre. Persons with cochlear deficits fail OAE testing, while persons with 8th nerve deficits fail ABR testing. The middle ear includes the medial surface of the eardrum, the ossicular chain, the eustachian tube, and the tympanic segment of the facial nerve.
Postmeningitic hearing loss can be due to lesions of the cochlea, brainstem and higher auditory pathways, but usually is related to suppurative labyrinthitis (cochlear).
It is a subtype of sensorineural hearing loss, and because it is due to cochlear damage, it is more specifically a cochlear problem. We have encountered several patients in our practice with transient hearing loss after going to a loud club. These ear plugs require a visit to a clinic to get an impression made, so that they are specific for the ear being fitted.

Unsuccessful cochlear implantation in two patients with superficial siderosis of the central nervous system. Hearing loss of this sort is often caused by prolonged exposure to very loud noise, though auditory pathways (or hair cells that transfer sound) in the brain are sometimes abnormal at birth, resulting in some level of hearing loss. Correctly fitted hearing aids amplify tones based on an individual’s unique sound deficiencies.
It's different from conductive hearing impairment, which normally occurs in the middle or outer ear, and is usually the result of a blockage of the ear canal that stops sound waves from reaching the inner ear. Exposure to very loud noise, such as industrial or construction noises, or even loud music, can damage the sensory cells of the cochlea, leading to hearing impairment. The structures of the inner ear can gradually wear out over the years, leading to age-related sensorineural hearing loss.
Often, the hearing impairment associated with ear infections is conductive, and stems from the build-up of fluids in the ear canal.
This bone overgrowth can eventually interfere with the structures responsible for transmitting sound to the auditory nerve, and can lead to total deafness.
Surgery can help some, such as those suffering from otosclerosis, to regain some of their hearing. For example, 250 Hz sounds like middle C on the piano, while the high pitched ringing of the telephone is about 3,000Hz.
However we only test hearing in the range of 250Hz to 8,000Hz, as most sounds of speech occur in this frequency range.

Conversational voice level is around 65dB, and 120dB is very loud - about as loud as a jet taking off if you are standing 100 metres away. You can see this by looking at the sloping line on the graph: as the frequency increases the required sound level also increases before the patient can hear it. Middle ear conditions caused by these blockages can often be corrected by medical or surgical treatment.

Hearing losses are classified as a sensorineural loss or a conductive loss – or a combination (a mixed loss). The inner ear includes the auditory-vestibular nerve, the cochlea and the vestibular system (semicircular canals). The piccolo generates sound levels up to 112db…roughly equivalent to a jackhammer at 30 feet. Pathological studies suggest that it is due to microangiopathic involvement of inner ear blood vessels and subsequent stria vascularis atrophy and hair cell loss (Fukushima et al, 2004).
Typically, sensorineural hearing loss reduces the ability to hear faint sounds or causes speech to sound faint or muffled, which results in the need for sound amplification.
In most cases, total communication is greatly improved through the addition of hearing aids. Sensorineural hearing loss can occur due to aging, infections, tumors, the use of certain drugs, or congenital deformities, among other things.
Noise-related hearing impairment can be prevented by avoiding loud noises, or by wearing ear protection during exposure to loud noises. Ear infections that aren't treated, however, can spread to the inner ear, damaging the structures there. Autoimmune disorders, including lupus and rheumatoid arthritis, can lead to an immune reaction that damages the auditory cells of the cochlea, causing progressive hearing impairment.
For those with severe hearing loss, cochlear implants can help send sound signals to the auditory nerve and the brain's auditory cortex. Further, the accuracy, currency and completeness of the information available on this Web site cannot be guaranteed.
Alternatively, there are a number of conditions, such as Auditory Processing Disorder  (APD) that may appear to be related to hearing-loss. Presbycusis advances so slowly, however, that patients often experience no noticeable impairment in hearing until they reach their senior years. The use of certain prescription drugs, including chemotherapy drugs, can contribute to sensorineural hearing loss by damaging the auditory cells in the cochlea. Lip reading, sign language, closed captioning, and lighted alarm systems for telephones and doorbells can help those with severe hearing impairment cope with their condition. Cirrus Media Pty Ltd, its affiliates and their respective servants and agents do not accept any liability for any injury, loss or damage incurred by use of or reliance on the information made available via or through myDr whether arising from negligence or otherwise. However, APD is neither a senorineural loss or a conductive loss, but is a condition that affects the way an individual processes the sounds that they hear. Patients can usually benefit from one of many treatment options to improve impaired hearing.
Radiation therapy can also damage these cells, and it can damage the auditory cortex in the brain.
