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. Sensorineural Hearing Loss is a hearing loss due to impairment or degeneration of the cochlear (inner ear) resulting in an irreversible hearing loss. Bilateral Hearing Loss is a hearing loss, either sensorineural or conductive, in both ears. Unilateral Hearing Loss is a hearing loss, either sensorineural or conductive, in one ear only. 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.

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.

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.

Sensorineural hearing loss can be caused by aging, noise exposure, birth defects, medication and viral or bacterial infections.


This can be caused by impacted cerumen (wax), punctured eardrum, birth defects or otosclerosis. 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.
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.

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).
There is no cure for this type of hearing ,loss; however, most patients with sensorineural hearing loss can be helped with hearing aids. Surgery or medication can be an appropriate therapy for conductive hearing loss in some cases. 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.
