Particular causes of hearing loss will be show up in the clinical audiogram in characteristic ways.
Conductive hearing loss comes about when the transmission of sound to the inner ear is impaired, perhaps due to impacted ear wax (cerum), an ear infection (otitis media with effusion or OME), or calcification of the middle ear ossicles (otosclerosis). It is often possible to treat conductive hearing loss by removing the cause of the physical obstruction. By far the most common cause of sensory neural hearing loss is damage to sensory hair cells in the cochlea. Because our outer and middle ear transmits frequencies near 4 kHz very efficiently, hair cells that are tuned to frequencies near 4 kHz are particularly vulnerable to noise damage. Even if we avoid exposure to very loud noise, the ear's outer hair cells may also simply wear out as we age, leading to age related hearing loss. 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. This web site is intended for Australian residents and is not a substitute for independent professional advice.
Bone conduction implants use the natural capabilities of bone to transmit sound directly to the inner ear.

RehabilitationCochlear implant users of all ages can practice speaking and listening skills with interactive and downloadable (re)habilitation activities.
Any problem in the outer or middle ear that prevents sound from being conducted properly is known as a conductive hearing loss. Sensorineural hearing loss results from missing or damaged sensory cells (hair cells) in the cochlea and is usually permanent.


Mild to severe sensorineural hearing loss can often be helped with hearing aids or a middle ear implant.
Some individuals have a sensorineural hearing loss only in the high frequencies, also referred to as partial deafness. A problem that results from the absence of or damage to the auditory nerve can cause a neural hearing loss.
Hearing aids and cochlear implants cannot help because the nerve is not able to pass on sound information to the brain.
Audiogram: An audiogram is a graph which audiologist use to record results using symbols to depict the threshold for each ear as a function of frequency and intensity. Normal young, healthy human ears can actually hear frequencies as low as 20Hz and as high as 20,000Hz.
Bone conduction thresholds are marked on the audiogram as P (better ear), [(right ear) or] (left ear). If the hearing thresholds obtained by bone conduction are the same as the air conduction thresholds, this indicates that there is nothing stopping the sound from traveling through the outer or middle ear to the cochlea. The new MED-EL Sports Headband provides comfort and security for sports and many other physical activities. Conductive hearing loss tends to a loss of sensitivity across the entire range of frequencies, most commonly in one ear only. In this condition, high frequency outer hair cells tend to die off before low-frequency ones, possibly because the high frequency outer hair cells have to work harder if their job is to amplify acoustic vibrations on a cycle by cycle basis.
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.

This solution is for individuals with conductive and mixed hearing losses, or single-sided deafness. It is a place where you can connect with MED-EL and learn all about hearing and hearing implants. I shadowed my supervisor while she performed audios on different patients and I have gained valuable and useful skills during my observations. It is known as the most common type of hearing loss and more than 90% of people who are hard of hearing have sensorineural hearing loss. A person who suffers from a mixed hearing loss usually has strengths and weaknesses in their hearing. Air conduction: Is the course of sounds that are conducted to the inner ear by way of the outer and middle ear. The reason to do this is to prevent sound from the side being tested from going over to the good side.
However, we test hearing in the range 250Hz to 8000Hz, as most of the sounds of speech occur in this frequency range.
It indicates how much hearing varies from normal and, if there is a hearing loss, where the problem might be located in the hearing pathway. Middle ear conditions caused by Otitis Media can be corrected by medical or surgical treatment.

A conductive hearing loss may also be helped with hearing aids, a middle ear implant or a bone conduction implant.


In the inner part of the cochlea, the apex, the hair cells which are responsible for processing the low tones are still intact. Treatment options may include medication, surgery, hearing aids, a middle ear hearing implant or a bone conduction implant.
This process ensures that without your approval, data will not be transferred to the social networks. I developed a variety of insights on the different degrees and types of hearing losses, differences between air and bone conduction, and the symbols used on an audiogram.
As for the third diagram, I explained what an audiogram is and created a mapping key that is used when performing audio evaluations on a patient.
Someone that has that same hearing for air and bone conduction usually has normal hearing or sensorineural hearing loss.
For example, 250 Hertz (250Hz) sounds like middle C on the piano, while the high pitched ringing of the telephone is about 3000Hz.
Conversational voice level is around 65 decibels, and 120 decibels (120dB) is very, very loud – about as loud as a jet taking off if you are standing 25 metres away!

Combined electric and acoustic stimulation, or EAS, was developed specifically for these cases. Conductive hearing loss can often be medically treated, and in many cases, hearing can be restored.
This type of hearing loss results from a conductive and sensorineural hearing loss mixed together. Someone who has poorer hearing by air than bone eventually has conductive or mixed hearing loss. Noise damage or age related hearing loss tends to produce characteristic deficits as shown in the audiograms here below.
For individuals with permanent conductive hearing loss treatment such as hearing aids or bone-conduction hearing aids may be a feasible treatment option. Once they become damaged they are unable to convert sound vibrations into electrical signals required by the auditory nerve. With this degree of hearing loss the person appears to be able to hear soft sounds, can hear a normal conversation in a quiet room, has difficulty in a noisy environment, and cannot hear whispered conversation or speech from a distance.
During audiogram evaluations the patient wears either headphones or inserts depending on the size of their ear canal for better results. When testing the hearing by bone, patients wear headphones positioned on the temple and cheek.
Unlike conductive hearing loss, which can often be cured, sensory-neural hearing loss is in most cases irreparable, and treatment will aim to make the best use of those auditory structures that remain in tact, perhaps by boosting sensitivity through a hearing aid, or, in severe cases, by trying to bypass dead sensory hair cells with cochlear or brainstem implants. The electromechanical transducer, which converts electric signals into mechanical vibrations and sends sound to the inner ear through the cranial bones.
A person who suffers from this type of hearing loss typically states that they can hear people speak, but not understand what they are saying. A patient with this degree of hearing loss has difficulty hearing a normal conversation in a quiet room, and they must use lip-reading or amplification to comprehend most words. A moderate-severe hearing loss ranges from 55-90 dB HL and a person who suffers from this hearing loss cannot hear a conversation without being spoken loud enough into the ear by the speaker. A patient who has a profound hearing loss ranges from 90+ dB HL, cannot understand speech even if their being yelled at, and they can only hear very loud sounds.
