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.

Cheap Priced, Discount Price, Digital Hearing Aids for Severe Hearing Loss Hearing aids are not indicated for an ear with minor hearing loss, and are also not very useful in an ear with profound hearing loss. Hearing Aid Forum > Bluetooth Hearing Aids Hi I currently wear Octicon Epoq WX with a power mould.
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. Patients with profound sudden sensorineural hearing loss (SSNHL) have a poor prognosis regardless of the type of treatment they receive.

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.

Most hearing aids are not implanted (although some bone-conduction hearing aids Answers to many frequently asked questions on hearing aids. I have to admint they do an amazing job and I'm very If a student has a hearing aid, they are likely to hear a lot of unwanted noises. I plan to purchase a mid to premium hearing I wear Oticon Sumo DMs and am People who suffer from severe hearing loss will benefit from powerful hearing aids, but often they rely heavily on lip-reading even when they are using hearing aids. 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, there is evidence that a proportion of patients with profound hearing loss may exhibit variable degrees of recovery, and this has yet to be specifically investigated.
Further, the accuracy, currency and completeness of the information available on this Web site cannot be guaranteed. FOR MORE INFORMATION If medicine or surgery are unsuccessfully, conductive hearing loss can be treated with amplification including different types of hearing aids.
I have a severe-profound, bilateral hearing loss and use hearing aids and speech reading (watching the movement of a person's lips) to maximize my communication abilities.
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. Here, we report a comparison of levels of hearing improvement in patients stratified according to their level of hearing threshold before treatment.

If you have never worn a hearing aid before, you probably are unsure how to describe your hearing loss.
I want to hear better without(and with) hearing aids, especially in the high The Vanderbilt Hearing Aid Report. 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.
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. We compared improvements in hearing threshold at different frequencies and recovery rates between the three groups. The electromechanical transducer, which converts electric signals into mechanical vibrations and sends sound to the inner ear through the cranial bones. No significant differences were observed in hearing threshold improvements at different frequencies in the three groups after treatment. 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. However, in the group with an initial hearing threshold of ?100 dB, significantly less complete and partial recoveries occurred compared to those in the 80–89 or 90–99 dB groups.
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. Our results suggest that initial hearing threshold in excess of 100 dB alters the likelihood of satisfactory recovery in patients with severe to profound SSNHL.
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.
