Many different conditions can result in hearing impairment and the cause can be located in any part of the hearing system.
Conditions affecting the outer and middle ear cause a a€?conductivea€™ type of hearing loss. Conductive hearing loss may be temporary or permanent, can be caused caused by a buildup of earwax or an ear infection, or other middle ear conditions. The hearing test is plotted on an audiogram which shows the degree of hearing loss (dB or decibel on the vertical axis) for individual frequencies (Hz or Hertz on the horizontal axis).
This is a graph which shows the percentage of correct words repeated on the vertical axis against the presentation level (volume in dB). Include electrophysiological measurement of the auditory system as well as Central Auditory Processing which tests how auditory information is processed, it tests a€?what the brain does with what it hearsa€™. More specific information about your hearing loss can be obtained by having a comprehensive hearing test. HEARLINK is a privately owned and operated audiology clinic committed to helping people hear.
Explore the tabs below to learn more about hearing aids, hearing loss, and find out if you might be a candidate for hearing loss. Sensorineural: Sensorineural Hearing Loss occurs when the sensory part of the ear (the inner ear and outer hair cells) or the neural part of the ear (nerve that runs from the ear up to the brain) lose their ability to function normally. Conductive: Conductive Hearing Loss occurs when there is something physically obstructing the ear canal or middle ear and sound cannot be effectively conducted through the canal and middle ear into the inner ear. Ototoxicity: There are classes of drugs that can harm the hair cells in the inner ear and cause hearing loss.
Noise Exposure: Noise Induced Hearing Loss (NIHL) occurs when people work or play around loud noises for extended periods of time. Physical Trauma: If there is physical damage to the ear or skull, hearing loss can be permanent or temporary due to the damages inflicted to the structures in the ear or brain. Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells. However, there are practical limits to the amount of amplification a hearing aid can provide. Overview - The microphone and tubing of this type of hearing instrument are hidden in the ear's natural contours, so the instrument is virtually invisible in the ear.

Sensorineural hearing loss is another type of hearing loss also known as SNHL or Sensor neural hearing loss. Mixed hearing loss is the type of hearing loss that conductive hearing loss and sensorineural hearing loss is in combination. Conditions affecting the inner ear and the auditory nerve cause a a€?sensorineurala€™ hearing loss or a€?nerve deafnessa€™.
Your outer ear gathers sound waves and funnels them down into the ear canal, striking the eardrum, causing it to vibrate. Sensorineural hearing loss, which is almost always permanent and far more common and be caused by aging, excessive and prolonged noise exposure, infections, hereditary factors as well as a host of other causes. There is usually close correlation between the speech audiogram and the pure tone audiogarm.
This happens to many people as they age and from the “wear and tear” that we put on our hearing. Oftentimes conductive hearing loss is temporary, but there are some medical conditions where it is permanent. There is no gradual loss of hearing; moreover people wake up in the morning and find that they cannot hear out of one of their ears at all.
Certain mycin drugs, as well as chemotherapy drugs, can damage one’s hearing, especially in the high frequency range. Most often the damage occurs in the high frequencies, but leaving the low frequencies within the normal range. The damage can occur as a result of disease, aging, or injury from noise or certain medicines. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. Three tiny bones in the middle ear conduct the vibrations from the eardrum to the cochlea in the inner ear.
Surgical procedures and medications can treat conductive hearing loss, but rarely sensorineural hearing loss. It is not usually considered a measure of hearing but rather it measures the mechanical function of the the middle ear which includes the ear drum and the three ossicles (tiny bones) as well as the ventilating adequecy of the Eustachian tube (for the middle ear to work normally it needs to be filled with air at the same pressure as the outside atmospheric pressure ar any given time including different altitudes).
If a hearing aid is indicated this will also be discussed with your Audiologist or Audiometrist. A few examples of conductive hearing loss are: having wax impacted in the outer ear canal, having fluid in the middle ear (from an ear infection), or having bony growths around or on the ossicles (middle ear bones).


There are some diseases of the ear that present with this symptom, but not all causes of sudden hearing loss are known.
Many doctors will do hearing testing to monitor their patients’ hearing throughout a cycle of chemotherapy. It’s mostly permanent because sensorineural hearing loss’ is very hard to be cured by medicals or surgery. If anything interferes with the transfer of sound waves up to this point the type of hearing loss that may result is called conductive.
However, only about one out of five people who would benefit from a hearing aid actually uses one. The sound vibrations having reached the inner ear create waves in the fluid inside the inner ear, stimulating thousands of delicate hair cells. Also it’s known that some drugs are making toxic effect and creating sensorineural hearing loss. There are lots of researches why depression is causing hearing impairment and it’s known that depression in every age may cause hearing loss. This generates nerve impulses in the auditory nerve, which lies just beyond the cochlea, which are carried to the brain therefore, making sense of sound.
The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. Living troubles on understanding what people say in standard sound is the most known symptom. Anything that damages the hair cells or blocks the transmission of the nerve impulses can lead to sensorineural hearing loss. The amplifier increases the power of the signals and then sends them to the ear through a speaker. Also listening TV on higher than normal volume continuously and depression based hearing loss are the main symptoms of hearing impartibility. Some deep head traumas may cause sensorineural hearing loss and also rarely but aging may cause it.
