Hearing loss (also known as deafness) refers to an individual’s inability to hear with one or both of his ears. Sometimes the loss can be slightly reversed with the help of a hearing aid, which amplifies sound as it travels through the ear canal. A doctor will need to run some tests and determine the source of deafness before it can adequately be treated.this post
Conductive Hearing Loss
When sound has trouble traveling to the inner ear, it’s called conductive loss. This type can easily be corrected medically or with surgery. If not, an aid will be very effective since the sound from the outer ear needs to be amplified in order to reach the inner ear. This type of loss is most often caused by problems with the ear canal, the eardrum, the middle-ear cavity, the openings that lead to the inner ear, or the Eustachian tubes.
Sensorineural Hearing Loss
The cochlea of the inner ear has close to 30,000 nerve endings, which are required for hearing a wide variety of sounds. Loss due to damaging these nerve endings is irreversible in most cases. Doctors refer to this type as “nerve deafness’ or “retrocochlear” loss.
Central Hearing Issues
Interestingly enough central loss does not actually stand for typical loss, rather an auditory processing problem. Individuals with this issue have no problem with their hearing; in fact, their ears are working over time! They have a hard time filtering out background noise or concentrating on reading or their own conversation when others are talking around them, the radio is playing, or a movie’s playing on the TV.
Currently there is no treatment for central loss, and an aid will only amplify the problem! The best way to deal with this auditory processing problem is to ensure the individual has a quiet place to study, read or carry on a conversation.
Functional Hearing Loss
When hearing “loss” is due to a psychological or emotional issue, it’s referred to as functional hearing loss. An individual suffering from this condition can actually hear perfectly, but they often fail to respond to the one who is talking to them – thus it appears that they cannot hear. In reality, no damage has been done to the hearing pathway; the individual’s emotions and thoughts have trapped him, so he is often unable to respond in even the most simple of conversations.
This issue can be incredibly hard to diagnose. When misdiagnosed, the resulting treatment can actually aggravate the problem and cause the individual to become even more resistant to the right kind of treatment.
Mixed Hearing Loss
Many times, an individual will be diagnosed with more than one form of loss. Typically the term “Mixed Hearing Loss” is used only when both conductive and sensor neural problems combine to cause significant loss. Since the conductive type is easiest to tree, this will be treated first, most likely with a hearing aid, and then the sensor neural loss will also be treated, if possible. If you suspect any type of hearing issue, be sure to talk to your doctor. Many types of conductive hearing problems may be treatable, either through medicine or with the help of a hearing aid.
