Title: HEARING LOSS
1 HEARING LOSS
- Everyone knows what is hearing. Hearing is the
important part of our life and we know that
hearing is only the feeling. It does not exist
physically. But there are some people that cant
hear or hear mild. Problem in hearing the sound
is called the Hearing loss. Hearing loss is also
known as the hearing impairment. Hearing
impairment means the problem in the part of one
ear or ears. This problem occurred as the age
increases. As we know that 10 million of people
in America having the problem in hearing.
2HOW HEARING WORK?
- As we know that our ear is divided into the three
sections - Outer ear
- Middle ear
- Inner ear
- Source- Hearing Loss
3- Outer ear Outer ear receives the waves from
the outside environment and then transfers them
into the middle ear through the ear canal. - Middle ear Middle ear receives these waves
and these waves hit the eardrum in the middle
ear. Eardrum starts to vibrate and generates the
three tiny bones in your ear. - These bones are called hammer, anvil, stirrup .
- Inner ear - In the Inner ear the sound is
generated with the help of these tiny bones. - Source- Hearing Loss
4CATEGORIES OF HEARING LOSS
Hearing Loss Differs people to people. There are
various categories of Hearing Loss. It ranges
from mild to severe to profound. Mild Hearing
Loss is when a person finds it difficult to keep
up with soft conversations in loud/noisy
surroundings. Moderate Hearing Loss is when a
person can not listen to the moderate speech in
noisy surroundings. Severe Hearing Loss,
wherein a person cannot hear loud speech without
the usage of hearing aid. The last level is
Profound Hearing Loss, which means difficulty in
hearing even with the usage of hearing aids.
5TYPES OF HEARING LOSS
- Conductive Hearing Loss
- Sensorineural Hearing Loss
- Mixed Hearing Loss
- Neural Hearing Loss
6CONDUCTIVE HEARING LOSS
- Conductive hearing loss occurs when there is a
problem with the way sound is conducted to the
inner ear or cochlea. - The problem may lie in the outer ear (pinna or
ear canal), eardrum (tympanic membrane).
7SENSORINEURAL HEARING LOSS
- Sensorineural (sen-sory-nuhral) hearing loss
occurs when there is a problem with the sensory
receptors of the hearing system, specifically in
the cochlea of the inner ear. - Sensorineural hearing Loss occur in the inner ear.
8MIXED HEARING LOSS
- Mixed hearing loss occurs when a person has an
existing sensorineural hearing loss in
combination with a conductive hearing loss. - It is, very literally, a mix of sensorineural
and conductive hearing
9NEURAL HEARING LOSS
- Neural hearing loss occurs when the auditory
nerve that carries impulses from the cochlea to
the brain is missing or abnormal. - It is difficult to determine the exact location
of neural hearing loss.
