Types of Hearing loss
Hearing loss
What does hearing loss mean?
Majority of the human beings are able to hear sounds from a particular range. An individual is said to have hearing loss when he/she is unable to hear that commonly known range of sounds without any aid.
common types of Hearing Loss
Conductive
When hearing loss is due to problems with the ear canal, ear drum, or middle ear and its little bones.
Sensory Neural
When hearing loss is due to problems of the inner ear, also known as nerve-related hearing loss.
Mixed
In this type of hearing loss, there may be damage in the outer or middle ear and in the inner ear (cochlea) or auditory nerve.
Degrees of Hearing Loss
Mild hearing loss
With a mild hearing loss difficulty will occur for soft speech and listening in background noise.
Moderate hearing loss
With a moderate hearing loss one experiences difficulty hearing conversations, especially while in background noise. The TV or radio may be turned to higher levels also in order to be heard clearly.
Moderately severe hearing loss
For a person with a moderately- severe hearing loss, clarity of speech is significantly reduced and the most difficulty will occur in groups.
Severe hearing loss
Loud speech is also difficult to hear or understand. At this point people with severe hearing loss will only hear if speech is shouted or amplified for them.
Profound hearing loss
At this level, people with profound hearing loss may have difficulty understanding even amplified speech.
