Hearing loss: is diminished ability to hear sounds like other people do,
Hearing Loss: refers to the inability to understand speech through hearing even when sound is greater than before.
Profound Hearing Loss: means the person cannot hear anything at all; they are unable to detect sound, even at the highest volume possible.
Conductive hearing loss is the result of sounds not being able to pass freely to the inner ear. This usually results from a blockage in the outer or middle ear such as ear infection , ruptured in eardrum, swelling in eardrum, due to swelling of eardrum three tiny bones (the malleus, incus, and stapes) in Auditory ossicles( middle ear) may dislocate not moving freely,
This type of hearing loss is sometimes referred to as sensory, cochlear, neural or inner ear hearing loss. Sensorineural hearing loss is the result of damage to the hair cells within the cochlear or weakness the auditory hearing nerve (or both) ,. Sometimes, the hearing loss is caused by damage to the nerve that carries the signals to the brain.
Sensorineural hearing loss not only changes our ability to hear quiet sounds, but it also reduces the quality of the sound that is heard, meaning that individuals with this type of hearing loss will often struggle to understand speech. Once the cochlea hair cells become damaged.
Degree of hearing loss | Hearing loss range (dB HL) |
---|---|
Normal | -10 to 15 |
Slight | 16 to 25 |
Mild | 26 to 40 |
Moderate | 41 to 55 |
Moderately Severe | 56 to 70 |
Severe | 71 to 90 |
Profound | 91+ |
In which the hair cells inside the cochlea are affected
In which the central auditory processing pathway is affected
Refers to a combination of conductive and sensorineural hearing loss. This means that there may be damage in the outer or middle ear and in the inner ear (cochlear) or auditory
A person with a profound hearing loss will not hear any speech and only very loud sounds.
