A conductive hearing loss occurs when there is a problem with a part of the outer or middle ear that stops sound from traveling into the ear and down the ear canal (Schwartz 2007).
Sensorineural hearing loss
A sensorineural hearing loss occurs when there is a problem with the cochlea or auditory nerve located in the inner ear. The cochlea Abnormalities and diseases are the common causes of sensorineural hearing losses (Schwartz 2007).
Mixed hearing loss
A mixed hearing loss occurs when there are signs of both conductive and sensorineural hearing losses (Schwartz 2007).
Auditory neuropathy
Auditory Neuropathy, also known as Auditory Dys-sychrony or AN/AD, is a condition in which the auditory nerve in the ear cannot combine all of the nerve fiber impulses in the inner ear (Schwartz 2007).
Prelingual hearing loss
A prelingual hearing loss is one that occurs before a child learns speech or language skills (Schwartz 2007).
postlingual hearing loss
A postlingual hearing loss is one that occurs after a child has started learning speech and language skills (Schwartz 2007).
Genetic hearing loss
A genetic hearing loss occurs when there is an abnormal gene present in one of the 46 chromosomes of the human body. This type of hearing loss can be passed down to future generations (Schwartz 2007).
Non genetic Hearing loss
A non genetic hearing loss can be caused by incomplete or abnormal development of the ears before birth or damage to the ears during or after birth. This type of hearing loss cannot be passed down to future generations (Schwartz 2007).
