A hearing impairment signifies a full or partial loss of the ability to detect or discriminate sounds OR A person who cannot hear at or about a certain intensity is termed as hearing impairment

Organic Hearing Loss Hereditary Hearing Loss Congenital Hearing Loss Acquired Hearing Loss Pre Lingual Hearing Loss Post Lingual Hearing Loss Sudden Hearing Loss Progressive Hearing Loss Conductive Hearing Loss Sensori Neural Hearing Loss Mixed Hearing loss

The term organic hearing loss Defect in auditory system resulting in organic hearing loss (that may be in external ear, middle ear or in the auditory nerve)

The hearing loss caused by factors present in the genetic make up of the fertilized ovum

Congenital hearing loss means the condition of hearing loss existing since birth Congenital hearing loss may be hereditary or may develop during prenatal or natal period

The term indicated that the hearing mechanism was normal at one time and hearing loss developed at a later stage due to some reason like sever illness, accidents etc.

The term per-lingual indicates that hearing loss developed prior to the language learning age. The hearing loss developed during the first three years of life is considered as pre lingual hearing loss

The term post lingual hearing loss indicate that the hearing loss developed after the language had developed. Post lingual hearing loss can be sudden or progressive in nature

Sudden hearing loss results due to one time insult to the auditory system. The damage to the auditory system results as a permanent hearing loss

Hearing loss is getting worse with time. This may be due to the infection or hereditary disorder The disorder of hearing can result from defects of diseases in outer middle or inner ear or auditory nerve

Any dysfunction of the outer or middle ear in the presence or a normal inner ear is termed as conductive impairment. The acquired hearing losses in children are more likely to be of the conductive type. The conductive hearing loss can be congenital (i.e. loss existing since birth)or acquired due to some reason(i.e. illness, accident)

When the loss of hearing function is due to pathology in the inner ear or along the nerve pathway from the inner ear to the brain stem. The this loss is referred as sensori neural impairment.

Is the combination of both conductive hearing loss and sensori neural hearing loss
