Sensorineural hearing loss

Figure 4: Neural tuning curve for normal hearing.

Sensorineural hearing loss (SNHL) is a type of hearing loss, or deafness, in which the root cause lies in the inner ear or sensory organ (cochlea and associated structures)or the vestibulocochlear nerve (cranial nerve VIII)or neural part. SNHL accounts for about 90% of hearing loss reported. SNHL is generally permanent and can be mild, moderate, severe, profound, or total. Various other descriptors can be used such as high frequency, low frequency, U-shaped, notched, peaked or flat depending on the shape of the audiogram, the measure of hearing.
