According to the Centers for Disease Control and Prevention (CDC)<\/a>, \u201cGenes are responsible for hearing loss<\/a> among 50% to 60% of children with hearing loss.\u201d When hearing loss is present at birth, it is said to be congenital.

There are three types of congenital hearing loss: conductive, sensorineural and mixed.<\/p>\n\n\n\n

Conductive Hearing Loss<\/h3>\n\n\n\n

Conductive hearing loss is caused by a physical blockage in the outer or middle ear that prevents soundwaves from passing through. Possible causes include a physical deformity in the outer ear or fluid in the middle ear.<\/p>\n\n\n\n

Sensorineural Hearing Loss<\/h3>\n\n\n\n

Sensorineural hearing loss results from damage to the inner ear’s sensory cells that convert soundwaves into electrical signals interpreted by the brain, the auditory nerve which sends these signals to the brain or the brain itself.<\/p>\n\n\n\n

Mixed Hearing Loss<\/h3>\n\n\n\n

Mixed hearing loss means both conductive and sensorineural hearing loss are present.<\/p>\n\n\n\n
