Document Summary
Hearing plays an important role in the manner by which most people acquire speech and language. Children who are deaf and hard of hearing receive special education and related services under the category of hearing impairments. A child who is deaf cannot use hearing to understand speech. Normal hearing = person has sufficient hearing to understand speech; can interpret speech without using any special device or technique. Most deaf people perceive some sounds through residual hearing. Children who are hard of hearing can use their hearing to understand speech: usually with the help of a hearing aid. Ear gathers sound (acoustical energy) from the environment and transforms the energy into neural energy, allowing it to be interpreted by the brain. Outer ear external ear and auditory canal. Auricle (also known as the pinna) part of the ear we see; funnels sound waves into the auditory canal and helps distinguish the direction of sound.
