Sensorineural hearing loss is often accompanied by ear noise, or tinnitus, which is a high-pitched ringing heard only by the patient. Because the inner ear has no pain fibers, damage is not accompanied by pain. Hearing loss is usually measured by an instrument called an audiometer which measures the weakest intensity at which a person can hear at most frequencies in the range of human hearing. The instrument is calibrated against the lowest intensity heard by normal humans at each frequency, according to an international standard. Audiometry can determine the amount of hearing loss-whether it is conductive or sensorineural in nature, and how much of each type of damage has occurred.
Rehabilitation is available for patients with hearing losses.
There are lots of programs and resources for these people. Most are special schools. One example might be Cleary's School for the Deaf. These schools try to provide an environment that is as close to a normal classroom as possible. As a matter of fact, sometimes they use regular classroom's but they provide special teaching assistants to help individual student's.
