Deafness can increase until it is almost impossible to hear any sound, but it has been found that most deaf persons can hear at least one sound. If a person is totally deaf, he cannot hear a thing including his own voice. Some people are born deaf, and some lose their hearing from disease or other causes. Most hearing problems are caused by diseases that do not necessarily start in the ear but reach it from some other part of the body.
Sound and the Deaf community. Deaf people have learned about how sound works, how it travels, and it's volumes. Deaf people actually know a lot about sound, sound plays a role in their lives. Deaf people can not only see how sound works, but they can feel its vibration. Deaf people construct their world around the resources of movement, form, and sound. A huge misconception among hearing people is that Deaf people live in a world without sound.
