How Deaf Persons Perceive Sound

These Webpages are no longer maintained. We are keeping the pages here to preserve some of the early years of ProjectDragonfly, to honor the students who created the interactives in the early days of the Web, and because many of the activities are fun and people are still using them. For current Project Dragonfly work, go

Subject: Perceived Sound

Sound waves are perceived by vibrations in the eardrum, which are then sent to the brain in form of codes. The brain understands, detects, and interprets these codes. This process occurs in a matter of milliseconds. Deaf people, however, perceive sound in a different manner, although still using means of vibrations. They are able to detect vibrations through other senses that have become stronger from their weakness in hearing, namely feeling. For instance, some deaf people are able to place their hands on a piano and interpret the varying pitchs and rhthyms through their sense of touch. They feel the vibrations. Similarly, if music from a stereo is playing loudly, it makes the floor shake. The deaf can feel these vibrations and percieve the "sound."
