The Science of Balance and Hearing

  1. 1. The Science of Balance and Hearing The ears may appear to be just a dangling appendage on your head but they are actually intricate organs responsible for both hearing and balance. The ear has three major sections: 1) the outer ear, which includes theearlobe and ear canal2) the middle ear, comprised of the eardrum and the little earbones and muscles beyond the drum3) the inner ear, which is where things get really interestingThis inner ear portion has a bony structure that is divided into thecochlea, the semicircular canals and the vestibule. Together, thelatter two are constantly working with the rest of your body toadjust and sense your orientation in relation to the pull of gravityon earth. This is whats known as balance.The cochlea transmits the sound vibrations from the ear canaland middle ear into pitches when the sound travels over tiny"hair" cells inside of it. The pitches are then converted intoelectrical impulses that travel to the brain via the cochlear nerve.This branch of science that studies how humans perceive and usesound is called audiology. Since it deals with the body, the field islargely focused in the health care industry where professionalsare involved with identifying, diagnosing, treating and evaluatinghearing disorders. Some of these professionals have a Doctortitle, as 18 states require a Doctor of Audiology (Au.D) degree topractice.All are licensed in the state where he or she practices and mustcomplete coursework at an institution accredited by the Council

Some are involved in developing and designinglistening devices while others focus solely on dispensing or sellingsaid technologies. Researchers in this field are always in need inorder to study and test decibel levels that are potentiallydamaging to the ears. In a world thats increasingly noisy,qualified audiology specialists will always be needed.REFERENCES: For More Information, Call Premium Hearing Solutions At: (248) 686-2586 Or Visit Us At:
