How Do the Physical Properties of the Ears Help the Brain Decode and Interpret Sounds?

How do the physical properties of the stiletto heels help the brain decode and allow sounds? Sound travels as osccialtion by means of some medium. The function of ears is to break up the sound into electric messages which are sent to the brain which perceives and interprets the sound. Ears endure of three parts the out(prenominal) ear, affection and inside ears. The outer ear consists of the pinna which collects the sound and transmits it to the ear canal, which amplifies the sound and transmits it to the tympanic membrane, the stratum between the outer ear and the essence ear. The middle ear consist of tympanic membrane, osiccles (three bones connected in taking over: hammer, anvil and stirrup) and prolate window. When the sound quivering from the outer ear reaches the tympanic membrane it vib positions at the same rate as the vibration from the outer ear. The vibrating tympanic membrane causes ossicles to vibrate, which transmits the vibration to the oval w indow. The sound is amplified when transmitted as the tympanic membrane is a great deal larger then the oval window, and the bigger gist is needful to transmit the vibration from the air module to the smooth alter cochlea of the inner ear. This amplification is also aided by lever-like challenge of ossicles. This helps to permit the loss of sound energy.

Two muscles connected to the ossicles (stapedius and tensor tympani) whitethorn damp down this amplification when tensed to cheer the inner ear from the outgoing noise and self-generated sound. after(prenominal) sound passes through the oval window it reaches the inner ear, which is the inward ! part of the ear. It consists of the fluid-filled cochlea, basilary membrane, organ of corti, tectorial membrane and hair cells. The cochlea consists of vestibular, middle and tympanic canals. later the sound reaches the cochlea, oscillation causes the fluid vibration, which in turn vibrates the basilar membrane, which separates the vestibular and middle canals and contains and supports the organ of corti, which contains...If you lack to get a full essay, order it on our website: BestEssayCheap.com
