Decent Essays
Amplitude is the amount that air particles are disturbed, also means the “loudness” of sound.
b. The frequency of the soundwave for human hearing can range from 20 hz to 20,000 hz.
c. A transducer is a device that can transfer one type of energy to another. An example of this is headphones.
2. Outer- The outer ear structure has the auricle and the auditory canal. The auditory canal ends at the tympanic membrane or better known as the eardrum. Sound waves that come in the auditory canal hit the tympanic membrane, which then will vibrate.
Middle- The middle ear is only involved in hearing. The middle ear is between the tympanic membrane and the round and oval windows. There are three bones in the middle ear: the malleus, incus and stapes. Vibrations

This is called the theosseous labyrinth. The 3 parts of this are the semicircular canals, cochlea, and vestibule. The cochlea has the vital job of sending electrical signals to the brain. Then the brain takes these signals and transfers the signals into noises and sound.

4.a Static equilibrium responds to head position changes. Maculae is what tells the brain the location of the head. The maculae have tiny hairs called otoliths, which make up the otolithic membrane. When the head moves, otoliths respond to changes in gravity, which pulls on the otolithic membrane. A plate then covers the otoliths, which causes them to bend and send signals to the vestibular nerve. The vestibular nerve tells the brain the location of the head.
b. Inner ear
c. The receptors respond to angular motions. Hair cells called cupulas drags along the endolymph and the cupulas bend. The hair cells are stimulated and the signals are sent to the vestibular nerve. The signals are then sent to the cerebellum, this causes the cupulas to bend the other
