Question

PLZ HELP!!!!!! IN YOUR OWN WORDS PLZ! :D

Imagine your cell phone rings. Describe how the sound gets transmitted from your phone to your ear, and then, from your ear to your brain. In your response, be sure to mention the type of wave that a sound wave is, the medium the sound is transmitted through before it gets to your ear, and what happens in your ear once the sound reaches it.

Answer 1

Answer:

Sound waves entering the ear travel through the outer hear-able trench prior to striking the eardrum and making it vibrate. The eardrum is associated with the malleus, one of three little bones of the center ear. Likewise called the mallet, it communicates sound vibrations to the incus, which passes them to the stapes. longitudinal waves are the waves that are being used when transmitting sound. Hope this helps :)

Answer 2

Answer:

SOUND WAVE (carried by thin metal inside the phone) ⇒ELECTRICAL ENERGY (over the wire) ⇒SOUND WAVE (that is heard by someone on the side of the phone)

Explanation:

• What is a sound wave?

A wave that is comprised of compression and refraction, by which sound is propagated in an elastic medium such as air.

• How does sound get transmitted from phone to ear?  

The sound waves are carried to a thin metal disk inside the phone, known as the diaphragm, and are converted into electrical energy. The electrical energy travels over wires to another phone and is converted from electrical energy to sound waves again which can be heard by the one on the other end of the phone.

• How does sound get transmitted from ear to brain and what happens when sound reaches the ear?

1. Sound waves enter the outer ear and travel through a small passageway (ear canal), which leads to the eardrum.
2. The eardrum vibrates from the coming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are known as the malleus, incus, and stapes.
3. The bones present in the middle ear amplify the sound vibrations and send these vibrations to the cochlea (the snail-shaped structure that is filled with fluid present in the inner ear). An elastic separation runs from the beginning to the edge of the cochlea, splitting it into upper and lower parts. This separation is called the basilar membrane as it serves as the base on which key hearing structures sit.
4. Once the vibrations result in the fluid inside the cochlea rippling, a traveling wave appears along the basilar membrane. Hair cells (sensory cells) sitting on top of the basilar membrane ride the wave. Hair cells near the broad end of the cochlea detect higher-pitched sounds. Those closer to the center detect lower-pitched sounds, such as a large dog barking.
5. As the hair cells move up and down, microscopic hair-like projections (known as stereocilia) that perch on the peak of the hair cells crash against an overlying structure and bend down. Bending results in pore-like channels, which are at the tips of the stereocilia, opening up. Then chemicals rush into the cells, producing an electrical signal.
6. The auditory nerve carries this electrical signal to the brain, which in return it into a sound that we recognize and understand.

In this way, sound reaches our ears.
