Transcript of How does sound travel through a phone?

Presented by Olivia Alger and Lia Neff How does sound
travel through a phone? When you're on a phone and someone is talking, all you're really hearing is a bunch of different vibrations and sound waves. Sound is actually vibrations. But
what are sound waves? First of all, how does a phone work? In order to know how sound travels through a phone, we have to know the basics of the device. Cell towers cover a range of land,
and are connected to other towers
to transfer the signals from a cell
phone. All of the cell towers and stations are connected to a larger network that handles calling and data transfers, such as if you are calling to a different area.
"Sound Waves." Sound Waves. N.p., n.d. Web. 24 Sept. 2012. <http://www.fi.edu/fellows/fellow2/apr99/soundvib.html>. Cited Sources: "Easy Cellphone." How Does a Cell Phone Work? N.p., n.d. Web. 24 Sept. 2012. <http://www.easy-cellphone.com/how-cell-phone-works.htm>. Sound waves are different pitches that your ears hear. The exact definition of a sound wave is:
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air. When you dial a number into your cell phone,
it automatically sends it to the cell tower "base",which transfers the call to the intended person. . . . The compression, where particles crowd together, of the sound wave is shown in the diagram as the upward curves. So...
What do all those confusing words mean? This is a picture of what a sound wave looks like. The rarefaction of the sound wave, when the particles are spread apart, is diagrammed in the picture as the downward curves in the line. "Sound Waves." Sound Waves. N.p., n.d. Web. 26 Sept. 2012. <http://www.fi.edu/fellows/fellow2/apr99/soundvib.html>. The lower the wave frequency,
the lower the pitch. The higher the wave frequency,
the higher the pitch. The more energy, or intensity, a sound wave has, the louder the wave's sound is. Same with the softness and loudness of the
sound wave. The less energy, or intensity, a sound wave has, the softer the wave's sound is. When you speak into a cell phone, the sound waves coming from your mouth are, like the data of a call, sent to the cell tower and transmitted to the phone you are trying to reach. Now that you know THAT,
we can answer the question,
"How does sound travel through a phone?" Sometimes, a mobile phone will put data you are trying to send, such as email, pictures, texts, etc., into little packets. Those packets are then sent over to the cell phone towers, which then transfer them to the phone you are sending the information to. THAT'S HOW SOUND TRAVELS
THROUGH A PHONE. "How Does a Cell Phone Work?" How Does a Cell Phone Work? N.p., n.d. Web. 26 Sept. 2012. <http://www.wirelessforums.org/general-cellphone-discussion/how-does-cell-phone-work-122812.html>.
