Sound In Our Ears

Ever wonder if animals can even hear us talking very well? Well, frogs for example can actually hear better than us humans. The Chinese frog can actually tune their ears like a radio dial. They can even block sounds within certain ranges. When the frogs close their Eustachian tubes they hear high frequencies. The Eustachian tubes are two narrow tubes that connect the mouth cavity to the left and right ear. When these tubes are closed, their sensitivity to low frequencies increase. I believe they have so well because they life in such a noisy environment. These are just things I have found about animals, but you can always fine more information.

The Pitch of Our Vocal Cords

When we speak we have these vocal cords in our throats that vibrate. The number of vibrations per second determines how the pitch is. How do we determine how loud it is? Well, that depends on the strength of the vibration. Small vocal cords have high sounds, and large vocal cords have low sounds. For example its like a guitar, the skinny strings make high sounds, and the fat strings make low sounds. On this website http://www.pbs.org/weta/roughscience/series2/challenges/sound/ you can read a little bit about how our ears can hear the vibrations from our throats, and how they calculate how the pitch and the strength of the vibrations are.
What happens to our vocal cords as we get older? Well as we grow our vocal cords grow making it's sounds lower. When your vocal cords get bigger, the larynx does too which is the voice box. When it does that sometimes it grows so big it bulges out making an Adam's apple. Whether or not you get an Adam's apple it doesn't really matter cause it just has to do with DNA.

Introduction to Surges and Sounds

Dear readers,

Welcome to my blog of surges and sounds! I will be focusing on how we transfer information wirelessly in the world, and how today we are still trying to figure out how to make it even easier. I will focus on how it was started, what countries mostly use the wireless transmission, and just what it is. We all do it through texting, the Internet, and many other things. How we make them go from phone to phone and computer to computer is another question I am looking forward to answer. In radio talkshows they use soundwaves to connect with the whole world. This is just a little bit of what I will be talking about in my blog.
