The first time when I heard about "Teen Buzz" was in middle school. My cousin told me that he downloaded a new ringtone which could not be heard by adults. We tested in a car where there were me, my cousin, my aunt, and my parents. He turned it on and a sort of "squeezing sound" filled the car. Surprisingly, none of the adults recognized the ringtone. The "teen buzz" ringtone soon became a trend among teenagers. I could often hear the "squeezing sound" during class from someone's phone. Students could recognize it but not teachers. At first, it was interesting, but after awhile it became annoying and distracting. Listening to those "squeezing sounds" several times during a day often caused headaches too; some people like me hated it. Anyway, the trend soon disappeared. The basic concept of this ringtone was hearing range of humans. Humans can hear sounds from 20Hz to 20,000Hz. We learned from lecture that this range becomes narrower as we get older.
As I proceeded searching, I started to wonder how other organisms perceive the world. Would "their world" be same with "our world"? The answer was no. For example, dragonflies see the movements in slow motion due to their fast brain processing speed. It seems that each organism possesses senses that are the most appropriate for its life style. But what if humans can perceive the world like others creatures, for example insects? It will be fascinating that we will be able to see things that we cannot see with our human eyes.

How do you think the differences in people's hearing affect their perception of the world?
First I'd just like to say that I agree with you, that "Teen Buzz" was really obnoxious and I'm glad the trend is over. The idea that different animals see the world differently than we do is really interesting! I found and article about how reef dwelling animals perceive their world, and I thought it was kind of crazy. I can't imagine what life would be like if we saw the world like this!
