Sound - Edward R, Ben, Edward T

Hearing is the universal alerting sense in all vertebrates. Sound is so important because animals are able to hear events all around them, no matter where their attention is focused. Sound is also a vital transportation / communicaiton method used by humans / animals alike. Bats pick up ultrasound emmited by themselves to travel and hunt. Dolphins identify prey and objects by using ultrasound. Humans communicating by using sound which becomes the basis of all language.

Sound is a 360 sense. It has the most coverage out of all the senses eg. you may hear an explosion from a long distance away but you may not be able to see it, smell it, or taste it. It isn't primarily focused in one certain direction at one time. For example if a car was coming at you from behind and you were deaf you wouldn't know that it was there and you would be run over. But with sound you would hear it coming and dive out the way. Sound is also a vital part of music as it is very influential to the sub-conciousness of the human mind. If you only had 1 sense left, sound would probably be the most effective sense to live off of. eg. blind people can hear the world in strange ways.

FUN FACTS :D D: :D

- In Africa, a tribe of people call Maabans live in such quiet that they can hear a whisper from across a baseball field ‹ even when they are very old.
- Sound travels at the speed of 1130 feet per second, or 770 miles per hour.
- At 115 dB, a baby's cry is louder than a car horn.
- It does not matter if you like the sounds you are exposed to. An orchestra playing Mozart at 120 dB will damage your hearing as quickly as Metallica playing at 120 dB.
- The hearing of a dog is more sensitive than humans. Dogs can hear much higher frequencies, which is why they respond to "silent" dog whistles.
