Sound and the Ear.


Hello Champions. I hope you got a chance to check out the brainpop on the ear. Here is another website for you to look at: http://school-for-champions.com/science/sound.htm

Great information on sound. Also, we are having a quiz on friday on chapter 2, Sound. If you want to take a practice quiz, there is a self-assessment at PHSchool.com key in Web Code: cga-5020. So, one of the questions we had today in our book was: Explain when a whisper would be louder than a shout. The answer is: Loudness of a sound depends on both intensity and distance. A whisper has a low intensity, but if the distance is small enough it may be louder than a more intense sound that is further away. Here is a diagram of the ear from today.
