Task A: What’s inside the human ear? Label the diagram on the back of this page.

Task B: Explain how you hear your cell phone ringing by tracing the sounds waves produced by the cell phone to interpretation of the sound waves by the brain. You may represent your answer with a written paragraph, a drawing, a rap, or a poem.

Task C: As sound waves travel into the ear and on their way to the brain, how many different energy transformations occur? Describe where and how each transformation takes place.

Task D: What other important job does the human ear do beside interpreting sounds? Explain.

Task: Use the web sites above to answer the questions below

1. What does SONAR really stand for?

2. How many basic types of sonar are there and define them.

3. What is commercial sonar use for?

4. How is the distance between sender and object to be located calculated using active sonar.

5. What is the speed of sound in water?

6. If it takes two seconds for sound to reach the object, we can assume the object is 2 sec x 1,500 m/sec or 3,000 meters away.

Using the above information as a reference assume you are a commander of a submarine during war time and you are searching for an enemy sub to sink. You send out a single due east and you get back a loud return 6 seconds later that the sub is in that direction. You have to set you torpedoes to go off after they travel the correct distance otherwise they could explode before impact. How many meters is the sub to your east?

7. Define echolation.

8. What animals other than bats use echolocation?

9. How sensitive is echolocation?

10. Why is echolocation helpful?

1. Define the doppler effect.

2. Who is responsible for the discovery of the doppler effect?

3. Buys Ballot confirmed that sound pitch was ______that the emitted

Frequency when the sound source ______him and ______that the

Emitted frequency when the sound source ______from him.

4. The received frequency is ______(compared to the

emitted frequency) during the approach, it is ______at

the instant of passing by, and it is ______during the recession.

5. The frequency of the sounds that the source emits does ______actually change.

6. Explain frequency as it relates to wavelength using the analogy of the baseball thrower in motion. See doppler effect link.

7. Illustrate what the wavelengths of a circular sound source look like when stationary, moving at normal speed, moving a mach speed, and when breaking the sound barrier. Try the link more doppler.

8. In the animated cartoon what did the trains horn sound like as it approached you

and when it passed you?

9. Play with the animated doppler- what did you notice about the sound waves when you moved it slow and when you moved it really fast?

10. Read how police doppler and weather doppler radar work using the how doppler

works link and write a summary of how each works in your own words.
