Auditory and Hearing Experiments
I. Identify these instruments:
II. Auditory ID and Localization:
Have a blind-folded test subject sit in a chair facing away from the tester. Make various sounds from various locations and various degrees of loudness, and have the subject identify the sound and location. Suggested sounds are : clap, snap fingers, whistle, doorbell, knock on door, animal noise, scream, talk softly, laugh, stomp, running water, phone ringing, etc.
Which sounds were harder to hear ? Which sounds were harder to locate ?
III. Balance and Equilibrium
Obtain a 6 foot piece of masking or duct tape, a blind fold, watch, and test subject. Place the tape on the floor and ask the subject to "walk the line". At the end of the tape line, have the subject use their index finger to touch their nose. Record the time it took to completet the tests and their results.
Blind fold the test subject and start them walking the line. Have them touch their nose with their index finger when they think they are at the end of the tape. Let them see how they did. Record the time it took to complete the tasks and record the results: did they finish ?, did they start to fall ?, did they miss their nose ?
Now blind fold the test subject again and spin them around 10 times. Take off the blind fold and have them walk the tape line again. At the end of the line, have them use their index finger to touch their nose. Record the time it took to complete the tasks and record the results.
How important is sight to balance and equilibrium? How fast did the test subject "recover" after being spun around ? How might a person suffering from vertigo feel ?
