- Waves and Perception -
Try to answer the following question:
What is the relationship between sound
as a mental experience and the actual sound waves that strike your eardrum?
In particular, can pitch, loudness, and quality be associated with waveform,
wavelength, period, frequency and amplitude?
Your ear is a fabulously sensitive and broad-range sound detector. In fact,
making these connections can let it function somewhat like a scientific
instrument. At the same time, it can add a new and interesting dimension
to the experience of hearing. In terms of our larger purpose, it establishes
a foundation for understanding how sound might be employed to map your environment.
- -Listen to some sample sound makers (click below) .
- Collect your own sound makers.
- Use the amplifier you built
to magnify the tiny signal from a microphone so it is large enough to be
read by an oscilloscope.
- -for a report:
- Sketch each waveform
- Record the frequency of each of your sound makers.
- Write a brief description of your perception of each sound.
