Description:
With respect to the sound curve upper left, the lower left sound curve has twice the sound pressure (amplitude is twice as high). The upper right curve, however, has twice as high tone (twice the frequency). Bottom right, both the amplitude and frequency have been doubled.The following can be said about a sound curve:
- Amplitude stands for volume.
- The frequency indicates the pitch.
With high tones, the wave shapes are narrow and are repeated quickly, with low tones, the wave shapes are broader and are repeated more slowly.
Information and ideas:
Connection can be made to the curve discussion in Mathematics. To be used on worksheets, transparencies etc.
Relevant for teaching:
Sound/acoustics: parameters
Vibrations and waves
