Sound Waves and Characteristics
Amplitude
- Height (loudness) of the wave
- Measured in decibels (dB)
Frequency:
- Number of waves that pass in a second
- Measured in Hertz (cycles/second)
- Wavelength, the length of the wave from crest to crest, is related to frequency
Phase:
- Refers to the point in each wave cycle at which the wave begins (measured in degrees)
- (For example, changing a wave’s cycle from crest to trough corresponds to a 180 degree phase shift).
