|---|---|---|---|---|---|
| Amplitude | The maximum displacement of the particles of a medium; the distance between the baseline and the maximum displacement.
🗑
|
||||
| Aperiodic Wave | A wave with an absense of periodicity, where it is impossible to predict what the wave will look like from one time to the next. Its vibratory motion is random.
🗑
|
||||
| Complex Wave | Any sound that is not sinusoidal; it itself is composed of a series of simple sine waves that can differ in amplitude, frequency, and phase.
🗑
|
||||
| Energy | The measure of the capacity to do work OR something that can produce a change in matter.
🗑
|
||||
| Fourier Analysis | Takes a complex wave form and decomposes/analyzes it to determine the amplitudes, frequencies, and phases of its sine wave componants.
🗑
|
||||
| Frequency | The number of cycles completed per second.
🗑
|
||||
| Logarithmic Scale | One unit on the scale is so many times greater (or less) than another; successive units are always different by some constant ratio, and the constant ratio always equals the base.
🗑
|
||||
| Period | The time (seconds) it takes for a vibration to complete one cycle of vibration.
🗑
|
||||
| Wavelength | The distance traveled by a sound wave during one period of vibration.
🗑
|
||||
| Waveform | A graph in which changes in pressure or amplitude (displacement), are shown as a function of time.
