| Question | Answer |
| Doppler effect | shift in frequency caused by motion |
| Frequency | sound tells you how fast the pressure oscillates |
| Pitch | different sounds |
| Decibels | loudness of sound |
| Speaker | a device that is specially designed to reproduce sounds accurately |
| Longitudinal waves | air is compressed in the direction of travel |
| Subsonic | moving slower than sound |
| Resonance | spaces enclosed by boundaries,with sound waves |
| Reverberation | multiple echo |
| Fourier's theorem | any wave form can be represented as a sum of single frequency waves |
| Frequency spectrum | a graph that shows the amplitude of each component frequency in a complex wave |
| Sonogram | a special kind of graph that shows how loud sound is different frequencies |
| Cochlea | a tiny-filled organ in the inner ear |
| Rhythm | a regular time pattern in a sound |
| Musical scale | pattern of frequencies |
| Consonance | more than one frequency of sound and the combination sounds good |
| Dissonance | combination sounds bad or unsettling |
| Beat | the phase of the two waves changes in a way that makes the loudness of the sound seem to oscillate |
| Variation comes from | harmonics |
