| Question | Answer |
| The mechanical or electronic process of making a sound louder. | amplification |
| The continuum of all possible sound frequencies. | acoustic spectrum |
| The scientific study of understanding and controlling how sounds are heard; the acoustic properties of a room or building. | acoustics |
| A non-SI unit of loudness; the ratio of the power of a measured sound to a reference sound expressed on a logarithmic scale. | decibel |
| The biological or artificial use of acoustic echoes to detect distance and direction of objects of interest. | echolocation |
| A sound with a frequency below the range audible to humans. | infrasonic waves |
| The power of a mechanical wave, proportional to the square of the wave’s amplitude; a wave’s rate of energy transmission. | intensity |
| The response of the ear and brain to the intensity of a sound. | loudness |
| The property of an audible sound determined by its frequency. Higher frequencies have higher pitches. | pitch |
| The ear’s interpretation of the mixture of fundamentals and harmonics in a complex sound, as from a musical instrument. | quality |
| An artificial device that either listens passively or uses active echolocation in bodies of water for navigation, research, or military purposes; an informal name for any natural use of echolocation, such as with bats. | sonar |
| The form of wave-transmitted energy detectable by the ear; more generally, energy transmitted through matter by mechanical waves. | sound |
| A sound with a frequency above the range audible to humans. | ultrasonic waves |
| In longitudinal waves, regions of maximum particle density | Compression |
| In longitudinal waves, regions of minimum particle density | Rarefaction |
