- The distance a sound wave travels in the time it takes to complete one cycle.
- The physical distance from a given point of a wave through one complete cycle. How long a wave is. The length of a sound wave determines the frequency of the sound. Can be calculated by dividing the frequency of sound into the speed of sound (for example, a 500Hz sound wave is 2.26 feet long). Source: Church Audio & Acoustics Glossary
- For a periodic wave in an isotropic medium, perpendicular distance between two wavefronts in which the displacements have a difference in phase of one complete period. Unit, meter (m). Source: Glossary of Terms in Noise Control Engineering
- The distance the sound wave travels to complete one cycle. The distance between one peak or crest of a sine wave and the next corresponding peak or crest. The wavelength of any frequency may be found by dividing the speed of sound by the frequency. (speed of sound at sea level is 331.4 meters/second or 1087.42 feet/second).

- The length of a wave based on the propagated wave distance in relation to one cycle. With a wave velocity of 300,000,000 meters per second (approximately 186,000 miles per second), 1 cycle 300,000,000 meters.
