A standing wave refers to two types of sound waves with the same frequency and opposite transmission directions, forming a certain distribution state along the transmission direction. One of these waves is generally the reflection of the other. At the point where the sound pressures of the two add up, a wave crest is formed, and at the point where their sound pressures subtract, a wave trough is formed. On the waveform, the positions of the wave troughs and wave crests are always constant, but their instantaneous values change over time.

A standing wave refers to two types of sound waves with the same frequency and opposite transmission directions, forming a certain distribution state along the transmission direction. One of these waves is generally the reflection of the other. At the point where the sound pressures of the two add up, a wave crest is formed, and at the point where their sound pressures subtract, a wave trough is formed. On the waveform, the positions of the wave troughs and wave crests are always constant, but their instantaneous values change over time.
