What are Standing Waves?

Standing waves are acoustic patterns that occur when sound waves reflect between surfaces in a room and interact with each other in a way that reinforces certain frequencies while canceling others.

These waves form when a sound wave reflects off walls, ceilings, or floors and overlaps with the original wave. At specific locations in the room, the waves combine to create areas of strong resonance (peaks) and areas where sound is reduced (nulls).

Standing waves most commonly affect low-frequency sounds such as bass, making some notes sound much louder or weaker depending on where a listener or microphone is positioned. Acoustic treatments such as bass traps and proper speaker placement are often used in studios to reduce the impact of standing waves.
