Room Mode

A ‘Room Mode’ is a resonant frequency that builds up inside of a room (or any container) when sound is emitted at the appropriate frequencies.

Room modes are dependent on the acoustic shape and measurements of the room in that different frequencies, which have different wavelengths, will fit either perfectly or imperfectly within the room’s dimensions.

When waves interact with a hard surface and bounce across multiple surface, there is eventually a feedback loop of that frequency. The overlapping of these frequencies can cause complete cancellations, double amplifications, or anywhere in between.

Room modes are responsible for shaping the perception of a sound and the reason for sound treatment in professional mixing rooms and studios.
