Find the first resonant bass modes of a rectangular room.
Every room dimension has a fundamental resonance at a frequency set by half its wavelength, with the longest side ringing lowest. Bass builds up unevenly at these modes, so knowing them guides speaker and listening positions plus bass trap placement.
Room Axial Modes
Axial mode = speed of sound / (2 x dimension)
Axial mode = speed of sound / (2 x dimension) Every room dimension has a fundamental resonance at a frequency set by half its wavelength, with the longest side ringing lowest.
Bass builds up unevenly at these modes, so knowing them guides speaker and listening positions plus bass trap placement.
This calculator takes 3 inputs: Room length, Room width, Room height. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
