Check Room Modes

Room Modes

Room Modes are frequencies that fit exactly between opposing surfaces. In relation to a Control Room or Live Room, Room Modes are present between wall, floor or ceiling surfaces.

When a Room Mode can fit multiple times between a wall, floor or ceiling surface they are classed as duplicate Room Modes. When duplicate Room Modes are present they can produce reflections and flutter (springy sounds) within the room.

As Room Modes are similar to Standing Waves, if duplicate Room Modes are present, Standing Waves can also form and produce an uneven acoustic response within the room.

Peaks and Dips

Duplicate Standing Waves between wall, floor or ceiling surfaces create peaks in the acoustic response of the room. However, if the same Standing Wave is present in the exact area on another axis in the room then phasing is introduced which cancels out that frequency which creates a Dip in the acoustic response of the room.

The idea is to have no duplicate Room Modes / Standing Waves in a room so that the acoustic response of the space is as flat as possible.

Other factors that can also affect the acoustic response of a room or the space between the Room Modes and what frequencies are unable to fully develop or open out within the room. 

Room Mode Spacing is very important, as the distances between low frequencies can be noticeable above 20hz. Basically the tighter the Room Modes are packed together the harder it will be for your ears to distinguish between Room Modes.

Frequencies that aren’t able to fully open out within the room will also appear as Dips in the acoustic response, obviously,when it comes to small rooms, this is unavoidable, however, when it comes to larger spaces, adding an extra 100mm could make all the difference to achieving that all-important flat acoustic response within the room.

Selecting “Room Modes” will check the dimensions you provide to see what Room Modes are present in the room. This calculation checks for Duplicates - Axial – Tangential – Oblique Room Modes. It also calculates the spacing between Room Modes.

Room Shape

Room nodes can only be exactly calculated with room shapes that either have rectangular or square shapes and have parallel walls (including the ceiling). However, if the room has "none parallel" walls, providing the average dimensions (the middle of a "none parallel" surface) can help you understand what is going on in your room.
