Room modes

Standing wave phenomena can also occur in a room at specific frequencies called the resonance frequencies of the room. These depend on the dimension and shape of the room. At resonance, the acoustic response of the room will be enhanced. As shown by these animations, pressure maxima (in red) and pressure minima (in blue) will then be regularly distributed within the room and their pattern will differ for each resonance frequency. Again the particle distribution has been exaggerated. Notice once more that at the walls, where there is no particle displacement, the pressure is at a maximum.
