-Bei der Interaktion von Lautsprecher und einer reflektierenden Wand kann es bei bestimmten Frequenzen zu Auslöschungen kommen.+The interaction of a loudspeaker and a reflective wall or floor can lead to cancellations at certain frequencies.

-Bei 1/4tel Wellenlänge (λ/4) läuft der Schall zu einer reflektierenden Begrenzungsfläche hindann wieder λ/4 zurückDabei kommt die Reflexion gerade mit insgesamt λ/2 = 180° Phasenverschiebung zurückwas zu einer Auslöschung führt.+At a distance of 1/4 wavelength (λ/4) of the the loudspeaker from a reflective surfacethe sound travels 1/4 wavelength to the surface, another 1/4 wavelength back, for a round trip when it meets the loudspeaker again of 1/2 wavelengthThe reflected sound and the sound emitted by the loudspeaker are 1/2 a wavelength out of phase when they meet(180 degress out of phase) resulting in theoretically complete cancellation.
