Ett starkt ljud kan maskera ett svagare ljud som kommit alldeles innan det starkare ljudet. Sant eller falskt?
Jag antar att vi talar om (mänsklig) hörsel? I så fall:
Sant. Fenomenet kallas backward masking eller pre-masking. Se exempelvis

Although many studies of backward masking have been published, the phenomenon is poorly understood. The amount of backward basking, obtained depends strongly on how much practice the subjects have received, and practiced subjects often show little or no backward masking (Miyazaki and Sasaki, 1984; Oxenham and Moore, 1994). The larger masking effects found for unpracticed subjects may reflect some sort of "confusion" of the signal with the masker.
