Abstract	Duplex perception has been interpreted as revealing distinct systems for general auditory perception and speech perception. The systems yield distinct experiences of the same acoustic signal, one conforming to the acoustic structure itself and the other to its source in vocal-tract activity. However, this interpretation has not been tested by examining whether duplex perception can be obtained for nonspeech sounds that are not plausibly perceived by a specialized system. In 5 experiments, some of the phenomena associated with duplex perception of speech are replicated using the sound of a slamming door. Similarities between 26 university students' responses to syllables and door sounds are striking enough to suggest that some conclusions in the speech literature should be tempered that (1) duplex perception is special to sounds for which there are perceptual modules and (2) duplex perception occurs because distinct systems have rendered different percepts of the same acoustic signal.
