Dear List members, We are currently working on an experiment about the semantical processing of environmental noises. We are trying to do a similar task as the lexical decision task with words and nonwords, but with environmental noises and "non-noises". The problem is that we have a hard time creating non-noises which are quite environmental noise-like, but are not recognizable. We tried almost every distortion methods used in the literature (reversing, spectrally-rotating, scrambling the parts) but the sounds are always pretty much recognizable by most people. Does anyone have any idea on how to create such non-recognizable non-noises based on existing environmental noises? Or is this idea just not feasible, because people will always think that what they heard is something real?
