Does anyone have experience with methods of obtaining judgments of the comparative roughness of beating tones or AM stimuli varying along one or more dimensions? I'm hoping to avoid common pitfalls associated with either instructions or method, and I'd particularly like to find a method amenable to within- and across-group analysis, if such a thing exists. I’m also trying to avoid paired comparisons….
Many thanks for any suggestions.
