Trevor Cox recently published the results of an online experiment about listeners' ratings of sound files on a six-point scale ("not horrible", "bad", "really bad", "awful", "really awful", and "horrible"). To date he has 130,000 subjects (!) and about 1.5 million data points: http://www.sea-acustica.es/WEB_ICA_07/fchrs/papers/ppa-09-003.pdf Here's the website for his experiment: http://www.sound101.org Clearly this is related to the "effect of visual stimuli on the horribleness of awful sounds" that Kelly Fitz pointed out. -Matt On Jun 29, 2007, at 12:32 AM, Massimo Grassi wrote: > So far it looks that the experiment with the largest N (513!) is > "The role of contrasting temporal amplitude patterns in the > perception of speech" Healy and Warren JASA but I didn't check yet > the methodology to see whether is a between or a within subject > design.
