Subject: Re: Audio Quality vs. Expectation From: "Freed, Dan" <DFreed@xxxxxxxx> Date: Fri, 31 Mar 2006 09:56:37 -0800Here's a paper showing that listeners' judgments of loudspeaker sound quality are influenced by knowledge about the price and size of the loudspeakers: Toole, Floyd; Olive, Sean, "Hearing is Believing vs. Believing is Hearing: Blind vs. Sighted Listening Tests and Other Interesting Things", 97th Convention, Audio Eng. Soc., Preprint No. 3894 (1994 Nov.). And here's another showing that in home theater systems, users' impressions of sound quality and their impressions of picture quality influence each other: Woszczyk, Wieslaw; Bech, Søren; Hansen, Villy, "Interaction Between Audio-Visual Factors in a Home Theater System: Definition of Subjective Attributes", 99th Convention, Audio Eng. Soc., Preprint No. 4133 (1995 Sept.). Dan Freed Senior Engineer, Hearing Aid Research Lab House Ear Institute 2100 W.
