| Meeting Notice | Welcome to the AES Chicago Section website. Audio Mythbusting The next meeting of the Chicago section of the Audio Engineering Society will be held September 16th 2008, at Shure Incorporated, 5800 Touhy Ave, Niles, Illinois. Members and non-members are welcome. Tom Nousaine will give a presentation on audio myths. There is a tendency for mythology to blend into performance claims in modern consumer product categories. This is especially true for audio equipment at least partly because reproduced sound can easily be demonstrated to have magical properties. Take the stereo phantom center image, for example. One knows that there is sound being generated by the left and right speakers because one can hear and even feel the speakers vibrating. But one can also hear an image between them even though one “knows” that no sound is being produced there. In other words, the normal human hearing mechanism has been defeated. Thus it is relatively easy for people to psychologically invent sound quality attributes that are not factually present and to market and sell products based on those qualities. Indeed, consumer and audio equipment merchandising is often based heavily on mythology. Tom Nousaine has spent over 20 years examining audio Truth and has found the mechanisms for developing Audio Urban Legends, the natural human bias characteristics that allow this to happen. He will discuss a number of Urban Legends which are false but continue to be re-discovered in normal discourse. Some common audio myths include: • Products Need to be Broken In • Small Amplifiers Burn Out Tweeters • Special Wires or Parts Improve Sound Quality • All Amplifiers Have their Own Special Sound Quality • High Resolution Audio Improves Sound Quality • Vinyl Recordings Sound Better Than Compact Disc • Vacuum Tube Equipment Sounds Better Than Solid State • Data Reduction is Always Bad • Equalization is Always Bad • Analog is Always Better than Digital Dinner (optional) will begin at 6:30pm. Reservation required, contact Treasurer Mike Lester at lester_michael@shure.com by Monday, September 15 to RSVP. Pizza will be provided. Price is $7 for nonmembers, $5 for members and students.
