The Great Debate...and Then Some

The Great Debate...and Then Some

"Some say it dates back to 1927, when <I>Gramophone</I> magazine's editor thundered that electrical reproduction was a step <I>backward</I> in sound quality," said the promotional copy for Home Entertainment 2005's opening-day event, "The Great Debate: Subjectivism on Trial." It continued: "But whenever it started, the Great Debate between 'subjectivists,' who hear differences among audio components, and 'objectivists,' who tend to ascribe such differences to the listeners' overheated imaginations, rages just as strongly in the 21st century as it did in the 20th." On April 29 at the Manhattan Hilton, <I>Stereophile</I> editor John Atkinson and one of the Internet's most vocal audio skeptics, Arnold B. Krueger, debated <I>mano a mano</I> where the line should be drawn between honest reporting and audio delusion.

If you missed <A HREF="http://www.stereophile.com/features/105kh">Part 1 of this article</A> (<I>Stereophile</I>, January 2005), or it has faded in your memory, here's a r&#233;sum&#233;. (Readers who recall Part 1 with crystalline clarity, please skip to paragraph four.) The accurate measuring of loudspeakers requires that the measurements be taken in a reflection-free environment. Traditionally, this has meant that the speaker be placed atop a tall pole outdoors or in an anechoic chamber. Both of these options are hedged around with unwelcome implications of cost and practicality. To overcome these and allow <I>quasi-anechoic</I> measurements to be performed in normal, reverberant rooms, <I>time-windowed measurement</I> methods were developed that allow the user to analyze only that portion of the speaker's impulse response that arrives at the microphone ahead of the first room reflection. MLSSA from <A HREF="http://www.mlssa.com">DRA Labs</A> is the best-known measurement system to work on this principle, and both John Atkinson and I use it in the course of preparing our loudspeaker reviews.
