I don't quite understand your first ...Hi Ben,<br /><br />I don't quite understand your first statement. The CU accuracy ratings are based on acoustical measurements made in an anechoic chamber; they are not perceptual measurements based on listening tests. So we cannot test whether our listeners can replicate the CU measurements since one is a perceptual measurement and the other is an acoustical measurement.<br /><br />We test our trained listeners against untrained listeners from time to time, and find they are not "biased" towards a certain sound. The trained listeners have similar loudspeaker preferences as a group of 300+ untrained listeners as documented in this study.<br /><br />see http://seanolive.blogspot.com/2008/12/loudspeaker-preferences-of-trained.htmlDr. Sean Olivehttps://www.blogger.com/profile/17909033506833141612noreply@blogger.comtag:blogger.com,1999:blog-7172143857693272648.post-24770267515429930442010-07-14T12:36:33.872-07:002010-07-14T12:36:33.872-07:00Interesting.

I am wondering if the training "taught" the panel to like a certain kind of sound?<br /><br />BenUnknownhttps://www.blogger.com/profile/08594925011657120486noreply@blogger.com
