Were Those Ears So Golden? (DCC & PASC)
The whole field of subjective audio reviewing—listening to a piece of equipment to determine its characteristics and worth—is predicated on the idea that human perception is not only far more sensitive than measurement devices, but far more <I>important</I> than the numbers generated by "objective" testing. Subjective evaluation of audio equipment, however, is often dismissed as meaningless by the scientific audio community. A frequent objection is the lack of thousands upon thousands of rigidly controlled clinical trials. Consequently, conclusions reached by subjective means are considered unreliable because of the anecdotal nature of listening impressions. The scientific audio community demands rigorous, controlled, blind testing with many trials before any conclusions can be drawn. Furthermore, any claimed abilities to discriminate sonically that are not provable under blind testing conditions are considered products of the listeners' imaginations. Audible differences are said to be real only if their existence can be proved by such "scientific" procedures (footnote 1).
