Certain terminology is used to describe frequency range and sound. The following standards are what will be used on this forum:http://www.independentrecording.net/irn/resources/freqchart/main_display.htmhttp://www.stevehoffman.tv/dhinterviews/HoffLesson1.htm
There may be some personal variances among us, but for the most part, any individual differences should be bridgeable. What is not compatible with our terminology are the odd definitions found in Stereophile's Sound Audio Glossary. For example, Stereophile defines the upper midrange as the range of frequencies from 650-1300Hz. This makes absolutely no sense and we have no idea why they would do this other than to seed further confusion.
Some people have pointed out that the Stereophile definition is preferable because the highest frequency a female voice can reproduce is a little bit over 1kHz. But this is only taking into account the fundamental frequencies. The harmonics of the female voice extend well past 8kHz, and its the harmonics that make a female voice sound different from a violin (which by the way produces harmonics up to 16kHz.)
Whatever rationale used is irrelevant because the purpose is to facilitate transmission of knowledge rather than create misunderstanding. This is why we have chosen a system that audio professionals (and most sane audiophiles) have been using for about 70 years.
