In his book "Mastering Audio: The Art and the Science" by Bob Katz, one of the legends in the recording industry, there is a frequency chart that lists terms such as nasal, boomy, boxy, fat, harsh, roomy, extended, etc. and matches them to specific frequency ranges.

The terms go back to the late 1940's if I remember correctly. I have the book and find it very useful for understanding not just how to describe sound, but how a true audio engineer goes through the process of creating a recording.
Here is the link to the chart page, which may or may not work since it's

Anyhow it's on page 43.
Highly recommended.
