The main shortcoming with using ITU-R BS.2399-0 to discuss sound quality is its use of some words with previously established meaning that don’t immediately confer an understanding to a naive audience of what they mean in the context of audio—and several others with insufficient distinction between different concepts. It’s extremely difficult to serve the needs of a novice reader while also using this lexicon because almost all of terms have very different understood meanings. Though most of the words used to describe things like signal-related issues and noise are easy to understand without a formal introduction to the standard, several others are… not. Things like describing bass as “boxy” or midrange as “nasal” won’t always be well understood by people wondering if they should buy one particular set of true wireless earphones. It’s just not in their lexicon.
When a term isn’t in someone’s lexicon, most won’t even look it up: they’ll attempt to figure it out by context clues—which doesn’t help here. Even if you were to try to look up one of the terms in the standard, it’s not always easy to find because these particular definitions can’t be found in a dictionary. Because readers are encountering words they already recognize in a new context, they’ll try to reconcile their existing understanding of the concept with this new use. Consequently, the logic errors of amphiboly and equivocation are virtually guaranteed among readers who aren’t familiar with the lexicon above, and are trying to determine what the heck they just read. For example: they may take “bright” to mean “good” and “dark” to mean “bad” when the intended meaning has to do with emphasis in bass and treble—neither good nor bad.
Loss of specificity in words can lead to really bad misunderstandings (think “flammable” vs. “inflammable,” “figurative” vs. “literal”), so we avoid it as much as possible. While I am no prescriptive grammarian, I don’t believe words used in unrelated contexts are the best choice in writing—nor do the largest search engines. Grammar isn’t directly policed by search engines, but bad grammar and technical writing mistakes are a strongly negative thing to have in a user experience, which does impact your ranking. Since the vast majority of anyone finding your site through search isn’t going to be at the same expertise level as someone who is familiar with the latest ITU standards, any conflict with someone’s understanding of a word is going to hurt in one way or another.
