minimze ambiguity when describing audio components


i have noticed and i myself am guilty of using adjectives when trying to describe the "sound" of audio components.

the words, warm, bright, dull, dark, to name a few are ambiguous terms for two reasons.

first, we hear differently. when serious listeners are evaluating the sound of audio equipment, several opposing terms may be used to describe the same component. secondly, without a definition of a term, a word may have different meaning when used by serious hobbyists.

there are 2 solutions.

first, lets have some definitions of commonly used adjectives, and post them where all can see them.
this may not be practical, so hear is solution 2:

describe the sound, instead of saying bright, say elevation in sound pressure in the range 1000 hz to 3000 hz. that is clear and specific.

if someone is looking for a cable wwith a particular sound, describe the sound specificalyy instead of using adjectives.

the word "polite" has idiosyncratic conotations. say what you mean by polite instead of saying "polite".

there still is an unavidable problem, namely differences in perception. someone may hear an elevation in spl in the bass (50 to 100 hz), while someone else may disagree, saying there is no increase in spl in that region.

differences in perception are unavoidable., but at least specifics make it easier to confirm or disconfirm a perception or opinion.

No, Mr. Tennis, it isn't that easy. You must, at the very least, find both a brass cymbal and a steel one, and listen to them over and over and over again until you can tell which is which without looking. Then and only then will you be qualified to judge whether a certain system makes cymbals sound more like brass or steel.

Listener training is not easy. If you want to get an idea of how hard it is, Sean Olive wrote an AES paper on training his expert listening panel at Harman. Not only were untrained listeners terrible at the task (in this case, identifying the general frequency region that was out of baance), but must people still couldn't do it after extensive training.

No audiophile or--more importantly--audio reviewer has ever subjected himself to that level of ear training, which is precisely why subjective reviewing is worthless, no matter how tightly you try to control the language they use. Your holy grail doesn't exist.
I agree with Pabelson, this is far from easy. 1000hz or 3000hz. Brass versus steel. Everyone must be able to discern these differences in an exact, uniform and unanimous fashion for them to have any meaning at all.

Besides, I don't have a problem at all with the various ways people describe what they hear using the existing terms or even a person's own unique writing style. I've been buying used equipment on Audiogon for almost six years based on other member's descriptions and have almost never been surprised.

Take for example the second post by Skyboy in this thread. WHo the hell else writes like this? Yet I made a purchase based on his post and got exactly what I expected:

MrTennis, I'm wondering if you had something like this in mind when you talk about steel versus brass sounding.

A few years ago I compared Acoustic Zen Hologram II speaker cables versus Audience's AU24 over a five month period. One of the descriptives I used when trying to relate the contrast in the way these cables rendered high hats was that with the AZ Hologram I was much more aware of the sizzle and shimmer after the strike, where as with the AU24 the sound of the wooden stick hitting the metal surface was more central to the sound.
hi gunbei, i think you're onto something. if you mean that the sound of the wood of the drum stick was more noticeable relative to the cymbal using the audience cable, relative to the acoustic zen, then i believe you have communicated clearly.

would you perhaps also mean that there was a difference in the balance, especially in the lower treble ?

the other comments about ear training are accurate and any anecdotal, subjective statements about the sound of steel vs brass should be taken in the context that a listener probably has not had sufficient training to make a definitive statement.

since most listeners and reviewers have not had rigorous training in the detection of instrumental timbral differences, subjective comments are at best taken lightly, like other subjective opinions.

unfortunately, making decisions based upon such comments can be risky.

That could well be true. There are at least two "Ear Training" courses available in CD format, by David-Lucas Burge*. I own them both but have been too undisciplined to go all the way thru them (my bad, but at least I'm honest).
