OH! you wanted audio definition

realism,,,, or one of those thingys the nascar boys use to change tires

The proper leading edge of a note or sound. The transition should be fast but controlled. Volume is not the measure since very subtle and/or quiet sounds can have definite "impact".

The good Dr. has the key about the leading edge of a note or signal:

Using a single square-wave input cycle (okay, it's clipping but I'm using Paint and it's tough doing a sine wave cycle in Paint)


Good Impact

Fast response to the initial input. Grabs the input and sits on it.
Little slop on the top, almost no ringing.
Not as important, but fast decay with little overshoot on the bottom.
Sign of good materials, fat magnet, very lightweight but sturdy materials.
Good "Pop" regardless of level of input.

Bad Impact

Think 70's Magnavox stuff.
Crummy coil, magnet, heavy cone material causes a huge lag in getting this lump off the starting line. Poor materials may cause it to not even reach full travel on a normal strong input signal. On the loss of input, a lot of ringing from no braking (crummy coil/magnet/materials).
Instead of "Pop", you get "Mumph".

If you would just hook up the MITs I shipped you, you would have the answers to these questions.

Bass impact being felt by the body.Visceral impact.

Sound presentation from speakers being realistic. Soundstage imaging impact.

Interesting. Defining terms is of course, 'subjective', consensual and historical. Look at any dictionary over the years. Usages change, some words pass away, neologisms are born, and compilers have to collect things like frequency of occurrence, etc.

When one reads reviews there is also a certain amount of creativity involved. Certain reviewers have a greater descriptive facility than others. And some are just pretentious--using affected language so as to seem esoteric and erudite!

I suppose asking people what they think a term means is a good exercise in trying to tease out the possible parameters of meaning and experience.

The problem I have is that with "impact" the only understanding that I have of such a term as used in the Audio world comes DIRECTLY from 'reviewers' and not from my personal experience so I really couldn't say what I think it means--I've been conditioned by those I've 'read' and some were reasonable and others were, let's say, inventing and embellishing.

Well damn, I can not argue with that. Probably the best definition so far but as you know, I'm looking for the audio side of things.

Review forthcoming. I think you will be surprised at the results. Until then, my lips are sealed.
