Test Equipment vs The Ear


Just posted this link in another thread,

Could the ear actually be superior to test equipment?

What do you think?

@eoffkait - I immediately thought sound-stage (or image) also - but the others you mention are equally immeasurable - except perhaps for dynamics?

At present, dynamics can be observed on an oscilloscope and if plotted against X-Y coordinates and factor in time, one could come up with some sort of measurement - e.g. slope/micro-second perhaps?

If anyone out there is aware of a measurement for dynamic performance I’d love to hear/read about it - thanks :-)

But I still ask - why bother - when the ear is so much more convenient and adept at discerning so many sound quality "improvements"..

I think it’s just "human nature" to want to qualify everything as proof of superiority - especially when our hearing starts to fail us.

Like you - I trust my ears every time - I stopped reading specs back in the 80’s.

@shadorne - if you are referring to...

I do not believe any of those tests indicates the ability of a speaker to respond to a very dynamic transient signal - such as a drum strike.

They would need to record the transient response i.e. the slew rate and rise time of such transients

It is something the ear can discern very easily and something you can see on an oscilloscope, but to my knowledge (which has its limitations) I do not know of any such measurement reported specifically for speakers at present.

From Wikipedia...
Transient response
.... In loudspeakers, transient response performance is affected by the mass and resonances of drivers and enclosures and by group delay and phase delay introduced by crossover filtering or inadequate time alignment of the loudspeaker’s drivers. Most loudspeakers generate significant amounts of transient distortion, though some designs are less prone to this (e.g. electrostatic loudspeakers, plasma arc tweeters, ribbon tweeters and horn enclosures with multiple entry points).

As for the tests above
- I do appreciate the value of such tests if a person does not have resources (i.e. good audio stores) for audition purposes
- Personally, I have been fortunate in the past to have access to some very good stores that allowed me to audition their very high end products. which has helped me in choosing the components i now own.
..
Mostly, I value the opinions of forum members - but ultimately I trust my ears.

Cheers
