In my earlier post, I forgot the simplest mechanism of the ear: the eardrum. This is a very thin skin that vibrates with incoming sound waves. Its force is used to drive the middle ear's tiny bone levers, which pass the audio energy to the inner ear. So, accurately reproducing the eardrum's oscillations, should accurately reproduce sound, and the complex issue of understanding auditory perception down to details, would not be necessary.

Sorry for my aging-sluggish mind, but in my earlier post, I should have written this one instead.

Isn't the goal to as faithfully as possible reproduce the sound from the source, adding nothing, take away nothing? That is a straight-forward engineering problem.

May be, the most do misunderstand frequency response and THD as the goal;-)

And NOW you tell me?
You mean I WASTED my University time from 1969 to 1976?

Plus all the time expanding it until now?

You are making me feel very depressed, what a fruitless life

I think he also missed all those universities with audio departments. He just doesn't have a clue.

I have no quarrel with Control Theory itself, but when applied to the audio field, it loses validity becoming out of context, inappropriate, inadequate and misleading. It is also far too simple and superficial. Fortunately, there is a tremendous amount of relevant knowledge beyond the shallow Control Theory.

JMFahey,
there is always an impending danger of misunderstanding hanging over my arguments. Expanding each argument to the size of a chapter could reduce misunderstanding and improve clarity, but still no one would be convinced.

N101N, I guess you mean you are into the low-feedback or no-feedback camp? That can be traced back to a mistake in a 1966 article, see

Part of that also came from the fact that 'audio types' didn't really have a good understanding of the technical issues, so they were easily convinced that this was a real issue. It was also strongly supported by a lot of marketing, promoting amplifiers with wide OL bandwidth as 'better'.

People with enough engineering background would have seen through the shams but they were working outside of audio.

Marcel,
thanks for the hint. To be perfectly frank, I no longer read that genre of high-flying academic literature. The target audience seems to be people with solid engineering background, not unedified hillbillies like me.

JMFahey,
It`s not all in vain, but I would be extremely cautious about applying generic engineering principles to audio.

edbarx,
you can easily get exhaustive answers to those (off topic) questions elsewhere.

After 50 years of doing it, somewhat too late for that, but I guess I will survive

Yet that doesn't stop you from making strong, sweeping statements about the (in)eptitude of those with a solid engineering background.
