In a modern society
Engineers must be licensed and that requires demonstrated academic achievement. Passing comments here has no such requirement, but that does not preclude educating yourself on the topic at hand. That is exactly what is happening here and I have provided copies of some important papers on the subject to help out. When some one poo-poos the educational process I will raise an objection to that notion for obvious reasons.

Ive worked as an engineer for a number of years. many of them leading the engineers in throughout design process and often as lead vision in design or at the least helping them to understand what the customer really wants or needs and working with them through their own design process. Most of my work has been within the scientific community
(both academic and non) specifically in the area of designing equipment used in Syncrotron facilities. Traveled to evry corner of the globe in this capacity, hold three patents(two of them actually worth something
, and after playing the fool even talking this way heres the punchline....
I do not have a formal engineering degree
I can tell you from experience, that no mater your past experience/accomplishments, in some academic circles, if you dont have a degree you will get no respect. And if in practice if you show them up, especially by finding simpler and more practical ways to accomplish somthing, look out. Your days are numbered.

Degrees by themselves don't matter, learning and developing competency are what matter the most. That being said, most people do not undertake to learn certain very important aspects of what they will need to know in an area like engineering by themselves. A few do, however. Of those that do, a few of them get pretty good. It may not be the easiest route though. Have to learn enough math and physics to understand a lot of the engineering literature. Not very many do it on their own.
Degrees do not guarantee competence, but they are recognition of some minimum level of capability (at least at some point in time.) It is certainly possible to learn anything on your own, I have done that many times. I have never had a class in DSP and yet I know it pretty well. But, on average, it is unlikely that someone without a degree will be as competent as someone with one.
As to the question about non-linearity affect the frequency response, the answer IS yes and no. If the transfer characteristic of the system is expanded in a series then several properties emerge. The odd orders are couple and the even orders are couple, but there is no coupling between them. All orders affect lower orders. So even orders will affect, for example the dc offset, while odd orders will affect the linear frequency response. But remember that we are talking about small %s here so the effect is never large.

The mechanical point of symmetry may not be the same as the BL symmetry point. Acoustically you will see nothing in the measurement, so from a room and recording point of view, it probably means nothing to you. I do believe Klippel has a video that demonstrates how this happens. Perhaps you can look through their download section.

1) I agree, the educational process never ends. That requires reading published texts on whatever subject you pursue.
2) Without the degree(s), there are a lot of opportunities that simply pass you by. And, I am sure you know that fact very well.
3) Not every one that gets a degree, is an honor student, and not ever one that fails, is incompetent, but we no where the recruiters look for the new hires.
4) Hey Earl, your second paragraph is not understood here as well. And it conveys notions a lot more sophisticated than what I am willing to present here. Even if you yell in a windstorm, you will not be heard from very far away.
5) I do not post on this forum much anymore, because I find it a waste of valuable time.

I write for those who want to learn, not those who believe they know it all already. If my writing is over someones head then that should tell them something. If I had to lower my discussions to the lowest common denominator, then I wouldn't post here very often either. If a few get the point, then I am willing to leave the other 98% behind.
Surprisingly, it has been proven that sound travels farther upwind than it does downwind. So much for intuition

A problem for me is that there are good intelligent people that are not technically inclined.

Counter not only to intuition, but observation as well as per page 292 here, those surrounding, and other instances in the book. I am really curious about the newer research on this that you seem to have read as I'd just like to know the mechanism of it. Something other than the wind gradient in effect deflecting upwind sounds upwards and downwind sounds downwards, I presume?
