Our own Mike Rivers posted a link below and it blows the article that I started this thread with out of the water.
A bit longer read but well worth it.

I also found this blog post interesting, although in context it is a bit fluffy. . First a disclaimer - I have no affiliation with Izotope, I have some of their products and like them and yes, I always wait for things to go on sale before purchasing but I pay the asking price and do not receive anything free unless it is a universal gift to all.

A history of the decibel and why it is useful.

Too much "beyond the scope of this article" in that article. It's really not rocket science.

I have affiliation with Mike Rivers. See Meter Madness from my web page.

Yeah, a good editor could have shortened that article considerably without compromising information. Will click on your link next, thanks!!!

Thanks, Sir Mike, that was quite a read but a fantastic overall presentation. I learned a few things, mind you I am sure you've forgotten far more than I will ever know.
Kudos, I am going to edtit my first post to include your link on top. Cheers, Kuru

That was from when I was writing for Recording Magazine monthly, and when they'd publish longer than one page articles. I got paid for writing then. Now I have to find fun things to write about because nobody will pay me any more. It's getting harder to get manufacturers to lend me stuff for my deep dive reviews because the only place I can put them is on my web page, and on a busy day, I get about 10 visitors. They want at least 1000 eybeballs (well, 2000 eyeballs) a month before they figure enough people will read it to be worthwhile.

I'm an EE and dB is a vital component of my work.

Yes, as noted in the OP, I put Mike Rivers excellent article at the top of the page and left the Izotope article for further ponderance since it does broach on an interesting topic.
Thanks for including correct information, it increases the validity of the thread considerably!
