YOU CAN Be Sure About the changes in air pressure

Hi Tubeguy

Glad your feeling better!

Good question, what can you trust?.
This is a weird area, no lives are at stake, no large money involved, no accountability, no pressure for much of anything except “what sounds good”.
This direction is set in an area which hinges on human perception and so it is also more than just the pressure variations at your eardrums.
Lastly there are many aspects of hearing acuity which remain to be researched or are fuzzy so in some cases there aren’t any answers. Sound in general was considered to be sort of a dark art once.

What I think is interesting is the difference between the view of things in the sound mastering / engineering area where these guys are fanatical on listening to everything and hifi.
Some of these recording guys really are golden ears (from a billion hours experience), one fellow I knew set crossover, eq and time delay for a subwoofer / system by tapping on a sm-57 and fiddling.
I went back with a TEF machine later and measured and while it wasn’t perfect, it was pretty close (a stunning accomplishment).

Anyway, one real difference between the direction of “what sounds good” in home hifi and sound production engineering is the marketing of the products involved.

In one case you have people who’s pride of work and occupation / reputation is based on there sound quality (that others hear) and in the other, you dealing with companies selling to people with disposable income, where any extra spin or even lying helps sell product.
In recording, engineers are fully aware of hearing foibles and often double check so products like the pebbles, magic wood blocks, stupidly expensive cable etc would never fly as you can’t generally hear that kind of stuff if you double check (A vs B with no prior knowledge).
The true blue audiophile with a fully implanted hook would chime in “yeah, recording engineers, look at today’s music, look at the CD ugh”
Best,
