proximity effect has a wikipedia page:
https://en.wikipedia.org/wiki/Proximity_effect_(audio)
Thank you, schrm. I can't say I understand all of that, but I get the general idea.
(that's more or less the same with me :-) )
While deep he-man thundering bass might be effective for "power voice-over" use, it's not appropriate for Librivox, IMHO. Most of the information in speech is between 300Hz and 3000Hz (the so-called "telephone frequencies"). I have a 100Hz high-pass filter on my mic, which I leave switched on.

I mention this because you generally do want to get as close to the mic as possible to reduce the relative intensity of room echo/reverb (unless you have a really well treated sound booth), but getting really close (like a couple of inches away) probably results in booming bass unless you add some kind of filter (in the mic or in post).

I read the Wiki article. I wasn't greatly impressed with it - it didn't really explain why the proximity effect occurs.

well, you can edit it to rise the quality of the article?

in the german version, there are strict rules for editing. but i am not able to really compare the informations between the two versions..
i think you can use google translate to check it, though:
https://de.wikipedia.org/wiki/Nahbesprechungseffekt
en: lay down your arms, essays on art by goethe
de: sammlung prosa, hoffmann*2: sommerfrische, tante fritzchen
dpl: hoffmann*2

with doubtful joy, i am participating several times:
