Yes, that is actually a good topic; inverse laws, far-field vs near-field "stuff". Thanks.Yikes. Some Gefell measurement mics had flipped polarity for years and that has created a lot of confusion. It became standard procedure for me to test mic chain polarity by popping a ballon (my breakfast paper bag ;-)
As for misconceptions, a very annoying one is the "inverse square law" for sound pressure vs. distance, when it's actually only 1/r. Even renowned text books have this wrong, confusing pressure with intensity.
And for resources, the website of Eberhard Sengpiel (RIP) is a classic -- really a jewel -- with very accurate and condensed info without bloating math. It's main focus is on recording techniques and microphones but of course much of this also directly transfers to speakers.
Best entry point for non-german readers is via the google search presets: http://www.sengpielaudio.com/Searchengine.htm
Also there are many online calculators: http://www.sengpielaudio.com/Calculations03.htm
Also, https://www.acs.psu.edu/drussell/demos.html is a good resource.
And Erin and I will probably do a video soon on Beaming/Radiation from a source.
