Thanks for posting this article, Caio!
I have only one question: are you planning to update the list? I have found so many useful instruments while I was doing some research for my students. It would be nice to see them reviewed by your team.

A have only one addition to Matt's comment - keep in mind that blankets and foam mattresses (I used them back in the past when I had to fix the sound in an old wooden cabin we used for studio) are not the same as acoustic foam. Acoustic foams have more regular cell structure and higher air flow resistance, and therefore better acoustical absorption.

I'd be glad to join your meet-ups, Jay.

Same problem here. Should we wait for a moderator to figure this out?

My all-time favorite war movie is "Lawrence of Arabia". It's not entirely historically accurate, but it is visually stunning.
