Room Treaments - Where To Begin...

I am an engineer with experience in acoustics, though mostly in the field of explosives (don't ask or ----).  Equalizers or DSP do not solve your room problems, altering your room solves or helps with your room problems. The first question is what is the problem.  In my current room it was a massive bass problem, in the end I built 2 very large bass traps (1.5 x 0.8 x 0.8 m). These help enormously, any smaller made little difference.  I also use 2 subwoofers which help with balance. 

  Now wouldn't that be a cool job and quite a challenge. "What? I didn't hear anything."

Recently, I found this PDF available for free download. There are newer editions available.

THE MASTER HANDBOOK OF ACOUSTICS 4th Edition by F. Alton Everest

That is a serious book. Good Lord. 10 pages of table of content.

My hole booklet about acoustics was 10 pages long, WITH a table of content and one "this page is intended to be blank".

That guy had something to say.. :-)

Don't judge a book by its cover. The cover says, "Acoustics hard. Use headphones."
