I have this general suggestion for those wanting to learn about acoustics:
A) read this Acoustics/Treatment Reference Guide
, via gearslutz, its a easy read in layman terms, starts you off with basics and good foundation with practical discussion. Studio acoustics and Home Theater acoustics.
From that, simple/straight forward advice via Jens Eklund:
1. Learn how to make measurements: REW - Room EQ Wizard Home Page
Don't do anything without measurements.
2. Define your MLP (Master listening position). Confirm with measurements.
(Mike R modified for HT viewpoint)
3. Identify and treat your modal and SBIR - Speaker Boundary Interference Response
related issues and educate yourself about different bass-absorbing techniques.
Other info: SBIR by Bryan Pape
4. Treat areas that otherwise creates early reflections.
5. If the room is big enough, add diffusers (but read up on how to use diffusers before going nuts).
Always base your decisions regarding different treatment, on measurements. Avoid thin porous only absorbers (including wall to wall -carpet, drapes etc.) unless a measurement indicates the need for it.
B) Knowing that for best audio/sound in a listening room, these parameters are tackled in prioritized order:
1. Speaker location, 2. Listener position, 3. Acoustic treatments, 4. Electronic correction.
Understand the small room acoustic model you will follow.
Looking at this link, everyone can see visually the various small room models, it's 7 pages from the book "Acoustics and Psychoacoustics Applied"http://eetimes.com/design/audio-desi...n?pageNumber=0
C) Then I'd say read the first 4-5 pages of Acoustical Treatments Master Thread
, there are 200+ pages there but first 4-5 cover much of the stuff
D) Then, post into link given in C your room size/etc and ask your Q's there, if not already answered by doing A), B), and C) above
E) If you have desire for more knowledge:
-read one of many books out there, a great 1st book is "Master Handbook of Acoustics" by F. Alton Everest, a perfect follow-up book is "Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms" by Floyd Toole.
-study Ethan Winers site, http://www.ethanwiner.com/acoustics.html
-Become familiar with the different small room acoustic models for home listening spaces
-This is also a 101 read on Room Acoustics, http://www.crutchfield.com/learn/learningcenter/home/speakers_roomacoustics.html
-SAE Home Acoustics info site has many definitions and explanations http://www.sae.edu/reference_material/audio/pages/fullindex.htm
-There are many other sites on the web, like
........One of the first ones, StudioTips small room acoustics forum http://forum.studiotips.com/index.php
........Acoustical measurements defined Rives audio http://www.positive-feedback.com/Issue12/rives2.htm
........RPG Acoustics Library papers http://www.rpginc.com/news/library.htm
-Be careful of info overload all at once
F) Measurement info/threads:
-Get the hardware side of REW down quickly, this thread by member omegaslast dummy's guide on setting up REW
and his blog http://polaraudio.blogspot.com/2012/01/calibration.html
easy 101 read with pictures to walk you thru the mechanical of set-up and taking measurements
-Highly recommend Nyal Mellor's site, http://www.acousticfrontiers.com/Aco...surements.html
, and a very detailed/helpful white paper http://blog.acousticfrontiers.com/st...ist.%20Rms.pdf
