room acoustics

This is a project I've wanted to do for a while. I just ordered some wood and insulation for delivery from Home Depot here in the USA to make 8 acoustic panels, each 23" x 47.5" x 3 5/8" (~60 cm x 120 cm x 8.8cm) It turns out that making eight panels is a sensible and economical number of...

Hey guys, was advised by a friend to post on here. My setup comprises of: 2x KEF R900 1x KEF R600c 2x KEF CI160QR 2x KEF CI4100QL 1x Denon AVR-X6300H A year ago I moved into a new house and I just can't get the system to sound as good as it used to, particularly when listening to music. Due to...

This is a second part of a post about the construction of our listening room, this time concerning acoustic adjustments. The goal: the best possible listening space. Basic Properties of the Room A quiet place, far from low frequency vibrations caused by cars, trucks, trams, etc. The room is...

This is an account of the process and the steps we took when building our listening room last year. This part deals with preparations, plans and the construction, while the second part will deal with acoustic tuning and include more theory+advice+measurements. The goal: the best possible...

Moved studio monitors from corners to ~30% the length of the side walls closer. They are near the sidewalls, per Genelec recommending keeping them closer, or if there is space making sure they are more than 1.1 meters from the wall. this follows the first rule for the side walls, and the second...

Hello, A few weeks ago I got exciting news - we are getting a new house! (yes it is just like getting one more kid, in many ways) So what does an engineer-audioholic does in such case? Well, gets down to literature, measurements and guidelines to quickly design in a "perfect" listening space...

I'm about to embark on the design of HT in a house we're remodeling. I've got plenty of room for a decent size and design (at least 10x6x23, room within a room, etc.). Searching the net, there's lots of sites that assert that the Golden Trapagon is the preferred shape. Few of these sites are...

Hello everyone, I am new to music production and I want to arrange a room for music production. In this way, where should the speakers stand in a room and how can I make an acoustic isolation. Thanks for your time !

Thanks for reading this - I hope some experienced members can help me. Yes, I love the journey of measuring, listening, changing, and repeating again. However I have just spent 3 months tuning the speaker location and DSP/ DIRAC in my old apartment only to be moving to a new one! First world...

Hello, I want to discuss here the differences of wide and narrow directivity of very good speakers in context with room acoustics and more. One perfect speaker for all rooms. I don't think so. On conclusion of the research at of @Floyd Toole and others are that a good speaker sounds good in...

http://www.aes.org/tmpFiles/elib/20170305/18547.pdf This open access paper appeared in the most recent AES journal. Delay time and decay times were tested using various genres and musical tempos (bpm). The theory is that longer delay and decay times are better suited to slower music and shorter...

This is a post I made elsewhere to provide a high-level but detailed overview of how to look at room acoustics. It is the heart of the bible I follow. Hope you find it useful. ---- At high level, the key thing that unlocked this mystery for me, and hopefully will do for you, is to understand...
