You missing the whole point. Acoustic reflection process is pure physics and implementation of it into the listening room setup, where the goal is full Spectrum music SQ (some time customised depends on genre or personal preference), is balanced process and not always dogmatic but compromised. Some flows of sound Spectrum you want to be reflected other not, that why all those room acoustic analysis services are silly. If you just try to break your sound flow with diffusers and rugged walls to as smallest particles you can, you wrong cause you will get nothing but dull woolly sound. Check it out how glass or sleek surface could be implemented-
@surfmuz First of all please post a link to your system and your room if you can.
In your video link a Russian guy sitting in a very small room with very low ceiling with huge speakers and some sick setup! Why did you post this?
My room acoustic analysis made by professionals, who are you to say it’s silly?
Each acoustic panel designed for work with certain range of frequencies and does not placed randomly, it’s not necessary to cover the whole room with panels everywhere to get dull sound, but there are absolutely necessary to cover first reflection points with acoustic panels, front and rear walls, ceiling also, the rest is more complicated.
For me it's no brainer to compare two rooms (one with bare walls, another with acoustic treatment).
This is a great channel to watch about acoustic treatment. So many different topics and everything explained very well.
Before someone chime in I want to say that digital processing in room acoustic should not be used with analog source (but can be used with digital source). Acoustic panels and room itself are the only methods for proper acoustic treatment with analog source (for us who listen to VINYL mastered in analog before digital was invented).
As I can see in
your other thread the question you asked about analog setup is a bit strange.
P.S. People who listen to digital should think twice before they post something for those who listen to a pure analog source only. Digital processing is death for analog signal.
