Very interesting distinction i never even thought about...
Thanks for putting it ghdprentice...
"Wall of sound" is for me the definition of hell...
Holography is heaven... 🤓
The main difference is the decibels level and in one case silence and relaxing sound at normal ; in the other case body rape loudness and agression with premature tinnitus and deafness... For sure i put it in an extreme way but....
Rock concert are not designed acoustically as small music concert hall ...
Did i understand well ?
The concept of "wall of sound" was created by Phil Spector...
It sold a lot of tickets and impairment hearing aids 30 years later......😁😊
But true holography may engulf the listener in sound too with sound sources near him or behind the speakers or around the listener... It is recording dependant... But not with intense dynamic and over the board bass pressure rushing to the listener from the speakers in front of him...
But true holography in a small room is very difficult to create...With headphone it is very difficult too because no crosstalk and there is not acoustical control of the shell in most headphones..
One of the most incredible system I have ever heard was a Wilson Bamm or Wham or something like that / Rowland. The system was set up perfectly. Images were precise and sounded spherical suspended in the sound stage… one 12’ forward 3’ above the floor at 10 o’clock, another 5’ above the floor and 6’ at 2 o’clock… like that. It was the most incredible experience I ever had. I came away just blown away, saying… “That is the most incredible thing I have ever heard… I do not want that… but that is incredible.
So, yes.
Some folks want to be engulfed in sound… enfolded, or have a wall wash over them. Holographic imaging does not do that to them. So, yes again. You’ll see some dynamic speakers system six feet high with tons of midrange and woofers. Typically those are designed for more of a wall of sound and less for holographic sound.
