Does the first reflection point actually matter??


Hello my friends,

So please read the whole post before commenting. The question is nuanced.

First, as you probably know I’m a huge fan of the well treated room, and a fan boy of GIK acoustics as a result, so what I am _not_ arguing is against proper room treatment. I remember many years ago, perhaps in Audio magazine (dating myself?) the concept of treating the first reflection points came up, and it seems really logical, and quickly adopted. Mirrors, flashlights and lasers and paying the neighbor’s kid (because we don’t have real friends) to come and hold them while marking the wall became common.

However!! In my experience, I have not actually been able to tell the difference between panels on and off that first reflection point. Of course, I can hear the difference between panels and not, but after all these years, I want to ask if any of you personally know that the first reflection point really matters more than other similar locations. Were we scammed? By knowing I mean, did you experiment? Did you find it the night and day difference that was uttered, or was it a subtle thing, and if those panels were moved 6" off, would you hear it?


Best,


Erik

Funny....Yarlung states their generator fits a 2U rack space.

Which is just about the size of the Carver units.....🤔

...and I've got room for 2 of them....;)

...some will say I'm 'spaced' enough already....*LOL*

We exist in a universe of waves...beginning with the subatomic, density and type variants all....

It just 'thins out' the further off we rise from what we percieve as solid ground.

And we're just another version of it, making waves of our own.

J'accuse:  The number of things agreed upon = the number not.
The universe is subject to the Bell Curve as much as we 'average out' in our HO about what we hear, how we hear it, and how we feel (or don't) about it ....

Flies in the fluxes of universal ambers...in the midst of all the other waves...the daily surf...

Not terribly sci about it, but it makes for my day. *S*

One can also apply that concept to tuning ones' listening area.  It's possible to correct Everything....but you couldn't live in it.

But your significant other will demand that you do...Now.

Erics' 'mountain range concept' has appeal; the space 'gets out of the way' of the audible 'view'.  I like that...+1, at least... ;)
@gs5556 ....the Yarlung site was a fun listen with my diy Walsh, which already project a large soundstage by themselves. *S*

'Sonic holography' took me back to when I owned a Carver C9 Sonic Holography Generator back in the '80s'....It didn't work consistently with everything; whether this was due to the mixing, the format, my space and placement within....

....but, when it did....you almost felt you could grab the neck of the lead guitar...;)

1st reflection with omnis (or, for that matter, dipoles) becomes either a moot point or the 'sticky wicket'.  When 'all', or nearly, becomes reflection the room becomes part of your 'system'.  It can't be ignored.

My current space is so ghastly that all I can do is to reference the late Linkwitz and 'ignore the room'.  This consists of running 5.1; F & R, L & R, with a sub 'up front'.  Works best with 4 identical drivers in the corners....

I can add a slight delay to the back pair which can enhance, but it becomes 'selection dependent' and a PIA to do. *L*

But then I'm 'listening to the stuff' rather than 'listening to the music', which kinda defeats the goal of it all....and I'm pretty atypical in approach, anyway....

Best, J

As a fanboy of active room eq and the means to accomplish such...

A pair of ears, however compromised and even biased, can hear and discern 'details' that a calibrated mic with it's software may only hint at, or 'gloss over'.

Mho, one would need to be running some rather sophisticated wares, running in r/t into a 3D waveform to catch 'reflections'...and, even then. they'd likely be effected by frequency, harmonics...and even ones' presence in the space....

...and be very persistent and equally patient in the measurement routine.

I am an imperfect being in an imperfect world, surrounded by imperfect 'things' playing imperfect sounds.

Eventually.....one has to accept ones' limitations...

(Thanks a whole bunch, Harry....*smirk*)
