@brownsfan Thanks! As my dad likes to say, "Don't borrow trouble."
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

Early lateral reflections contribute to spaciousness and expand the "apparent source width", according to Floyd Toole. Which I agree with, but is subtly, different than what I am arguing about. :) I don't think the laser line matters so much as having the area in general treated. |
We think we know acoustic.... But acoustic is like other science full with unresolved mysteries.... I just read an article, an interesting one, where 3 specialists discuss without being able to be in total accordance about the basic acoustical treatment....And they are specialists.... https://www.acousticsciences.com/media/articles/room-acoustics-audios-final-frontier Myself how can i change my room acoustic with cheap metal buckets glued together with an array of different stones on them ? The stones making a difference in the reverberation time control.... Is there a set of linear differential equation to explain that? :) For reflections we can use them or neutralize them..... In a small listening room it is better to use them......In a control room it is better to neutralize them..... Myself i use them ....
