Come up with a new line.
HE is designing a LIVE ROOM. Newsflash! There is more to acoustics than simply eliminating reflections. And more to reflections than simply flutter echo!
Your one trick pony mantra of 'try a bunch of stuff' and 'use more absorption' and if in doubt, 'use more absorption' to create a dead room has grown old. The more mature world of acoustics has moved beyond this.
But you just can't stand or tolerate anyone making a suggestion for a PROVEN alternative approach, can you?
And flutter echo is perhaps the simplest issue in a room to resolve. And ironically EVERY suggestion made in this thread will treat it! But despite that it is perhaps the only reflective issue of which you are aware, which renders it a crisis in every case about which you post, that hardly makes it a critical issue - nor one that requires absorption to be used in your 1 trick pony solution!
Besides, can you produce tests utilizing the
precise type of absorption in the precise pattern to be used that will specifically reduce vertical floor to ceiling flutter echo for boundaries placed precisely 15 feet apart? If not, all suggestions of such are questionable. After all, the general use of basic fundamental units arranged in predictable patterns is
not sufficient, as you have repeatedly informed us regarding other Basic tools.
And as far as "return(ing) to the usual ignorant and vituperative form." Only you embody this repeatedly in your tired returning role as a fly offering nothing - as you express your derision and mistrust based upon an ignorance of proven designs - just as you have indirectly challenged their widespread objectively verified use for over 20 years by Russ Berger - someone, according to your esoteric standards, apparently well known for questionable designs and even more questionable measurements (sic!!!!) The irony is that perhaps no one in the industry uses the exact measurements you deride more thoroughly and consistently in their associated designs - as ANYONE even vaguely familiar with his history should know!
But then, listening to you, one should refrain from using 2x4's in the building of a projects, as you will not see "test data" verifying that a 2x4 can be used in every possible combination or permutation, let alone a screw driver used in the building of such projects!!! But then, anyone
familiar with the basic characteristics of a 2x4 (or a screwdriver) should feel fine proceeding within the parameters of the basic 2x4. And whatever you do, DON'T use a screwdriver to pry open the lid of a can! After all, have you ever seen conclusive tests verifying that such action can be effective or safe????? Oh the horror! But you see, the REAL problem is that dd does not understand how or why they work!
Take some of the time that you use to deride concepts that you obviously do not understand, and do a bit of familiarization with collimating phase gratings that have been well understood for several centuries. And they can be used in more ways than your overly reductionist use of augmenting ABSORPTION. And you only begrudgingly accept that, not because you have a clue as to why they work, but because the word "absorption" is used!!!
So let's review: ETC measurements - what they represent and how to interpret them, the Analytic upon which they are based, collimating phase gratings....the list grows longer...so many things that are prohibitively confusing to you - or, as you have stated, that should be left to only "pros" - which ironically explains allot!...
And please state the obvious correctly. I ONLY laugh at YOU.
