Bass Nulls - Mix Position - or - Room Dimesions or ?

Are you really saying you can't see that there are two paths, each contributing different distances and thus different delays?

Asked and answered. If you still don't get it, I cannot help you.

Some definitions are open for interpretation, as my recent poll over at alt.sci.physics.acoustics made clear. You insisted that standing waves and modes are the exact same thing, but at least one pro acoustician at that group said my distinction has merit. Dr. Matt Nobile at IBM also agrees with my distinction, as did every other respondant in that poll beside you and Eric.

Off topic.

But to not recognize multiple interference paths amazes me. Or maybe you do recognize it, but disagreeing with me is so entertaining you can't resist?

Ethan, Don't disgrace my name. I assume you mean one of your traditional word games you referred to in the science group? Where you started out saying nothing, vague as always, hardly knowing yourself what you were saying, then confirmed what others assumed you were saying, thereby contradicting what you always were saying? Then further contradicted yourself, by confirming something else? And then confirmed someone else without knowing what the plain wave is he referred too? You mean that thread? The thread were you took no clearly expressed point of view, just picked out what you can use as confirmation of what you didn't express? I told you once before. I'm always staggered how you can twist everything, even plain lie, and still believe yourself. You pick the know-how of others, act as if it is yours, even when not understanding what you're saying, and start explaining the world via articles, as an expert with decades of experience. There was NO reason to refer to me in this thread at all, so don't. And your response now again is a smoke screen to hide that you don't understand what Jeff is saying (nor what you're saying yourself). Eric

Folks, 1. Ethan asserts that standing waves and modes are not the same thing. Here's a quote from the alt.sci.physics.acoustics referred to above:

Ethan Winer wrote:

To me, a standing wave is a pattern of nodes and anti-nodes caused by a wave bouncing off a room boundary and interfering with waves still emanating from the sound source, and with other reflected waves.

2. Ethan also asserts that modes are a subset of SBIR. 3. Take Ethan's definition of standing waves from the above quote and of SBIR from this thread and it should be fair to conclude that Ethan believes SBIR to be a phenomenon caused by standing wave behavior. So: Standing waves are not modes, but SBIR is caused by standing waves and does actually include modes as a subset. Interesting. Seriously, folks, if you want the skinny on modes and SBIR and the rest, I would recommend Everest's MHoA. There are other resources cited elsewhere, but this one should provide the clearest (read: least mathematical) explanations. Best regards, Jeff D.
