Regarding angled surfaces/panels... soundwaves are not lasers, despite so called ray tracing...even at higher frequencies they are conical, until we get down to very low frequencies which are spherical, therefore an angled surface still needs to be sufficiently larger than a given wave length in order to deflect it. For example, if you read the BBC Research and Development report 1995/4 on Controlled Image Design control rooms, you will read that a surface of at least 1m wide is required to sufficiently deflect frequencies of 1khz and up. That is a surface 3x larger than the sound waves in question.
It means, this is the same video I probably saw a few days back, right?-With the correct formula. I almost convinced myself that I time travelled and already saw this video days back!!!
I'm struggling to understand wavelength as a distance. Does it mean that in a specific distance, all the different air pressure levels of the wave are within?
Yes, more or less. It helps to visualize it as a 2d sine wave (a sort of cross section), the length being both phases of the wave (to where it starts to repeat).
@@gegilog7493 yeah I was asking about that :)) I thought of it afterwards (a lot :))) and the only explination I have is that he had some notes on his desk to read from and he did that to turn a page or something. But it's funny how it's edited there.
I’ve read Mass loaded vinyl will not dampen or block sound when place in paneled sections. MLV requires a airtight seal in order for it to effectively absorb/dampen sound waves. Correct me if I’m wrong
Quick question. If the walls of the room are not parallel, are absorbers still necessary? I just read a post in a Facebook Group that says they are not, because there will be no standing waves. If this is the case (I doubt it is) , would it not be easier to simply add paster boards (dry wall) in the room to make the wall angled, rather than make and hang panels? Thanks

This is the version with the correct formula - thanks for updating it Jesco (that's the _most_ German thing I've seen today).

@@grayveeacoustics It certainly appears to be that video, updated to correct the formula, yes.
_Or maybe it was a glitch in the Matrix..?_ :)

Wait, am I gonna wake up to Sonny and Cher again tomorrow?
You will have limitless possibilities of making the perfect comment.
so we gonna act there wasn’t any sus at 7:40
:)))) what was that?

I would advise much shorter videos, this one caused me rather more questions than answers and quite a lot of confusion
no! the more information the better!

You're right, that's untrue.
Essentially, all the typical challenges must still be addressed with non-parallel surfaces... it's just less predictable.
It's even more problematic.
