BTW the http://www.mh-audio.nl/ site mentioned above is off-the-hook cool!
Michael, thanks for posting these links, I have learned a lot in a few hours. Things I thought I knew, and a few things that I hadn’t considered. Just from the link I quoted.
The task was to create one of the world’s best concert halls … It is unfortunately in German … but it is the journey
worth it … if you can get a ticket …
These guys are passing the house door. One of the tasks was that the ship’s horns etc. could not naturally be heard in the concert hall … Thanks Cunard Line for demo …
They often send live…so try signing up on their Facebook …
Hamburg’s concert hall is astounding.
i also relish the fact it cost $850,000,000. That is, a concert hall which rivals the cost of a new football stadium - money much better spent on art.
I love to look at things I can’t afford (at least if they are far enough above the budget)
Maybe some inspiration for @brodric‘s next investment
One of my good friends is good at building them lol 550 kg lol
I bought this App and - I’m sorry to say - can not recommend it.
I find the user interface and interaction design mediocre. The results are not very detailed and sometimes confusing.
My system rated “green” in all tests, which was to be expected, but I learned nothing more than that.
Thanks for the photos! Wow some interesting builds for sure!
Although I think the one with the bathtub (and the old guy in it) is a little bizarre.
apologies if it’s one of y’all
Those are my choice for diffusion. Yes, they’d be heavy but non-absorbent (if painted) compared to hollow plastic products, offers a quadratic variation of depth for the mathematically correct distribution in diffusion in both horizontal and vertical planes (versus those shown above), and an easy DIY project. Here’s a link for building them yourself:
