microperforated glass

microperforated glass

(OP)
Hi,

I've got a project that consist in glazing the interior court back an old building. the ting is about 30m long, 20 wide and 6 stories high. Without treatment, the reverberation will be around 10 horrible seconds according to my calculation. i can place som absorbent under the mezzanines but the RT will still be too long (2,5s-3s). The architect isn't in love with baffels, the city wants to preserve the look of the old fasade, no panels on the walls is allowed then, I scratch my head to find a solution. I've already heard about microperforated glass with hole diameter of about 0,5mm with reasonnably good absorption qualities but I can't find any information about that product. Has someone heard or even already used that solution?

Thank in advance for the help,
OkdB

RE: microperforated glass

haven't used it, but you are going to be making a very nice Helmholtz resonator, at a rough guess. Should work well, if you can size the volume behind the glass appropriately.

Um, good luck! Do a lot of experiments.


Cheers
