Title: Foamrite Acoustics Measurements Finally Done
Post by: stereosane on November 23, 2017, 11:23:46 AM
I see they finally did some measurements on three of there products, but none for there Bass traps.. I have a feeling the Measurements of those might hurt business  :giggle:

Anyway I see they have a new diffusor panel which looks nice, here are the Measurements, can anyone tell me by looking at this graph if it is actually doing what it's supposed to do, I'm keen to try 4 out on my ceiling in my small room, I'm hoping to add a bit more of a spacious feel to the room..but I'm not so clued up on what the graph should look like to indicate it's doing what they say it should..

But isn't a diffusor meant more for the higher & Mid frequencies only and not bass frequencies?

quite right and understanding how to the vertical scale should be interpreted is the key - maybe someone wiser can enlighten us
agreed on the bass trap issue

Whomever did those measurements is a laughing stock to any acoustician worth their salt. I get the impression that these were not done in a reverb chamber for starters and thus of no comparative use. If they are indeed somewhat reflective of product performance unfortunately they somewhat confirm what most suspected...very poor efficacy compared to conventional materials.
