Is it not easy for one who might be sceptical about room acoustics to take a different approach and use common materials, like household goods to some cheap fabrics? Then make his and hers own treatment within less than £$100.00 pounds/dollars?
I was looking at the different shapes from plastic ready-meal microwave meals to Pringles for diffusers and even pillows as some type of absorbent or other?
There are so many cheap items out there that one might not even consider fabricating into practical acoustic device rather spending enormous amounts of money on few tiny overpriced products.
Picture of the front corner kitchen shows some items I’m considering using. I buy enough of the ready-meals each month I might as well stack up a few hundred and make them into a diffuser of sort?
Clean them up obviously and spray paint them a different colour.
Any thoughts on this and yes laugh away if you want because I can turn the other cheek as well.
