Just made my first anechoic chamber! :D

Man that was terrible work, I used about 5 square metres of molitan (local business name of PUR foam) and couple more of acoustic wavelet to cover the sides from inside. That cheap sound meter toy of mine shows 38.7 dB in silent room. Better than nothing I guess. I'll go to try the first PSU inside. If all goes well, I should also be able to measure PC cases there, though it won't be as good as it should be - there is not THAT much of space inside so it'll be about 20 cm only from the front of the cases to the meter. And don't tell me anything, the chamber is already huge as it is, designing it for the biggest cases on the market would be terrible. This old carton box from our 1990s Finlux TV set was the biggest thing I found anyway
I don't aspire for any real sound measurement for the moment, more like comparison between different HW. But for a start, lets at least do it wannabe properly, not just sticking the meter somewhere around the device in ordinary noisy room, right?
