Hy… It’s been quite a while but being away
from all the chaos is a good way to spend the summer
well… not ALL the chaos.
Because I am crazy about music and audio stuff I finished my listening room this summer. It’s a 6x5x2.8 meter room dedicated 100% to my hi-fi passion. . . And this type of room needs a bit more than a sofa and a set of speakers – well, initially that’s all I had in it but the sound was just unbearable.
So…after a little talk to an acoustics specialist and a bunch of books and articles read I drew up some specs for what was needed:
- sound absorbers on front, side and rear wall.
- sound diffusers and dispersers.
- a few bass traps for testing.
The problem with all these is only one: price! very very very high price. So the cheapest way is to go DIY. . .
the absorbers were made from acoustic sponge and the synthetic fiber is added to liniarize the response at higher frequencies. There is a 5 cm airgap behind the lateral and 10cm gap behind the front ones.
The difference they make in sound is more than 100% – My speakers are a diy high-end project and I know how they should sound. well, at first I thought there was something missing mid-range disconnected or similar, unbearable sound. After the treatment and some minor tweaks everything was back to normal and the sound is almost perfect.
I still have to add some absorbers on the ceiling but this only come next Wednesday so pictures then.
