My room in new flat has got pretty bad acoustic, huge windows height ceilings and brick walls. How to resolve it?
In the beginning I have had two major ingredients:
– old picture frame from Ikea
– acoustic Rockwool 60gsm 60x120cm 10cm thickness
Sound absorption panels trap acoustical energy (sound) and prevent it from reflecting off of the surfaces they cover. The panels are used to eliminate echoes and reflections that muddle or color amplified music and speech. These wall panels will also reduce reverberation levels in a room, which can sometimes provide ambient noise reduction.
– Rockwool absorption panel
– MDF or wooden boards
– Decorative fabric Japanese Zakka French Chic Newspaper Cotton Linen Fabric

Idea behind is to make nice looking acoustic panel which don’t really look like acoustic panels. Have I succeed? Take a look:
Ikea picture frame. Take it apart and remove poster and acrylic glass.
Actual fabric. 70% Polyester 30% Cotton
Glue fabric to the paper
Let it dry stretched
Measuring for frame.
Frame screwed and glued together. Then glue it to paper and picture frame.
Cutting mineral wool with bakery knife. This material is a bitch.
It’s itching everywhere, even when I used gloves. My trousers were sparkling like that vampire guy from Twilight saga :)
Rockwool inside, dimensions are 100x70x12 cm with 2cm gap at the rear. It should increase frequency response in low frequencies
Rear side with string.
All done! Let it dry out over night.
Ready for instalation.
Picture frame is improving sound imaging and clarity for music and reducing slap-back echo and reverberation.
