decoenthusiaste You need more fabrics to absorb it. replacing leather with fabric will help too, as will larger area rugs, lots of pillows and throws.

ASVInteriors Tech solution: It seems your high ceilings are bouncing the sound upwards. So you need to dampen the sound. The best solution would be to hang fabric covered panels on your walls to absorb sound waves. I have seen this done with thai/shot silk. However this may not be in keeping with your look. Tapestry? Failing that can you thicken your curtains with a heavy fabric such as velvet or another sound absorbing texture?

Note decoenthusiaste's pictures feature tall curtains that help absorb sound.

loroca If its possible with your budget, would you consider beams? That would absorb some sound.
