I dont think it has any major effect on the sound/acoustics of the room. Its a very thin fabric. Ive talked to many guys who have done triple black velvet treatment in their rooms and none of them have said the sound suffered or any major change they have seen in terms of acoustics.Black velvet changes the sound(mostly in a good way)
Now Triple Black velvet is a brand name,actually. If the composition of the fabric is known it would be very easy to find out what kind of Velvet is actually used.
