Thinking about putting these things in corners for sound aborbtion--
1. A surfboard. (Plastic shell but LOTS of foam inside)
2. Foam body boards--for having lake or ocean fun--Ive got 4 of em....
3. "Water Noodles", or "Water Weanie" floatation things, you use them in the pool or ocean. They are totally fluffy foam and soft.
It sounds a little wacked, ,,,well, frankly, ,,I'm a little wacked, but they've got foam, and I can stack them to achieve increasing thickness, especially the foam "water weiners" and wave body boards. I think that I could mimick a corner bass trap with the water noodles--heck I can make them triangular and they have irregular edges--and it cost pennies in comparison to the commercial absorbtion products. I can stack the foam body boards and get to 8 inches of foam! The other thing is that these water toys look wierd and ecclectic and not as sterile. I don't mind looking wierd. My room has not been swept yet--I'm just assuming that I'll have some low frequency absorbtion issues which should be addressed. Give these water toys a try?
Have a good one--and best regards in your studio.
