Water Absorbers
« on: September 13, 2006, 05:11:51 am »

Dear Fran!

Since water is another element you like to live in, I have a mayby totally silly question that nobody I asked before could answer.

What happens acoustically if you pack water in a foil (like those used for artificial ponds in gardens). I think water has no special resonance but relatively high weight. It will be moved because of its flexibility and therefore absorb/transform some energy. You can shape the foil in any way and if you drain off the water transportation is easy.

Do you see any sense in this?

Please excuse if this is crazy.

IIRC water has an extremely low absorption coefficient over the
interesting frequency range.
Adding bubbles to the water would help for higher frequencies but
how would you keep the bubbles in there for a longer time?

yeah... as us Scuba diver know.. water is actually a much better conductor or sound, because of density, than air. Probably not a good absorber OR transmission loss material.
