sound absorbing materials

["Irene Vollmy" <>]

Dear all

We have a question concerning materials which absorb sound:
We are currently working on a project investigating the impact of
anthropogenic noise on fish behaviour. In order to test the impact of
noise in fish tanks, we are looking for waterproof non-toxic materials
which absorb sound to minimise sound reflections at tank walls. Does
anybody know of materials fulfilling these requirements?

Thank you very much for your help.
Kind regards,
