pumps

Bought a cheap $$ LP pump by Coral Life; the only thing that might pollute more the noise environment in my tanks is an F-14. Any suggestions on how to muffle the output air so the fish can have some peace and quiet?? Of course this begs a stupid question: Do fish have "ears" and even care...
