I find it very hard to believe ...

YRP, They may have knowledge of their equipment, but not knowledge of what frequency to listen for from an aircrafts acoustic beacon. That's not something they do everyday.
And yes, people are generally that stupid. They just front like they know what's going on. It's a natural defense mechanism.
As far as a reference, look it up yourself. You'll remember it longer. Believe me, if you do your own research, you'll find how competent/incompetent people, governments, businesses, etc really are!
Coagie makes a good point. If you are seriously interested in effective research I recommend learning a few quick-win effective research techniques so you don't have to bash fellow PPRuNers for their sources! E.g. start with Google and a few well chosen search words like
AF447 acoustic locator sonar frequency.
Then in seconds you might easily stumble over stuff like:
BEA to examine why acoustic sweep missed AF447 recorders - 5/5/2011 - Flight Global
