    Just try it. You are not going to do any damage!

    The more hydrophones floating about the better (See my other post today!)

    Piezo elements are fairly "high impedance" but a lot of reasonably sensitive audio amplifiers will do the trick.

    The sort of sensitivity you are looking for (with the hydrophone element on a table) lightly tapping or scraping the table should give a noise over the headphones. (Headphones are always better, for some reason.)
