Acoustics like oceanograpy, architectural acoustics

[chound]

I gave my name for a compteition (though in my right mind I wouldnt) where we have to present a 10page report on any part of acoustics like oceanograpy, architectural acoustics, etc. I don't know what topic to chose. I want to do on echolocation but will it be enought to fill 10 pagss of A4 sheets? Is there any other interesting latest topics?

Whole books have been written on this. You should be able to
muster 10 pages with a few dozen hours of reading beforehand.
