1. sometimes we use 'whoosh' for the effect of something very fast flying by you. 2. for falling into water, 'splash' 3. and for sneezing I've seen it written 'ah-choo' or 'achoo' For what purpose do you need these kinds of words for? Perhaps with a certain purpose that you need, there are better specified words for these situations.

Here is a website with a great list of onomatopoeia. http://kathytemean.wordpress.com/2009/12/29/onomatopoeia-word-list/ But you can see the list below as well.
