sound wav

[Michele]

Is it possible to add a wav sound only on the exit of a site?
I've tried every possible way to write the html that I can think of but can't figure it out.

Only way I can think of doing it is by having a popunder with a wav in it, but I doubt anyone is going to leave the popunder open long enough for a wav to download and play. Most people close them as soon as they open
