Interactive Sound Fence Project

I am working on a community based arts project in New Zealand. I am designing a fence which will go around a park area and I wanted to include some motion activated sounds. The sounds will be recordings of wildlife in the park area and will be triggered by people walking passed specific parts of the fence.

Any suggestions as to the best way to tackle this?

Thank you in advance
Simon

One way would be to use a PIR sensor, and attach its trigger output to a voice recorder chip like the one jaycar sells.
