The Nova Scotia Museum of Natural History is currently planning an exhibit about sounds in nature. We're interested in looking at how sounds are produced and received by living organisms, and their functional significance. We'll also be including ambient sounds - like waves breaking on a beach - and exploring the incorporation of natural sounds into human culture. We intend to make the exhibit as interactive and "hands-on" as possible to give visitors an opportunity to hear, manipulate and produce sounds and to compare visually the spectral qualities of different organisms. To avoid re-inventing too many wheels, I would appreciate hearing about exhibits that you have seen (or made) that have incorporated sound in an interactive way, any presentations you felt were effective, and any information you could supply about sources of natural sound. We're also interested in discovering durable (and inexpensive) technologies for digitally recorded sound that would survive intensive use. I'd be pleased to hear of any current research in this field that you think would lend itself to an interactive exhibit and any creative ideas you might have about one.
