Crickets!
A course of crickets intrigued our dinner party guests and we were able to use acoustic math and a the decibel level ~40dB provided by Decibel X to estimate their distance, 500-1000 feet away, about the distance of the nearby trees. Mystery solved. Five stars.

Cool Stuff!
This app has become very useful for getting a baseline for volume of instruments in the Church Choir. Also useful for getting an idea of vocal ranges.
