TBT: Grand Canyon Noise Measurements, September 1999

by Mary Ellen Eagan

How about a four day, all-expense paid camping trip in the Grand Canyon?  All our eight teams of four people each had to do was listen for aircraft eight hours a day.  The goal was to determine which noise model best predicted tour aircraft audibility.  Thanks to Rick Ernenwein and the late Wes Henry for making it all possible.  What a team!
