You call those horns? Now these are some horns!

I was going through some old photos and found these of the acoustic testing chamber at the NASA Goddard Spaceflight center in Greenbelt, MD. One is of one of the smaller horns they use in testing. The others are of the horn outlet in the testing chamber, and another is of the backs of the horns sticking out of the adjacent wall. If I remember correctly the chamber is used to test instrument and component durability in simulated launch and space conditions. I'm guessing they get pretty loud....
