How Loud is it in the Pilothouse?

The following noise level readings were taken while underway using an Ipod Touch 4G running Sound Level(TM)—a free app. I was standing in the middle of the pilothouse, facing forward. The Touch was held upright and was about 5'4" high . Hmm, looks like Nellie has a resonance problem at 800 rpm ;-)
