You guys have it!

Been using our hearing protection for 8 to 12 hours a day. You guys have it! Works great, we have good clear communications, damps the noise to a bearable level. Previously a few hours in the engine room with what we had for hearing protection would trigger a good headache from the noise. Not anymore. We were coming out of the engine room to communicate, wave flashlights at each other or pass notes. Don't have to do that anymore. Great job folks!
