The US Navy's Office of Naval Research is studying new ways to reduce the impact of jet noise on carrier deck crews. The Navy says that jet noise from tactical aircraft can reach 150 decibels on the flight line, which is well above the safe limits for hearing. Factories, for example, are required to institute a hearing protection program once noise levels reach 85 decibels, the Navy says.
The ONR hopes its project will help to create new approaches to mitigate jet exhaust noise which will result in safer noise environments. That should also help in reducing noise complaints reported in communities near military bases.
ONR is awarding about $4 million to researchers at Brigham Young University, California Institute of Technology, Cascade Technologies, Innovative Technology Applications Co., University of Illinois, University of Mississippi, Pennsylvania State University and Virginia Tech for the effort. NASA is also chipping in a few dollars...
Hearing loss is no joke, and it's imperative that folks wear proper hearing protection working around aircraft. Something I learned the hard way.
Anyway, here is picture of F-22 Raptor tail number 09-4191 flying home to Langley from the Lockheed Martin's factory in Marietta, Georgia. There are three more left to go, last one leaves the nest on May 2. You should wear hearing protection if you are standing near an operating Raptor--see it's not just an excuse to post an F-22 shot.
Also the F-35 is pretty goddamn loud... Yes, heard it in person at Pax and on the USS Wasp.
