Sound Level Meter

The sound level meter is provided to determine on-orbit acoustical noise levels in the cabin. Depending on the requirements for each flight, the flight crew is required to take meter readings at specified crew compartment and equipment locations. The data obtained by the flight crew is logged and/or voice recorded. The meter is operated by four 1.5-volt batteries.
