Abstract:

This report presents the measured acoustical noise environment for the interior of the C-141A aircraft and a description of the production soundproofing treatment as required by MIL-A8806. The measured acoustical noise environment for the required flight conditions is well below specification limits in most octave bands. There are a few insignificant instances where the measured noise levels exceed the specification by one or two decibels. Author
