Listening for machinery malfunctions in noise while wearing ear muffs / S.E. Forshaw.: D68-25/8-1977E-PDF
"It is generally believed by personnel who work in ships' engine and boiler rooms that the noise attenuation provided by an effective ear muff will adversely affect their ability to detect those sounds that indicate real or potential machinery malfunction. Studies conducted with persons listening to speech or pure tones in noise suggest, however, that for normal-hearing persons in noise levels above 80 dB, ear muffs are probably not detrimental to the above listening task"--Abstract, page v.
