Title Effects of user insertion/donning instructions on noise attenuation of aural insert hearing protectors
Bibliographic information Apr. 1986, Vol.28, No.2, p.195-210. Illus. 23 ref.
Abstract The noise attenuation achieved with some common protective earplugs was strongly affected by the instructions for their use. Five levels of instruction were tested: (1) subjects were given no instruction all; (2) subjects were given no placement instructions, but were given a reference noise to help them judge attenuation; (3) subjects used manufacturers' on-package instructions; (4) subjects used detailed written and pictorial instructions; (5) correct insertion was demonstrated to the subjects. The earplugs differed in their sensitivity to incorrect insertion, but all types were more effective with detailed instructions or demonstrations: in some cases, attenuation was tripled by improved instructions.
