An inter-laboratory investigation of ANSI standard fitting protocols, sample size, subject and experimenter gender, and trial on the real-ear attenuation of two types of earplugs
Identical experiments were conducted between two acoustical-testing laboratories to determine the inter-laboratory differences of using two different hearing protection device (HPD) fitting procedures for testing the real-ear attenuation at threshold (REAT) of a popular vinyl foam earplug and a mult...
