Measures of 3M(TM) E-A-R(TM) Classic Hearing Protection Device in Accordance with Method 1 of ASA/ANSI S3.71-2019, "Methods for Measuring the Effect of Head-worn Devices on Directional Sound Localization in the Horizontal Plane"

Abstract

This manuscript reports the effect of the 3M(TM) E-A-R(TM) Classic Earplug on directional sound localization in the horizontal plane when tested in accordance with Method 1 described in ASA/ANSI S3.71-2019 Methods for Measuring the Effect of Head-worn Devices on Directional Sound Localization in the Horizontal Plane. Results indicate that, when properly fit and functional, the 3M(TM) E-A-R(TM) Classic will result in errors in directional sound localization in the horizontal plane 24.6% of the time (21.4% higher than baseline error-rate).
