Abstract

This paper reports the method for evaluating the speech intelligibility . of ear protectors.Twenty subjects wearing 3 types of ear plugs ("MT-86", "65", "85-Ⅱ" ear plugs) were presented with stable 50-Chinese-word signals. The results show that the intelligibility was higher with "MT-86" than with "65" and "85-Ⅱ ", and this method was a better measure to evaluate the influence of ear protectors on the intelligibility of speech.
