Even in high noise environments, the receipt of auditory signals is necessary to perform many tasks. Hearingprotection devices (HPDs) are often employed in these environments to attenuate unwanted noise and preventhearing loss. However, many HPDs not only attenuate undesirable sounds but also essential sounds, such as vocalsignals. Furthermore, when people wear HPDs, they often reduce their vocal output. This results in the listenerhaving a more difficult time hearing and/or understanding what the talker is saying. The goal of this pilot study wasto assess some of the effects of different types of HPDs on speech communication.
