Direct Determination of the Adequacy of Hearing Protection for Use with the VIPER,

Abstract

During developmental testing it was determined that the VIPER antitank weapon produced impulse noise which exceeded the maximum levels permitted by MIL-STD-1474. In order to proceed with operational tests, it was necessary to determine whether adequate hearing protection could be provided. This study involved the exposure of 38 volunteers to two rounds of VIPER fired in rapid succession while wearing EAR(TM) earplugs. The average exposure peak level was 181 dB SPL. Audiograms were taken before and after exposure. No detectable changes in hearing were observed in the group of volunteers. From this, it was concluded that Ear (TM) earplugs provide adequate protection for at least two rounds of VIPER.
