Abstract : Blast protection and attenuation offered by subject device were slightly inferior to standardized V51R ear protector. For periods of wear of one hour or longer the Silents were uncomfortable and irritating. Universal size arrangement of subject plug is a desirable feature of the subject device. The principle of closing the ear canal entrance rather than depending upon an insert into the canal is desirable, providing a satisfactory acoustic seal is maintained. (Author)
