Prototypes of the Sonex Gundefender earplug were evaluated with reference to the ear protection capabilities of the earplug and the speech intelligibility scores obtained in both noise and quiet conditions. The medical standard V.51R earplug was used as a comparison unit. A temporary threshold shift reduction method was used for the comparison of protective capabilities. Magnetic recordings of the Modified Rhyme Test were used to obtain the speech intelligibility data. Author
