The effect of group versus individual hearing loss prevention (HLP) training on the attenuation performance of hearing protection devices (HPDs) was investigated. A subject-fit methodology, which gives naive listeners access only to the instructions printed on the HPD product label, was used to determine real-ear attenuation at threshold (REAT) at thirdoctave noise bands between 125-8000 Hz. REAT measurements were augmented by use of the HLP Attitude-Belief survey, a self-assessment tool developed by the National Institute for Occupational Safety and Health. Participants were randomly assigned to one of four experimental groups, consisting of 25 listeners each. A short multimedia program was presented to listeners, with half randomly assigned to individual training and the other half assigned to group training. Results showed training to have a significant effect, for two types of HPDs (formable and premolded) on real-ear attenuation and attitude, but, importantly, there was no difference between group and individual training.
