Abstract This report describes the methods used, and gives the results of a study on the influence of sound level, use of earplugs, speech and understanding of verbal communications, the reactions between the speaker and listener, and type of communication, on the understanding of speech communications between 180 pairs of speakers and listeners. Conversation level was reduced by 4dB when hearing protection was used, understanding of verbal messages was reduced by 40%, and exchange of information was considerably slowed down, in comparison to results when no hearing protection was worn.
