Many ear defenders, originally designed for protective purposes only, have been used as communication headsets by the installation of acoustic apparatus. Six defender communication headsets in common use and one semi-insert device were tested for intelligibility in a noise environment created by a jet engine. Trained listeners copied prerecorded phonetically balanced (PB) word lists. This paper details the training and testing procedures, including the monitoring of the noise environment. Results are given showing the relative performance of each of the defender headsets.
