Intelligibility Test of Communication Ear Defenders in an Area of Extremely High Intensity Noise

Document Thumbnail

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. The purpose of the test was to provide comparative data on the performance of the headsets in the given environment.
