An exploratory study has been conducted to determine the feasibility of obtaining and using in-flight manikin recordings to evaluate flight helmets with respect to speech intelligibility. Intelligibility test materials were transmitted to six airborne subjects and a manikin as each was fitted with different flight helmets. Similar test materials were presented to the same six subjects in a simulated flight situation. Recordings obtained via the airborne manikin were subsequently placed back in the laboratory to the six subjects and two groups of ten listeners each. (Author)
