Joint Service Aircrew Mask (JSAM) - Joint Strike Fighter (JSF): Speech Intelligibility Performance

Abstract

Speech intelligibility (SI) measurements were conducted in accordance with American National Standards Institute (ANSI) S3.2 Method for Measuring the Intelligibility of Speech over Communication Systems on the Joint Service Aircrew Mask (JSAM) Joint Strike Fighter (JSF) with the F-35 Lightning II Generation II (Gen II) Helmet Mounted Display (HMD) flight helmet. SI performance measurements were also collected with EAR Classic foam earplugs and CEP earplugs worn in combination with the helmet and hood. The objective of these measurements was to determine if the JSAM-JSF performance specification requirements were being met: >/= 75%. The SI scores for all configurations that included an EAR Classic foam earplug in the system (helmet alone or helmet with hood) fell far below the acceptable requirement with scores ranging from 4% to 16%. However, configurations that included communication earplugs in the system far surpassed the SI requirement with an acceptable performance of 88%.
