The close-talking microphones interfere with the suited subject\u2019s eating and drinking, and are susceptible to contamination. The communication cap needs to fit well. Caps in a variety of different sizes need to be built and maintained, e.g., 5 sizes for EMU caps. Wire fatigue for the microphone booms. These problems cannot be resolved with incremental improvements to the basic design of the CCA systems.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
