This presentation reviews current acoustical issues relevant to the design of future NASA Spacesuits, based on measurements conducted in the current Mark III advanced prototype surface suit, and proposes solutions for improving voice communications. Methods for mitigating problems including noise from the air supply, structure-borne noise from the suit, and detrimental acoustical reflections are reviewed.
