Evaluation of Lightweight and Low Profile Communications Devices for Respiratory Protective System 21 (RESPO 21)

Abstract : The Chemical Research, Development, and Engineering Center (CRDEC) is entering development of the next generation of respiratory protection (RESPO 21) to replace the current M40 series of protective masks. One of the design goals of this development is to improve both face-to-face and electronic communications while wearing respiratory protection. Commercial voice amplification systems being evaluated for this application are too bulky for many field applications. An evaluation of miniaturized communication systems was needed to expand the potential applications of voice enhancement.
