Propellant Handler's Ensemble In-Suit Noise Measurements

Abstract

The USAF OEHL requested by HQ Space Division (AFSC) to measure octave band noise levels inside the new propellant handler's ensemble (PHE) for use by the Space Shuttle Activation Task Force (SATAF) at Vandenberg AFB CA. The noise levels were necessary to determine if the PHE meets the requirements of paragraph 3.1.3.6.3 of the suit specification (79K20409) and to assess the potential for possible interferences with either internal or external voice transmissions. The PHE met the specification levels in several but not all operating categories. Speech interference levels were also dependent on the operating category.
