The Design of a Quality System to Support NASA Glenn Research Center Acoustical Testing Laboratory

摘要

The NASA Glenn Research Center (GRC) recently constructed an acoustical testing laboratory for use in supporting the noise control needs of the International Space Station (ISS) project. In support of the acoustical measurements conducted in the NASA GRC Acoustical Testing Laboratory (ATL) a quality system, designed in accordance with the requirements of ISO 17025, "General Requirements for the Competence of Calibration and Testing Laboratories", was been developed by JGS Consulting under contract to NASA GRC. This quality system currently supports sound power level determinations in accordance with ISO 3744, "Determination of sound power levels of noise sources using sound pressure - Engineering method in an essentially free field over a reflecting plane". The quality system is currently being expanded to include NASA procedures for verification of sound pressure level emissions of space flight hardware. This paper provides background information on the facility and an overview of the quality system that was developed to support the laboratory operations.
