LS-71011A, ACOUSTIC NOISE CONTROL AND ANALYSIS PLAN FOR HUMAN RESEARCH FACILITY PAYLOADS AND RACKS (19 OCT 2001)

LS-71011A, ACOUSTIC NOISE CONTROL AND ANALYSIS PLAN FOR HUMAN RESEARCH FACILITY PAYLOADS AND RACKS (19 OCT 2001)., The Human Research Facility (HRF) is a facility class payload that consists of a suite of generic human life sciences hardware needed to support a multidisciplinary research program that encompasses basic, applied, and operations research. The HRF will include equipment to support research to understand the effects of weightlessness and the space environment on human systems and to develop, where appropriate, methods to counteract these effects to ensure safe and efficient crew operations. This document provides a general outline of the acoustic control plan and analysis approach. Section 2 describes the ISS acoustic design requirement. Section 3, introduces the general theory of sound propagation and analytical formulations to LS-71011 - 05/30/01 1-2 compute SPLs. Section 4 describes the acoustic analysis approach which will be used to perform the rack level, component level analysis process, and component level suballocation procedure. Section 5 investigates the methods of noise control. A summary is provided in Section 6. Appendix A describes the noise measurement procedures for ISS Government Furnished Equipment (GFE) equipment and payloads. This appendix was provided by JSC-SP3. The document, JSC-26218, Spacelab Life Sciences 2 Acoustic Analysis Report [21], is an example of a typical acoustics analysis involving several sources located in different locations in an enclosed volume operated intermittently or continuously according to a timeline. In case of conflicts between this document and LS-71000, HRF Program Requirements Document [22], LS-71000 takes precedence
