THE EFFECTS OF LOW FREQUENCY NOISE ON MAN AS RELATED TO THE APOLLO SPACE PROGRAM

Abstract

The purpose of this report is fourfold: (1) to present best estimates of the maximum low-frequency noise environments (5-1,000 c/s) expected inside the command module of the Apollo space vehicle during launch operations; (2) to summarize the capabilities of several existing noise sources which are available to simulate these estimated environments for laboratory and field study purposes; (3) to document known exposure histories to this type of noise including newly conducted experiments with human test subjects; and (4) from this documentation to draw conclusions concerning the significance of low frequency noise in Apollo space vehicle operations. This report is limited to considering only the noise environments estimated external to and within the Apollo command module and the significance of these environments insofar as the crew members are concerned.
