Noise pollution resources compendium

A compendium is presented of documents on noise. The articles presented are categorized in the following sections: noise sources, noise detection and measurement, noise abatement and control, physical effects of noise, psychological and physiological effects of noise, noise regulations and standards, patents and contracts, and noise research.

Construction and application of a questionnaire for the social scientific investigation of environmental noise effects

A social psychological questionnair has been developed to study the effects of environmental noise and was applied to 636 people living in 19 different areas of Hamburg. The theoretical foundations and the statistical means employed in its development are described. Four main reactions to noise are isolated statistically, and it is determined that these are moderated by several intervening variables, chief of which are coping capacity for noise, the perceived dangerousness of the noise souce, other daily loads and the individual's liability.

Issues in life support and human factors in crew rescue from the ISS

The design and development of crew emergency response systems, particularly to provide an unplanned emergency return to Earth, requires an understanding of crew performance challenges in space. The combined effects of psychological and physiological adaptation during long-duration missions will have a significant effect on crew performance in the unpredictable and potentially life-threatening conditions of an emergency return to Earth. It is therefore important that the systems to be developed for emergency egress address these challenges through an integrated program to produce optimum productivity and safety in times of utmost stress. Fundamental to the success of the CRV is the Environmental Control and Life Support System (ECLSS), which provides the necessary conditions for the crew to survive their return mission in a shirtsleeve environment. This article will discuss the many issues in the design of an ECLSS system for CRV and place it in the context of the human performance challenges of the mission.

Aviation accidents and the theory of the situation

Social-psychological factors effecting the performance of flight crews are examined. In particular, a crew member's perceptual-psychological constructs of the flight situation (theories of the situation) are discussed. The skills and willingness of a flight crew to be alert to possible errors in the theory become critical to their effectiveness and their ability to ensure a safe flight. Several major factors that determine the likelihood that a faulty theory will be detected and revised are identified.

Space analogue studies in Antarctica

Medical research has been carried out on the Australian National Antarctic Research Expeditions (ANARE) for 50 years. As an extension of this program collaborative Australian/United States research on immunology, microbiology, psychology and remote medicine has produced important data and insight on how humans adapt to the stress of extreme isolation, confinement and the harsh environment of Antarctica. An outstanding analogue for the isolation and confinement of space missions (especially planetary outposts), ANARE has been used as an international research platform by Australia and the United States since 1993. Collaborative research has demonstrated a lowered responsiveness of the immune system under the isolation and confinement of Antarctic winter-over; a reduction of almost 50% in T cell proliferation to mitogen phytohaemogglutinin, as well as changes in latent herpesvirus states and the expansion of the polyclonal latent Epstein-Barr virus infected B cell populations. Although no clinically significant disease has been found to result from these immune changes, research is currently assessing the effects of psychological factors on the immune system. This and associated research performed to date and its relevance to both organisations is discussed, and comment made on possible extensions to the program in both medical and other fields.

Effects of prolonged exposure to pure oxygen on human performance

In view of the pure oxygen atmosphere selected for Project Mercury, and in anticipation of subsequent manned space missions of increasing duration, it was apparent that there was a need to obtain more extensive physiological data on the prolonged effects of pure oxygen environments on the crews. This study, conducted by Republic Aviation Corporation under Contract NASR-92, was initiated in collaboration with General Charles Roadman, USAF (MC), Director of Aerospace Medicine (formerly the Office of Life Sciences, NASA Headquarters), and his staff in an effort to provide a greater breadth of scientific data on the prolonged effects of such an environment on human performance. Although the 5 psi environment of Project Mercury was the focal point of the study, a broader appraisal of the effects of pure oxygen in the absence of nitrogen was attempted by including studies at 7.4 psi and 3.8 psi in addition to a control group at sea level atmospheric conditions. After award of the contract, the technical monitoring of the study was provided by the Manned Spacecraft Center, Houston, Texas, where Mr. Edward Michel served as monitor and coordinator for these and related studies subsequently established in laboratories of the U.S. Navy and U. S. Air Force.
