The present state of research on the effects of noise: are we asking the right questions?

A review is presented, with a bibliography of 68 items, of some effects and aftereffects of noise on other senses and on intelligence, on performance on multiple tasks, memory, computation, vigilance, signal detection, reaction time, and on industrial performance. Throughout this literature contradictions abound. Mechanisms reviewed include distraction, arousal, stress, concentration, masking of task-produced feedback, erasure of auditory store, and interference with or inhibition of articulation and rehearsal. It was concluded that it is necessary to consider complex interactions of the effects of noise with task difficulty and task proficiency of the subject, personality of the subject, time of day, food and drug ingestion, and the meaning of the noise and the previous exposure of the subject to it, whether it represents a threat or interference with work or reaction, or is in fact interesting and enjoyable. Such information must be available before generalizing.

Annoyance by aircraft noise and fear of overflying aircraft in relation to attitudes toward the environment and community.

If, as has been suggested, expressions of annoyance attributable to aircraft noise may reflect, in part, fear of aircraft overflights and possible crashes, then residents of areas where crashes have occurred should express more annoyance. To test this hypothesis, 50 residents of an Albany, New York area where an aircraft crash producing fatalities recently occurred, and 50 residents of a comparable nearby area without such a history, were asked to respond to a "Quality of Life" questionnaire. Among the items were some designed to test annoyance by noise and fear of aircraft overflights. It was predicted that those in the crash area would express more fear and would more often identify aircraft as a noise source. Factor analysis and discriminant analysis results sustained these hypotheses. A near-replication was carried out in Louisville, Kentucky; results were much the same. For the crash-area groups there was association of aircraft fear and noise annoyance responses; this was true to an apparently lesser extent for non-crash-area groups. The greater annoyance of crash groups by aircraft community noise apparently does not carry over to assessment of aircraft noise in the laboratory.

America in the 1980s: 10 major changes ahead.

At least 10 major developments will substantially change our country, our lives, our livelihoods, and our families in the 1980s. Despite all of our immediate and visible problems, if we Americans follow sensible policies of government deregulation, of capital formation, of energy conservation, and energy development, then the economic, the political, and the social future of the United States in the revolutionary 1980s is absolutely dazzling.
