“…As pointed out by Jansen & Rey ( 1962) the decrease of fingerpulse amplitudes becomes greater with increasing intensity as well as with increasing band width According to an increasing number of stimulated nerve fibers that means with an increasing number of impulses per second a greater number of impulses arrive at the vegetative centers in the brain stem causing a stronger reaction The missed relation between the FPA parameters and the boom intensities in this study may be caused by different factors As described by Miederhoff ( 1974) the on-reaction becomes greater and occurs earlier when the rise time of noise pressure decreases The rise time of the sonic booms is extremely short ( 5 msec in average) so that the organism may be unable to respond adaequately On the other hand, the range of intensities ( 80-89 d BlAl) may be too small to cause different reactions (Ludlow & Morgan, 1972) As pointed out by Jansen ( 1967) the increase or reaction becomes smaller with increasing intensities; the minimum occurs within the range of intensities used in this study.…”

SummaryIn two experimental series ( 19 53 nights, respectively, in 2 different persons in each series; testtime 10 30 p m to 3 00 a m ) fingerpulse amplitudes after sonic booms were recorded during sleep In the first 3 nights the subjects slept undisturbed by noise In the following 11 and 30 nights, respectively, sonic booms were applied alternately 2 or 4 times In the main series, after 10 more nights without noise, 4 nights with 8 and 16 sonic booms alternately followedThe last 6 undis- Sonic booms induced a decrease in fingerpulse amplitudes, which begin 3 sec after the onset of the stimulus The minimum occurs after 8 sec, followed by an increase towards the preboom value The reduction of the fingerpulse amplitudes is very significant (P 1 %) from the 4th to the 22nd sec This reaction was analyzed with special regard to the following factors:1 Intensity: Due to the very short rise time of noise intensity there was no significant correlation between the maximum intensity of each boom and the decrease of fingerpulse amplitudes.2 Exogenic variables: There are no significant connections between postboom fingerpulse amplitudes and noiseless time before the sonic boom, the duration of the test series, and the ambient temperature.3 Endogenic variables: No correlation could be found between the stage of sleep and the reaction On the contrary, a very significant correla-57 tion was found between the reduction of fingerpulse amplitudes and the pulse rate before boom With increasing pulse rate the extent of reaction becomes smaller.

“…Self reports of subjective sleep quality have been collected in a number of studies, 9 of which were laboratory (including quasi-lab), and 3 were field surveys (Collins and lampietro, 1973;Eberhardt and Akselsson, 1987;Fidell and Jones, 1975;Griefahn and Gros, 1986;Herbert and Wilkinson, 1973;Johnson, 1973;Ludlow and Morgan, 1972;Lukas et al, 1971;Lukas et al, 1972;Schneider, 1973;Griefahn and Muzet, 1978). The importance of quality of sleep to health remains unclear.…”

3 (1977) 165-182. A survey of the different types of shift-work systems in use, and the incidence of shift work in different industries and countries, is followed by a discussion of (a) the effects of shift work on health and (b) the physiological problems raised by the phase-shifting of the circadian cycle in night workers. Summaries of the existing knowledge of the effects of shift work on performance efficiency, accidents, and family and social life are then given, and a set of criteria for designing optimal shift systems is proposed. Next, the questions of selection for shift work and the provision of health services for shiftworkers are discussed. Finally, the need for further research on the problems of shift work is explained, and suggestions are offered on the lines such research should follow.Key words: accidents, attitudes, circadian r'hythms, gastrointestinal disease, interpersonal relationships, performance efficiency, personnel selection, psychosocial factors, shift work, sleep.The literature on shift work is ,considerable. Most of the available reports ,concern a particula'r approach to the problem. However, a more general view is given in some recent publications (22, 52,68,73, 90), and several international symposia have been devoted to this subject (e.g., 24, 27, 93, 94). 'I1he present paper is a review of the most important and generally a,ccepted facts on shift work and its possible effects on health and related factors.Institute of Work Physiology at the Univel'sity of Dortmund, Federal Republic of Gel'many.
