TL;DR: Noise and its disturbing effect - of an extensive study carried out in 15 landscaped offices in Switzerland and the results of a questionnaire which examined annoyance, sources of noise, ability to concentrate, and causes of distractions are considered.

TL;DR: Data on aircraft annoyance from a French study of 1965–1966 have been re-evaluated in the light of findings from a recent Scandinavian study and show that reduction of noise of individual aircraft is of primary importance in reducing annoyance.

TL;DR: In this article, a new methodological field-survey approach has been developed to provide the precise information which is needed by noise abatement engineers of the variable human response to different types and degrees of noise exposure.
Abstract: Gross measures of community annoyance with intrusive noises have been made in a number of real environment surveys which indicate that aircraft noise may have to be reduced 30-40 EPNdb before it will generally be considered acceptable. Interview studies, however, cannot provide the precise information which is needed by noise abatement engineers of the variable human response to different types and degrees of noise exposure. A new methodological field-survey approach has been developed to provide such information. The integrated attitudes and experiences of a random sample of subjects in the real environment are obtained by a prior field survey. Then these subjects record their more precise responses to controlled noise exposures in a new realistic laboratory. The laboratory is a sound chamber furnished as a typical living room (18 ft x 14 ft) and subjects watch a color TV program while they judge simulated aircraft flyovers that occur at controlled levels and intervals. Methodological experiments indicate that subjects in the laboratory have the sensation that the airplanes are actually moving overhead across the ceiling of the chamber. It was also determined that annoyance judgments in the laboratory stabilize after three flyovers are heard prior to a judgment of annoyance.

TL;DR: In this paper, the authors investigate the role of noise level distribution in the negative effect of URBAN TRAFFIC NOISE on the overall negative attitude of drivers towards traffic noise.
Abstract: JURY LISTENING TESTS WERE CONDUCTED TO DETERMINE QUANTITATIVELY THE ROLE OF NOISE FLUCTUATIONS IN ESTABLISHING THE TOTAL SUBJECTIVE ANNOYANCE OF URBAN TRAFFIC NOISE BOTH GAUSSIAN AND NON-GAUSSIAN NOISE LEVEL DISTRIBUTION HAVE BEEN STUDIED THE NOISE POLLUTION INDEX, IN THE FORM L SUB NP EQUALS L SUB EQ PLUS KO, APPEARS AS AN ACCEPTABLE PHYSICAL MEASURE FOR THE SUBJECTIVE ANNOYANCE OF TRAFFIC NOISE HEARD INDOORS THE COEFFICIENT K IS SENSITIVE TO A VARIETY OF FACTORS PECULIAR TO A GIVEN LISTENING SITUATION /AUTHOR/

TL;DR: In this article, the authors defined a descriptor to provide a means of relating TRAFFIC NOISE to human response, and defined the characteristics of a sound that are unfamiliar to any human response.
Abstract: A DESCRIPTIVE APPARATUS IS FORMULATED TO PROVIDE A MEANS OF RELATING TRAFFIC NOISE TO HUMAN RESPONSE. THE BASIC VARIABLES OF A SOUND THAT ARE INTRINSIC TO ANY ELEMENT OF HUMAN RESPONSE (MAGNITUDE, FREQUENCY DISTRIBUTION, AND TEMPORAL CHARACTERISTICS) ARE SPECIFIED. MAXIMUM NOISE LEVELS THAT PERMIT SATISFACTORY SPEECH AND LISTENING ENVIRONMENTS FOR VARIOUS TYPES OF SPACES ARE GIVEN; IT WAS FOUND TO BE IMPOSSIBLE TO PROVIDE SIMILAR LEVELS TO PREVENT SLEEP INTERFERENCE. IT WAS CONCLUDED THAT SPECIFYING CRITERIA FOR DIFFERENT LEVELS OF ANNOYANCE IS HIGHLY DEPENDENT ON THE NATURE OF THE INTRUDING NOISE, THE INDIVIDUAL, LOCAL OR REGIONAL ATTITUDES, AND EVEN THE SOCIOECONOMIC STATUS OF THE LISTENERS.
