Showing papers on "Annoyance published in 1969"


Journal ArticleDOI
TL;DR: In this paper, the authors quantify the relationship between duration and noise and find that doubling of duration is more annoying than doubling of noise in two spectra: random noise and a fan jet ground run-up.

TL;DR: This investigation stresses the importance of investigating possible differences in reactions in order to make valid comparisons between results of annoyance studies carried out in different countries.
Abstract: Annoyance reactions to motor vehicle noise have been studied in Sweden and Italy. Every possible care has been taken to assure that the interview forms used to measure reactions have been translated adequately. Exposure factors have been stratified strictly. Nevertheless a difference in exposure could be detected when check measurements were carried out. Despite a higher noise level in Italian homes, annoyance reactions were fewer. This investigation stresses the importance of investigating possible differences in reactions in order to make valid comparisons between results of annoyance studies carried out in different countries.

TL;DR: In this article, the need for ease of communication, privacy and freedom from annoyance determine the acoustic requirements for an office, and in particular they lead to the control of the background noise in some offices this means keeping noise levels down but in others it is necessary to introduce background noise to maximize privacy and to minimise annoyance.

TL;DR: In this article, the authors evaluated the relative annoyance of sound sources that continuously increase in frequency and/or intensity over a period of several seconds and found that signals characterized as approaching entities were judged more annoying than all other signals assuming constant average intensity and frequency content over the signal duration.
Abstract: Sound sources that continuously increase in frequency and/or intensity over a period of several seconds may be perceived by observers as approaching entities, whereas the converse is true for sources with decreasing signal characteristics. The comparative annoyance of such sounds signaling “approaching” and “receding” sources was evaluated by means of paired‐comparison judgments of several signals of 15 sec duration that continuously varied in both frequency (from 600 to 1200 or 1200 to 600 Hz) and intensity (from 70 to 100 or 100 to 70 dB). Findings clearly demonstrate that signals characterized as approaching entities were judged more annoying than all other signals assuming constant average intensity and frequency content over the signal duration. Increasing intensity influenced judgments of annoyance to a greater extent than did frequency changes. Rank order or annoyance corresponded to the hypothesis that the “approaching” characteristics of a sound source contribute significantly to its judged annoyance. The importance of these findings for the evaluation of aircraft flyover noises is discussed.

TL;DR: In this paper, it is proposed that the overall subjective effect of noise may be a combination of these and other factors; this would account for the unsuccessful attempts of most previous work to find a high correlation between an individual score on a psychological scale and physical noise measurements.

TL;DR: In this paper, noise criteria in terms of sound pressure levels and frequencies are proposed for the passengers and the crews accomodation, for the bridge and for the engine room of sea-going ships with respect to hearing conservation, audibility of whistles, speech communication, comfort and annoyance.
Abstract: Noise criteria in terms of sound pressure levels and frequencies are proposed for the passengers and the crews accomodation, for the bridge and for the engine room of sea-going ships with respect to hearing conservation, audibility of whistles, speech communication, comfort and annoyance. It is shown that the NR-noise rating curves efficiently correlate with annoyance and that sound level A in contrast to industrial noise and road traffic noise is impracticable for ship noises. A survey of acoustical measures applied in existing ships illustrates that the proposed criteria can be met.
