1 “Highly Annoyed: One mark multiple meanings” Eveline Maris Leiden University The Netherlands

2 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria2 Research problem -Problem of noise omnipresent -Abatement strategies address dB’s

3 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria3 Annoyance Question In how far does the sound annoy you? 1=not at all (…) 7=extremely

4 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria4 Prevalence of consequential degree of annoyance at various average levels of transportation sound exposure (Ldn) as observed at 453 sites (Source: Fidell, 1992). Day-Night Average Sound Level, dB Proportion of respondents Highly Annoyed by noise

5 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria5 Research problem -Problem of noise omnipresent -Abatement strategies address dB’s -Annoyance is correlated with nonacoustic factors -Is abatement via nonacoustics possible? Q: Are (social) nonacoustic factors a contributory cause of noise annoyance?

6 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria6 Social nonacoustic factors Man-made sound: “You expose Me” Social Context: = Relational aspects of exposure situation –An aspect of social context is Procedure –A quality/characteristic of procedure is Fairness Theory of Social Justice (e.g. Tyler & Lind, 1992)

7 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria7 SOUND SOCIAL SETTING External processes Internal processes (physical & social) (psychological) The Model Disturbance Control Annoyance (stress) + -

8 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria8 Research Questions Do social nonacoustical factors have a causal relationship with noise annoyance? –> Unfair exposure procedures cause an increase in annoyance Does the influence of social nonacoustical factors depend on sound level? –> The fair procedure effect is moderated by sound level

9 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria9 Experiment (1) Prerequisites –The noise should cause annoyance –Disturbance of activity is important aspect of annoyance  all subjects same activity  activity that is likely disturbed by sound –Manipulation of fairness strong link between source and subject, and linked with sound itself

10 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria10 Experiment (2) 2 x 2 Design Fairness (Y / N) vs. Loudness (50 dB / 70 dB) Manipulation of fairness and sound 15 minutes exposure during reading task Dependents: Annoyance (after 1 minute, after 15 minutes) Disturbance Perceived Control Population: 76 students

11 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria11 Experiment (3) Flow of experiment –Cover story: noise & performance –Frame of reference for sound level –Fairness: being asked to express preference which was said to be taken into account where possible –Task: internal motivation to perform (exam), identical for all participants –Annoyance question after 1 minute of exposure and directly after end of reading task (15 minutes)

12 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria12 ANOVA effect of acoustical factor Main effect Fair (n.s.) Main effect Sound F(1,72)=9.42 p=.003 η²=.12 Sound*Fair (n.s.) (obs.power.17) With covariate: Sound*Fairness F(1,68)=5.9 p=.018 η²=.079

13 Young Researchers Workshop, 18th. IAPS conference, July 5-6, 2004, Vienna, Austria13 Conclusions The fairness of procedure can have a causal effect on annoyance with noise The influence of procedural fairness on noise annoyance depends on sound level Abatement policy makers should be aware of possible effects of procedural fairness
