KIMA: Noise: A visual sound installation on urban noise

KIMA: Noise is a participatory art piece inviting audiences to explore impact of urban noises interactively. Using specific urban sound sources, the audience experiences noise as spatial soundscapes, responding to it, physically engaging and interacting with it. KIMA: Noise creates awareness for the phenomenon of noise pollution. The paper looks at preeminent research in the field, and draws conclusions of how sound affects us as individuals. The art project KIMA: Noise is introduced technically and conceptually

The study - a field investigation - deals with the effects of rail traffic-induced vibrations on people living near railway. The effects of three factors influencing the vibration annoyance are analysed: (1) vibration severity, (2) number of trains passing and (3) the simultaneous noise level. Additionally the results of the field investigation are discussed from the aspect of possible vibration guideline values. The statistical analyses of the various data (such as vibration load, noise level and sociopsychological data) showed: the overall relationship between vibration intensity and annoyance is rather weak. Furthermore the effect of vibration intensity is smaller for people suffering from simultaneous higher noise levels than for those suffering from lower noise levels (vibration x noise interaction). It is proposed that vibration guideline values should not be based on the vibration levels of the maximum individual occurences, but rather on reference values based on the energetic mean value of all vibrations occuring during the period under consideration.

Short-term annoyance from nocturnal aircraft noise exposure: results of the NORAH and STRAIN sleep studies

Purpose The German Aerospace Center (DLR) investigated in the NORAH sleep study the association between a distinct change in nocturnal aircraft noise exposure due to the introduction of a night curfew (11:00 pm-5:00 am) at Frankfurt Airport and short-term annoyance reactions of residents in the surrounding community. Exposure-response curves were calculated by using random effects logistic regression to evaluate the aircraft noise-related parameters (1) number of overflights and (2) energy equivalent noise level LASeq for the prediction of short-term annoyance. Data of the NORAH sleep study were compared with the STRAIN sleep study which was conducted by DLR near Cologne-Bonn Airport in 2001/2002 (N=64), representing a steady-state/low-rate change. Methods The NORAH sleep study was based on questionnaire surveys with 187 residents living in the vicinity of Frankfurt Airport. Noise-induced short–term annoyance and related non-acoustical variables were assessed. Nocturnal aircraft noise exposure was measured inside the residents` home. Results A statistically significant rise in the portion of annoyed residents with increasing number of overflights was found. Similarly, the portion of annoyed subjects increased with rising LASeq. Importance of the frequency of fly-overs for the prediction of annoyance reactions was emphasized. The annoyance probability was significantly higher in the NORAH than in the STRAIN sleep study. Conclusions Results confirm the importance of both acoustical parameters for the prediction of short-term annoyance due to nocturnal aircraft noise. Quantitative annoyance models that were derived at steady-state/low-rate change airports cannot be directly applied to airports that underwent a distinct change in operational and noise exposure patterns
