    Objectives: Air, road, and railway traffic, the three major sources of traffic noise, have been reported to differently impact on annoyance. However, these findings may not be transferable to physiological reactions during sleep which are considered to decrease nighttime recovery and might mediate long-term negative health effects. Studies on awakenings from sleep indicate that railway noise. A Laboratory Study of Subjective Annoyance Response to Sonic Booms and Aircraft Flyovers An early review (ref. 8) of laboratory studies of sonic boom effects on people indicated that Perceived Noise Level (PNL) of a level of subsonic airplane noise when judged equally annoying, and.

      At the same average noise level, the percentage of highly annoyed residents decreases in the order aircraft noise, road traffic noise, and rail traffic noise. 13 Possible explanations for these differences in annoyance have been brought forward, among them the potential threat of aircraft crashes, the problem of escaping from aircraft noise.

Laboratory study of annoyance to combined airplane and road-traffic noise. Washington, D.C.: National Aeronautics and Space Administration, Scientific and Technical Information Branch ; [Springfield, Va.: For sale by the National Technical Information. The annoyance of noise, which consisted of both separate and combined airplane and road-traffic noises, was studied.

The subjects judged each session as to how annoyed they were in the simulated living room laboratory environment and as to how annoyed they were if they heard the noise in their home during day, evening, and night : C.

SIMULATED ENVIRONMENT EXPERIMENT The experiment on annoyance due to mixed sources of train and road traffic noises was carried out in the laboratory at MTEC, which simulates a typical living room of a middle class family of the area.

A sound insulated window is provided and loudspeaker systems are concealed behind the wall curtains. This paper addresses the negative effects resulting from the exposure to road traffic noise on people's well being with a focus on annoyance.

Following the observations that noise exposures engender physiological reactions typical of stress, the non-auditory effects of noise on humans are generally viewed as being stress-related, and annoyance is one of the first and most direct reactions to.

In the present study there was a clear relationship between the proportion of individuals reporting annoyance due to road traffic noise and modelled exposure levels. This is in accordance with previous studies (Abel ; Stansfeld et al., ) A considerable number of the respondents reported annoyance already in the interval dBA.

noise sensitivity, attitudes towards the source), questions concerning residential conditions (e.g. Earlier studies developed annoyance models combining aircraft and road traffic noises, but investigated only physical metrics such as Ldn and Lden without considering frequency characteristics.

This polysomnographic study was designed to systematically compare the effects of air, road, and rail traffic noise on sleep. The study design was carefully balanced according to the number of noise events, maximum SPL, equivalent noise level Leq, study night, and prior noise annoyance to enable a “fair” comparison.

combined noise exposure from aircraft and road traffic. The purpose of this study is to assess the effects of dominant noise source with relatively high sound exposure level on total annoyance and compare the total annoyance from combined noise exposure with annoyance from single noise.

Separate, non-identical curves were found for aircraft, road traffic, and railway noise. Table 1 illustrates that, for a DNL of 65 dB, the percent of the people forecasted to be Highly Annoyed is 28% for air traffic, 18% for road traffic, and 11% for railroad traffic. There is a lack of studies assessing the exposure-response relationship between transportation noise and annoyance in North America.

Our aims were to investigate the prevalence of noise annoyance induced by road traffic, trains and airplanes in relation to distance to transportation noise sources, and to total environmental noise levels in Montreal, Canada; annoyance was assessed as noise. Current literature suggests that wind turbine noise is more annoying than transportation noise.

To date, however, it is not known which acoustic characteristics of wind turbines alone, i.e., without effect modifiers such as visibility, are associated with annoyance.

The objective of this study was therefore to investigate and compare the short-term noise annoyance reactions to wind turbines. Noise legislation in Austria does not provide an assessment of the cumulative effect of noise from different sources.

The desire of citizens for a total noise assessment is getting stronger. Within the pilot project “Gesamtlärmbetrachtung” (Total Noise Investigation) Innsbruck, data from face-to-face interviews were correlated with exposure data from road, rail and air traffic noise.

Road traffic and related noise is a major source of annoyance and impairment to health in urban areas. Many areas exposed to road traffic noise are also exposed to rail and air traffic noise. The resulting annoyance may depend on individual/neighborhood socio-demographic factors.

Nevertheless, few studies have taken into account the confounding or modifying factors in the relationship between. The number of noise events and LAS,eq were kept constant. Each morning noise annoyance questionnaires and performance tasks were administered.

Aircraft noise annoyance ranked first followed by railway and road noise. A possible explanation is the longer duration of aircraft noise events used in this study compared to road and railway noise events.

The limitations of the first studies of aircraft noise disturbance and annoyance carried out in the s were recognised at the time and increasing numbers of similar studies were then carried out at different locations around the world.In the present study, community annoyance in urban spaces was obtained by social survey and construction noise as well as road traffic noise was dealt with as noise source.

Standardized questions to obtain the noise annoyance were applied and syn-thesis curves for the relationship between noise exposure and annoyance were de-rived.RESEARCH Open Access Transportation noise and annoyance related to road traffic in the French RECORD study Julie Méline1,2*, Andraea Van Hulst3,4, Frédérique Thomas5, Noëlla Karusisi1,2 and Basile Chaix1,2 Abstract Road traffic and related noise is a major source of annoyance and impairment to health in urban areas.
