Irritability following traumatic brain injury: Divergent manifestations of annoyance and verbal aggression

Abstract: Primary objectives: To evaluate irritability following traumatic brain injury.Research design: A prospective study was conducted at a level I trauma centre.Methods and procedures: One hundred and forty-four participants, which included 80 healthy subjects and 64 patients suffering from TBI, were recruited. Irritability was assessed by the National Taiwan University Irritability Scale (NTUIS) from patients themselves and their families.Main outcomes and results: the results showed 14.8% of patients and 29.4% of their families reported patients’ problems of irritability. Meanwhile, both self-reported and family-reported irritability post-injury were significantly higher than those reported by the healthy subjects. When evaluating two sub-components of irritability, respectively, both family- and self-reported post-injury annoyance were significantly higher than the pre-injury one, while the self-reported post-injury verbal aggression was not.Conclusions: TBI patients have remarkable problems of irritability...

Ground-Borne Noise and Vibration in Buildings Caused by Rail Transit

Abstract: Ground vibration produced by rail transit systems can be annoying to nearby building occupants when they perceive some combination of feelable vibration, re-radiated sound, and vibration-induced rattling of household paraphernalia. Community response to rail-induced ground vibration has not been extensively researched. While the well-known Schultz dosage-response curve is routinely used to predict the prevalence of annoyance produced by airborne transportation noise, no similar relationship has gained widespread acceptance for noise and vibration due to ground vibration. The principal goal of the present research was to develop a dosage-response relationship useful for predicting community annoyance due to ground vibration produced by rail transit systems. This report documents the research conducted under the Transit Cooperative Research Program D-12 project, including a literature review, development of the study design, conduct of telephone interviews and vibration measurements, and data reduction and analyses. Telephone interviews were conducted with 1306 individuals in five North American cities: New York, Sacramento, Dallas, Toronto and Boston. Field measurements were made in each city to estimate vibration and noise exposure at each interview location. The work produced several dosage-response relationships between vibration/noise exposure and annoyance. When compared to the current noise and vibration criteria specified by the Federal Transit Administration (FTA), the dosage-response analysis predicted a probability of 0.05 to 0.10 that a D-12 respondent would be highly annoyed by vibration and noise at the current FTA criterion levels.

Annoyance of Time-Varying Road-Traffic Noise

Abstract: The aim of the study was to investigate how the time structure of a road-traffic affects the noise annoyance judgment. In a psychoacoustic experiment, the listeners judged noise annoyance of four road-traffic noise scenarios with identical numbers of vehicles and LAeq,T value but different time structure of a road traffic. The traffic structure varied from even to highly clustered across different scenarios. The scenarios were created in the laboratory from a large set of a single vehicle pass-by recordings. The scenarios were additionally filtered with filters corresponding to a typical window transfer function to simulate the situation inside the building. The experimental results showed that there is a significant difference in annoyance judgment for different traffic structures with the same LAeq,T value. The highest annoyance ratings were obtained for even traffic distribution and the most clustered distribution resulted in the lowest annoyance rating. These results correlated well with the averaged loudness, whereas the percentile loudness (N5) and level (L5) predict the opposite results.

Industrial wind turbines and adverse health effects.

Abstract: Introduction Some people living in the environs of industrial wind turbines (IWTs) report experiencing adverse health and socioeconomic effects. This review considers the hypothesis that annoyance from audible IWTs is the cause of these adverse health effects. Methods We searched PubMed and Google Scholar for articles published since 2000 that included the terms "wind turbine health," "wind turbine infrasound," "wind turbine annoyance," "noise annoyance" or "low frequency noise" in the title or abstract. Results Industrial wind turbines produce sound that is perceived to be more annoying than other sources of sound. Reported effects from exposure to IWTs are consistent with well-known stress effects from persistent unwanted sound. Conclusion If placed too close to residents, IWTs can negatively affect the physical, mental and social well-being of people. There is sufficient evidence to support the conclusion that noise from audible IWTs is a potential cause of health effects. Inaudible low-frequency noise and infrasound from IWTs cannot be ruled out as plausible causes of health effects.
