Noise from unmanned aerial vehicles, commonly referred to as "drones," will likely shape our acoustic environment in the near future. Yet, reactions of the population to this new noise source are still little explored.

Transportation noise composoed of identifiable noise events
Noise Control Engineering Journal, 2015Transportation noise consists of noise events, which come from moving aircrafts, trains, ships, boats and road vehicles. The noise of an isolated sound event is assessed by short term measurement of the sound exposure level, LAE. On the other hand, much legislation and many regulations and guidelines employ the day and the night average sound level ...

Transportation Noise—Airplane Noise Reduction
The Journal of the Acoustical Society of America, 1973Current Federal noise regulations will be discussed along with their impact on community noise exposure. Brief references will be made to specific technical areas where significant advances in noise reduction have been made and to noise reduction goals for the future.

Annalen der Physik, 1995
AbstractWe study the overdamped motion of a particle in a one‐dimensional periodic potential driven by a stochastic force. If the stochastic force is correlated in time (non‐white), and if the potential has no inversion symmetry, a current is generated. In the case of a piecewise linear potential we obtain a closed expression for the current as a ratio

SAE transportation noise activities
The Journal of the Acoustical Society of America, 2000The SAE Vehicle Sound Level Form Committee continues to ensure the SAE road vehicle standards are maintained. Currently, there is a trend to move to internationally recognized standards that are technically valid procedures for rating the various products or subsystems.

BACKGROUND Cardiovascular effects of environmental noise are a growing concern. However, the evidence remains largely limited to the association between road traffic noise and hypertension and coronary heart diseases.

Noise-Induced Transport with Low Randomness
Physical Review Letters, 2002We study the transport of overdamped Brownian particles in periodic potentials subject to a spatially modulated Gaussian white noise. We derive an analytical expression for the diffusion coefficient of particles. By means of velocity, diffusion coefficient, and their ratio (Péclet number) we discuss (a) symmetric potential and modulation of noise ...

Exposure-response relationships for transportation noise
The Journal of the Acoustical Society of America, 1998This article presents synthesis curves for the relationship between DNL and percentage highly annoyed for three transportation noise sources. The results are based on all 21 datasets examined by Schultz [J. Acoust. Soc. Am. 64, 377–405 (1978)] and Fidell et al. [J. Acoust. Soc. Am.

Community Noise—Surface Transportation
The Journal of the Acoustical Society of America, 1973Noise due to surface transportation is still rising, but there is evidence that it is leveling off. The important change in the last five years has been the increase in knowledge of the relative importance of the noises from exhaust, intake, engine radiation, tires, and airflow and the extent to which they can be modified at reasonable cost. Trucks and

Transportation noise and incidence of hypertension
International Journal of Hygiene and Environmental Health, 2018The evidence on exposure to transportation noise and development of hypertension is inconclusive, mostly because of a lack of high quality studies of longitudinal design.This cohort study aimed at investigating the association between exposure to road traffic, railway or aircraft noise and incidence of hypertension.
