Overview of automotive noise and vibration
TLDR
An overview of automotive NVH engineering can be found in this paper, where the authors classify the interior noise into powertrain-related NVH, road-and tyre-relatedNVH, and wind-related NEH.Abstract:
Vehicle noise, vibration and harshness (NVH) is an important vehicle attribute. It is usually among the top five attributes in terms of its priority in the design of any vehicle type. Like other attributes of safety, performance, dynamics and fuel economy, this attribute has to be considered closely in the design process. This manuscript presents an overview of automotive NVH engineering. It classifies the interior noise into powertrain-related NVH, road- and tyre-related NVH and wind-related NVH. This paper also discusses brake- and chassis-related NVH, squeak and rattle and electromechanical-related NVH. In addition, the paper addresses exterior NVH, frequently described as drive-by NVH. The phenomenon is divided into usual or expected NVH and unusual or unexpected NVH. The paper provides a review of some of the recent literature in the field of automotive NVH.read more

Road traffic noise and hypertension.
TL;DR: The strongest association between exposure to traffic noise and hypertension was found among those with the least expected misclassification of true individual exposure, as indicated by not having triple-glazed windows, living in an old house and having the bedroom window facing a street.

TL;DR: In this paper, the authors examined exposure-effect relations between aircraft and road traffic noise exposure and reading comprehension and found that exposure at home was highly correlated with aircraft noise exposure at school and demonstrated a similar linear association with impaired reading comprehension.
