Recent advancements in the wind turbine technology, combined with available federal and state incentives, have greatly enhanced the development of wind powered electric generation facilities in the Eastern United States. Particularly ridges of the Allegany Mountains in New York, Pennsylvania, Maryland, West Virginia, and Virginia have become attractive sites for commercial wind farm developers....

An aircraft system noise study is presented for the Blended-Wing-Body (BWB) aircraft concept with three open rotor engines mounted on the upper surface of the airframe. It is shown that for such an aircraft, the cumulative Effective Perceived Noise Level (EPNL) is about 24 dB below the current aircraft noise regulations of Stage 4. While this makes the design acoustically viable in meeting the ...

Introduction Noise pollution has become an important problem in our society. Noise assessment regulations require the measurement and evaluation of noise. The basic equipment for this measurement is the noise monitoring systems (or NMS). The current generation of NMS consists of "dumb" systems that record noise level and, possibly, noise spectra, over programmed periods of time. The interpretat...

Noise pollution caused by transportation has become problem for societies with increasing traffic volumes and the development of cities day day. In European countries Turkey, transportation-related noise health problems as well reducing living standards people. It is necessary to carry out detailed studies in order determine pollution, especially regions where industry labor force are concentra...

have a sleeping berth behind the driver’s seat so the person can rest at travel centers during these federally mandated driver restorativesleep periods. Driver and public motor safety is the primary concern influencing HOS regulation. Understanding the factors that may contribute to commercial vehicle operator health and performance are important for guiding future regulations. Currently, occup...

Guidelines and regulations for the siting of industrial wind turbines (IWT) close to human habitation are generally predicated on the need to protect the sleep of the residents. ssumptions that IWT noise can be regarded as similar to other forms of environmental noise (traffic, rail and aircraft) and is masked by ambient noise. There has been no independent verification that these assumptions a...

BACKGROUND It can hardly be disputed that a school environment should be conducive or, at the very least, not prohibitive to effective learning. The provision of fair, equal and barrier-free access to education is referred to as inclusive education. South Africa supports a policy of inclusive schooling, striving to accommodate all children, including those with disabilities, in mainstream schoo...
