Noise Reduction Techniques in Electrical Systems Kellermann, Erlangen, Noise in Receiving Systems Electronic Noise and Fluctuations in Solids This book is devoted to the physics of electronic fluctuations noise in solids, and covers almost all important examp Agrawal Volume 41 For Your name.
Close Send. Few engineers seem to understand the action of screened cables, especially, and chapter 2 gives an excellent introduction. Couldn't put it down. Instead, I got much, much more. I was able to read it cover to cover in a weekend without getting bored from too much detail, and it had many many real measurements of noise in systems that made the information much more quantitative.
For instance, instead of saying "in order to get the most noise reduction, you need to use a shielded cable only grounded on one end", he says "a shielded cable grounded on one end has 84dB of attenuation to magnetic noise and much more for electric, while if the shield is grounded at both ends the attenuation is more like 36dB". Those numbers are critical if you're trying to balance signal quality with cost.
One of the best textbooks I've ever purchased. Noise Reduction Techniques By Mr. Leslie O. The topic is the shield cut-off frequency of a coaxial cable. Common-mode currents at low frequencies below a few hundred hertz cause noise problems with coaxial cables, but signals above tens of kilohertz do not.
This is vital data which is apparently not explained in many text books. For me, this topic justifies the cost of the text. Having said that, I am annoyed because the book is quite expensive relative to other books of its size and age. This policy represents a clear challenge for the next few decades not only for European railway companies: the considerable increase in mobility will lead to a doubling of the railway traffic volume within the next 10 to 20 years.
To reduce the environmental impact, the Directive on the Assessment and M- agement of Environmental Noise has been put into force in Europe, aiming at avo- ing, preventing or reducing harmful effects of environmental noise on human health.
Aircraft noise has adverse impacts on passengers, airport staff and people living near airports, it thus limits the capacity of regional and international airports throughout the world.
Reducing perceived noise of aircraft involves reduction of noise at source, along the propagation path and at the receiver. Effective noise control demands highly s. Is noise the most neglected green issue of our age?
This book argues compellingly that it is, and tells you all you need to know about noise as a social, cultural, environmental and health issue. Across the world, more people are disturbed by noise in their day-today lives than by any other pollutant on Earth. From the shanty towns of Mumbai to the smart boulevards of Paris, noise is a problem.
It is damaging people's health, costing billions, and threatening the world's natural sound systems in the same way that climate change is altering its eco-systems. Drawing on evidence from all over the world, this book showcases policies and strategies that have worked to decrease noise pollution, and offers lessons for policymakers and environmental health professionals, campaigners and any individual affected by noise.
Written by a renowned noise campaigner and experts in law and health, this book tells you all you need to know about noise as a social, cultural and environmental issue and how we can act to build a more peaceful world. Author : Jens C. The event, which was jointly organized by the Competence Centre Chalmers Railway Mechanics CHARMEC and the Departments of Applied Mechanics and Applied Acoustics at Chalmers University of Technology in Gothenburg, Sweden, covered a broad range of topics in the field of railway noise and vibration, including: prospects, legal regulations and perceptions; wheel and rail noise; prediction, measurements and monitoring; ground-borne vibration; squeal noise and structure-borne noise; and aerodynamic noise generated by high-speed trains.
Further topics included: resilient track forms; grinding, corrugation and roughness; and interior noise and sound barriers. This book, which consists of a collection of peer-reviewed papers originally submitted to the workshop, not only provides readers with an overview of the latest developments in the field, but also offers scientists and engineers essential support in their daily efforts to identify, understand and solve a number of problems related to railway noise and vibration, and to achieve their ultimate goal of reducing the environmental impact of railway systems.
Author : Scott D. By providing all the basic knowledge needed to assess how useful active noise control will be for a given problem, this book assists in the designing, setting up, and tuning of an active noise-control system.
Written for students who have no prior knowledge of acoustics, signal processing, or noise control but who do have a reasonable grasp of basic physics and mathematics, the text is short and descriptive, leaving all mathematical details and proofs concerning vibrations, signal processing and the like to more advanced texts or research monographs.
The book can thus be used in independent study, in a classroom with laboratories, or in conjunction with a kit for experiment or demonstration. Topics covered include basic acoustics, human perception and sound, sound intensity and related concepts, fundamentals of passive noise- control strategies, basics of digital systems and adaptive controllers, and active noise control systems.
Presents Evidence-Based Guidance on Noise Abatement Methods Solutions for reducing the noise impact of road and rail traffic can be found in the use of natural elements in combination with artificial elements in urban and rural environments.
Ground and road surface treatments; trees, forests, and tall vegetation; and the greening of buildings and other surfaces can contribute to powerful and cost-effective noise reduction. This project involved experts from seven countries, and assessed noise reduction in terms of sound level reductions, perceptual effects, and cost—benefit analysis.
It considered a number of green abatement strategies, and aimed to develop a toolbox for reducing road and rail traffic noise in outdoor environments. Combines Theory with Practice Broad in both theory and application and based on leading-edge research, the book brings together the findings and their practical use.
