Acoustical Materials: Solving the Challenge of Vehicle Noise

2021-08-11

Journal of the Acoustical Society of America Book Review INCE/NCEJ Book Review What is acoustics? What is noise? How is sound measured? How can the vehicle noise be reduced using sound package treatments? Pranab Saha answers these and more in Acoustical Materials. Acoustics is the science of sound, including its generation, propagation, and effect. Although the propulsion sources of internal combustion engine (ICE) vehicles and electric motor-powered vehicles (EV) are different and therefore their propulsion noises are different, both types of vehicles have shared noise concerns: Tire and road noise Wind noise Vehicle noise and vibration issues have been there almost from the inception of vehicle manufacturing. The noise problem in a vehicle is very severe and is difficult to solve only by modifying the sources of noise and vibration. Sound package treatments address the noise and vibration issues along the path to reduce in-cabin noise.

Thermal Management in Automotive Applications

2015-03-30

With new and more stringent standards addressing emission reduction and fuel economy, the importance of a well-developed engine thermal management system becomes even greater. With about 30% of the fuel intake energy dissipated through the cooling system and another 30% through the exhaust system, it is to be expected that serious research has been dedicated to this field. Thermal Management in Automotive Applications, edited by Dr. T. Yomi Obidi, brings together a focused collection of SAE technical papers on the subject. It offers insights into how thermal management impacts the efficiency of engines in heavy vehicles, the effects of better coolant flow control, and the use of smart thermostat and next-generation cooling pumps. It also provides an in-depth analysis of the possible gains in optimum warm-up sequence and thermal management on a small gasoline engine.

Technology for a Quieter America

2010-01-01

Exposure to noise at home, at work, while traveling, and during leisure activities is a fact of life for all Americans. As the population of the United States and, indeed, the world increases and developing countries become more industrialized, problems of noise are likely to become more pervasive and lower the quality of life for everyone. Efforts to manage noise exposures, to design quieter buildings, products, equipment, and transportation vehicles, and to provide a regulatory environment that facilitates adequate, cost-effective, sustainable noise controls require our immediate attention. This book, written for the engineering community; the public; government at the federal, state, and local levels; private industry; labor unions; and nonprofit organizations, looks at the most commonly identified sources of noise, how they are characterized, and efforts that have been made to reduce noise emissions and experiences.

The Ford GT

2004-03-08

In the 1960's very little science and engineering had been applied to the art of motor racing. As a result, there was no general agreement about the best technical approach to generating speed on a road racing track. Each car maker viewed the problem through the lenses of their own history and capabilities. The cars on the starting grid demonstrated how varied these histories were. When Ford first assaulted Le Mans in 1964, the company followed a similarly casual approach by initially purchasing a race car design from the English firm Lola. This car's numerous shortcomings soon led Ford to apply its considerable engineering and developmental resources to the project, and the result was the one-two-three finish in 1966. First place finishes followed in 1967, 1968 and 1969. It is the fabulous victories by Ford in the 1960's that inspired the new 2005 Ford GT. Based on a concept car the new production car embodies the characteristic proportions and styling elements of the original GT.
