Synopsis:

Increased national and international travel over the last decades has caused an increase in the global number of passengers using different means of transportation. Great effort is being directed to improving the noisy environment in the residential community. There is also a strong competition between different manufacturers to make their products quieter. Many recent studies on noise reduction involve the use of perforated plates in the air and gas flow ducting connected to the engine. This book deals with the modeling of perforates as an absorbent. Liners have to be carefully tailored in order to achieve the most efficient attenuation. This book fills some gaps in the impedance modeling of perforated liners. It also concentrates on those complicated situations of sound propagation in ducts that were solved earlier using Finite Element Methods. Alternate analytical solutions to these problems are developed here, which gives more physical insight into the results.
