Abstract
This paper presents the development of a coupled finite element - boundary element model of rolling noise from a resilient light rail wheel on several types of tracks. The vibro-acoustic model utilizes a 3D elastic solid representation for both wheel and rail which are excited by linearized
Hertzian interface loads. Estimates of the radiated sound power, radiation efficiencies and wayside noise levels are obtained and then scaled using a parallel impedance framework and a roughness profile. Results are compared to recently measured vehicle passby noise and track decay rates at
Sound Transit in Seattle Washington.

期刊介绍：
Noise and Health is the only International Journal devoted to research on all aspects of noise and its effects on human health. An inter-disciplinary journal for all professions concerned with auditory and non-auditory effects of occupational, environmental, and leisure noise. It aims to provide a forum for presentation of novel research material on a broad range of topics associated with noise pollution, its control and its detrimental effects on hearing and health. It will cover issues from basic experimental science through clinical evaluation and management, technical aspects of noise reduction systems and solutions to environmental issues relating to social and public health policy.
