Acoustics and the Quiet Train Ride
William A. Jack · Transactions of the American Institute of Electrical Engineers · 1942
This paper discusses those fundamentals of acoustics which are important in attacking practical problems in noise reductoin. A description is given of the instruments suitable for measuring the physical quantities involved. The train problem is analyzed, and data taken by the author on a relatively quiet type of coach are presented. The various methods of noise control which may be applied to a coach are discussed, and data are presented indicating the possibilities of each method.
