Aeroacoustic sources of high speed maglev trains [PDF]

The Journal of the Acoustical Society of America, 1994
Noise has been identified as a potential source of concern associated with the introduction of high speed maglev trains into the existing transportation system in the United States. The first operational maglev systems have been shown to generate high noise levels at high speeds, with noise levels over 100 dBA at 25 m typical for the maximum cruising ...
