In the laboratory study, the annoyance caused by the passby sounds from a magnetic levitation (maglev) train was investigated. The listeners were presented with various sound fragments. The task of the listeners was to respond after each presentation to the question: "How annoying would you find the sound in the preceding period if you were exposed to it at home on a regular basis?" The independent variations were a) the driving speed of the maglev train (varying from 100 to 400 km/h), b) the outdoor A weighted sound exposure level (ASEL) of the passbys (varying from 65 to 90 dB), and c) the simulated outdoor to indoor reduction in sound level (windows open or windows closed). As references to the passby sounds from the maglev train (type Transrapid 08), sounds from road traffic (passenger cars and trucks) and more conventional railway (intercity trains) were included for rating too. Four important results were obtained. Provided that the outdoor ASEL's were the same, 1) the annoyance was independent of the driving speed of he maglev train was considerably higher than that caused by the intercity train, 3) the annoyance caused by the maglev train was hardly different from that caused by road traffic, and 4) the results 1) – 3) held the true both for open or closed windows. On the basis of the present results, it might be expected that the sounds are equally annoying if the ASELs of the maglev-train passbys are at least 5 dB lower than those of the intercity train passbys. Consequently, the results of the present experiment do not support application of a railway bonus to the maglev-train sounds.
