The Hamburg (80 decibels) and Toronto (85 decibels) transit systems, both of which are "steel-on-steel," prove that proper design and maintenance can provide a pleasantly quiet system and, in fact, can be quieter than a rubber-tired system. The average levels in New York trains, by contrast, are between 95 and 100 decibels. Some of the techniques used successfully to reduce noise levels are sound-absorbing materials on ceilings and walls in stations; sound-absorbing concrete blocks between rails in stations; lubricated rails on curves; rubber suspensions on cars; damped and isolated car-body design; continuous welded rail; special wheels, either damped or resilient; and air springs.
