    摘要: An escalator step (12) includes a sound barrier material (40) covering over at least a portion of an inner surface (42) of a tread portion(30) and an inner surface (44) of a rise portion (32). In one example, the sound barrier material (40) comprises a sheet of vinyl. The sound barrier material (40) reduces noise radiation from the step (12) toward a cavity (26) within a passenger conveyor support structure (20) and reduces noise emanations from the cavity (26) through the steps (12). Several embodiments for securing the sound barrier material (40) in place are disclosed.
