In an aspect, a system is provided for reducing torsional vibrations for an engine having a crankshaft. The system includes an isolation device, which includes a shaft adapter that is mounted to the crankshaft, a pulley that is rotatably mounted to the shaft adapter, and at least one isolation spring that resiliently transfers torque between the pulley and the shaft adapter. The system further includes a torsional vibration damper that is mountable to the crankshaft. A noise generation space extends axially between the isolation device and the torsional vibration damper. The system further includes a noise abatement ring that extends axially from one of the isolation device and the torsional vibration damper towards the other of the isolation device and the torsional vibration damper, and at least partially radially encloses at least a portion of the noise generation space.
