摘要： A damper disc made of material having significant loss to vibration and low sound propagation velocity is arranged to be laid over a CD disc and in good contact with its upper surface to suppress and dissipate vibrational energy from the CD disc. The damper is also light opaque and light absorptive. Specific suitable materials are disclosed as well as an embodiment suitable for making the damper available as an after market accessory, and integral part of the CD player, or as an integral part of the CD disc.
