[ We claim:] [1.]1. A protective apparatus for use in a compacting vehicle having an operator station, at least one roller drum and a vibratory mechanism mounted within the drum, the apparatus comprising:a substantially rigid protective member connectable with the vehicle so as to be disposed generally above the operator station, the protective member having a plurality of apertures configured to allow sound waves from vibrations of the vehicle, including low frequency sound waves generated by operation of the vibratory mechanism, to propagate through the protective member while generally preventing solid objects from falling through the protective member, each of the plurality of apertures having an inner diameter within the range of from about 1.8 millimeters to about 25.4 millimeters.
