A dynamoelectric machine load package has an acoustically isolated enclosure for reducing the amount of structure-borne and air-borne vibration and noise reaching the surrounding environment. Bearing pedestals for supporting a rotating shaft of a rotating field winding of a dynamoelectric machine and a reduction gear for driving the rotating shaft are firmly mounted on a load package base which is firmly attached to a foundation. The enclosure and a stationary armature of the dynamoelectric machine are independently resiliently mounted on the load package base. The enclosure is free to vibrate independently of the load package so that vibrations are not directly transmitted from the load package to the enclosure and are not directly transmitted from the enclosure to the load package base. Acoustic damping material is applied to interior walls of the enclosure.
