The invention relates to a vibratory pile-driving apparatus having a carrier implement with a mast, on which, for the purpose of generating vibrations, a vibration generator with a transmission housing is supported, in which at least one pair of rotatably supported unbalanced units is arranged that are driven in a rotating manner by at least one rotary drive. According to the invention provision is made in that the transmission housing is surrounded by a soundproof housing, in which the transmission housing is supported by way of damping elements, and in that from the transmission housing at least one oil supply line and one oil discharge line are led out of the soundproof housing, wherein transmission oil can be cooled outside the soundproof housing.
