A prosthetic support, comprising: a structure configured to apply a clamping force to a head of a recipient while extending about a back of at least one of a head or neck of the recipient, wherein the clamping force is sufficient to hold at least a portion of a bone conduction device supported by the structure in proximity to the head of the recipient such that output generated by the bone conduction device supported by the structure is directed into skin of the recipient at a location behind an ear canal of the recipient on the mastoid bone of the recipient, wherein the output includes vibrations; an attachment portion attached to or being a part of the structure, wherein the attachment portion is configured to removably attach the bone conduction device to the prosthetic support, a skin interface portion that is integrated with the attachment portion, the skin interface portion being located on the prosthetic support such that the skin interface portion abuts skin of the recipient at the location behind the ear of the recipient at the location on the mastoid bone of the recipient when the clamping force is applied to the head of the recipient; and wherein the skin interface portion is configured to transcutaneously transmit the vibrations of the bone conduction device into the skin of the recipient, from which the vibrations enter the mastoid bone of the recipient, in amounts to provoke a hearing percept in the recipient, the vibrations traveling through the skin interface portion; characterized by a support portion configured to vibrationally isolate the skin interface portion from the remainder of the support. a structure configured to apply a clamping force to a head of a recipient while extending about a back of at least one of a head or neck of the recipient, wherein the clamping force is sufficient to hold at least a portion of a bone conduction device supported by the structure in proximity to the head of the recipient such that output generated by the bone conduction device supported by the structure is directed into skin of the recipient at a location behind an ear canal of the recipient on the mastoid bone of the recipient, wherein the output includes vibrations; an attachment portion attached to or being a part of the structure, wherein the attachment portion is configured to removably attach the bone conduction device to the prosthetic support, a skin interface portion that is integrated with the attachment portion, the skin interface portion being located on the prosthetic support such that the skin interface portion abuts skin of the recipient at the location behind the ear of the recipient at the location on the mastoid bone of the recipient when the clamping force is applied to the head of the recipient; and wherein the skin interface portion is configured to transcutaneously transmit the vibrations of the bone conduction device into the skin of the recipient, from which the vibrations enter the mastoid bone of the recipient, in amounts to provoke a hearing percept in the recipient, the vibrations traveling through the skin interface portion; characterized by a support portion configured to vibrationally isolate the skin interface portion from the remainder of the support.
