Abstract (en)
[origin: CA3112832A1] The device for preventing sound transmission through a spacer tube, an aperture or a duct (1) can be realized by inserting a damping body (21) which can be cost-effectively mass-produced and can be inserted through the apertures in the wall (15) without any effort and with correspondingly low cost. There is no need for laborious plugging with rock wool or liquid mortar.
