Abstract
A generally tubular laminated acoustic damping pipe cover to be used on a water pipe to reduce the noise level of the pipe, having a sound insulation layer whose area density is 1.5-5.0 kg/m2 and a sound absorptive layer whose thickness is 4.0-10.0 mm, covered with a heat-contractile film which when heat treated will tighten the acoustic damping pipe cover on the water pipe but hold the pipe cover in a sliding fashion. The acoustic damping pipe cover is lightweight and easy to manipulate, and provides an excellent acoustic damping performance.
