Abstract


Sound pollution in buildings is one of problems that need to be addressed for high-rise buildings in Thailand. In present, most high-rise buildings are constructed with flat and dense precast concrete panel systems which can cause high reflection of sound and also, the use of thin walls allows sound to transmit from outside to inside and in between the rooms. This study aims to develop composite concrete panels with better sound insulation using viscoelastic polymer film. The viscoelastic polymer film is a material known to have high damping property, and good ability to absorb and dissipates vibrations. It is expected that by installing VPF material in concrete panel, the vibration induced by sound can be reduced and which may lead to an improvement in sound properties. The results showed in this paper are preliminary results consisted of the measurement of vibration of concrete panel attached with VPF at different patterns and other basic properties such as compressive strength, density and water absorption.
