Acoustic Performance of Resilient Materials Using Acrylic Polymer Emulsion Resin

There have been frequent cases of civil complaints and disputes in relation to floor impact noises over the years. To solve these issues, a substantial amount of sound resilient material is installed between the concrete slab and the foamed concrete during construction. A new place-type resilient ma...
