The aim of this study was to investigate the effect of carbon nanotubes (CNTs) and foaming on sound transmission loss (STL) of wood fiber‐low density polyethylene composite. For this purpose, low density polyethylene, wood fiber, foaming agent, coupling agent and modified CNTs were mixed in an internal mixer to produce test samples. The standard circular samples were produced by using compression molding method in a hot press machine. Sound transmission loss was measured by an impedance tube. Results showed that the use of CNTs improved the foam morphology in the composites. Foaming and the use of CNTs improve the STL of composites (especially at medium and higher frequencies) and the highest STL was obtained for wood fiber/LDPE foamed composites containing 1% CNT. © 2017 Wiley Periodicals, Inc.
