Sound Transmission Characteristics Through Multi-panel Structures of Wooden Doors and Uncertainty Components in the Measurements 

Conference paper
Part of the Lecture Notes in Mechanical Engineering book series (LNME)


This paper examines the sound transmission loss (STL) through composite panel door systems commonly used in the recording studios, operating theaters, libraries, interview rooms, offices, museums, etc. The sound insulation property of different combinations of door panel of materials such as wood/plywood, cement board, wool, tec sound, laminate is investigated. Reverberation chamber method is used to determine the sound transmission loss. This paper presents the results of a series of doors tests to estimate the sound transmission loss through different combinations of wooden door system. The main aim of this study is to design such a system using wooden door panels that can provide significant noise reduction. The other objective of this study is to evaluate typical doors characteristics including the effect of minor modifications that could increase the noise reduction provided by the door system.
