EXPERIMENTAL STUDIES ON SOUND INSULATION PROPERTIES OF TRADITIONAL WOODEN HOUSES

Experimental and Theoretical Analysis of Sound Absorption Properties of Finely Perforated Wooden Panels

Perforated wooden panels are typically utilized as a resonant sound absorbing material in indoor noise control. In this paper, the absorption properties of wooden panels perforated with tiny holes of 1-3 mm diameter were studied both experimentally and theoretically. The Maa-MPP (micro perforated panels) model and the Maa-Flex model were applied to predict the absorption regularities of finely ...

Investigation of Acoustic Properties of Polymer Nanocomposites regarding Combined Sound Absorption and Insulation Characteristics

Introduction: Nowadays multiple techniques have been developed to noise control. One the most important way is the control based on sound absorption and insulation. The purpose of current study was to improve the acoustic properties of soft polyurethane foam regarding combined sound absorption and insulation characteristics. Materials and Methods: Polyacrylonitrile and polyvinylidine fluoride ...

Climatic Compatibility of Courtyard Houses, Based on Shading- sunlit Index; Case Studies: Traditional Houses in Kashan & Ardabil Cities

Today, access to sustainable environment for more presence of humans in open space should improve the quality of open spaces and human thermal comfort. Hence, the courtyard as an open space is an important element in solar radiation absorption and providing thermal comfort. The aim of this paper is to investigate the climatic performance of traditional courtyard houses, according to shading ...

Traditional Houses with Stone Walls in Temperate Climates: The Impact of Various Insulation Strategies

Sound insulation issues

This paper gives an overview of three topics related to sound insulation in buildings. The first project included laboratory and field measurements of sound insulation against aircraft noise. As well as various technical papers, the project produced software to help in the design of adequate sound insulation. In a second project, re-analysis of survey results allowed the development of a ration...
