Sound insulation issues

چکیده
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 rational basis for sound insulation goals for walls between adjacent homes. In the third part of this paper the need for new research to develop improved methods of rating impact sound insulation is discussed.

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 ...
متن کاملHow much protection do the sound insulation standards give and is this enough?
Social surveys in several European countries have shown that inhabitants of multifamily dwellings are considerably annoyed by noise from their neighbour's activities. This is also in countries where sound insulation minimum requirements exist and have been enforced for many years. It is therefore necessary to establish data on the sound levels of activities in residential buildings and undertak...
متن کاملLong-Term Structural Behavior of Resilient Materials for Reduction of Floor Impact Sound
People’s tendency towards living in apartment houses is increasing in a densely populated country. However, some residents living in apartment houses are bothered by noise coming from the houses above. In order to reduce noise pollution, the communities are increasingly imposing a bylaw, including the limitation of floor impact sound, minimum thickness of floors, and floor soundproofing solutio...
متن کاملAcoustic metamaterials capable of both sound insulation and energy harvesting
Membrane-type acoustic metamaterials are well known for low-frequency sound insulation. In this work, by introducing a flexible piezoelectric patch, we propose sound-insulation metamaterials with the ability of energy harvesting from sound waves. The dual functionality of the metamaterial device has been verified by experimental results, which show an over 20 dB sound transmission loss and a ma...
