Best Practices for Effective Sound Insulation


Airports have spent millions of dollars on sound insulation programs to mitigate aircraft noise in surrounding communities. While this is often a popular program in communities, it does not necessarily "solve" noise problems. An assessment of the effectiveness of sound insulation in different types of structures and their associated uses is necessary to understand where this solution can have the greatest impact and benefit to the community. Further, an assessment of sound insulation on a geographic level to identify whether or not certain methods of reducing indoor noise levels are more effective in different climates. Understanding the most effective ways to use sound insulation on a structural and geographic level will allow airports to better allocate funding and develop their noise strategy with a more targeted and effective approach.


The objective of this research is to assess how effective sound insulation is at reducing indoor noise levels in terms of structural differences, as well as in the context of different geographic locations and changing climates.
