Assessment of Sound Insulation Treatments

  Project Data
Funds: $350,000
Research Agency: Wyle Laboratories, Inc
Principal Investigator: Ben H. Sharp

Completion Date: 9/15/2014

Sound insulation programs have been in existence since the 1980s. They have been successful in improving the quality of life for homeowners and building occupants by reducing aircraft noise levels in those structures. The last 20-30 years has brought on significant improvements in sound insulation materials, treatments, methods, techniques, and lessons learned. In addition, with the passage of time there is a perception by some property owners that those structures that were sound insulated in the early programs are not performing as they once did. There has not been a programmatic approach to evaluate the long-term effectiveness of sound insulation programs including design criteria, materials, and installation standards. As such, research is needed in this area.
The objectives of this research are to (1) evaluate the degree and causes of deterioration, if any, in the acoustic performance of homes and buildings that were sound insulated during early sound insulation programs and (2) provide guidance to help airports determine the expectation of the durability and attenuation performance of currently available sound insulation techniques, treatment, and materials that are available today. This research should address, at a minimum, design, installation, materials, and treatments associated with sound insulation programs.
STATUS: This has been published as ACRP Report 105:  Guidelines for Ensuring Longevity in Airport Sound Insulation Programs.  The Contractor's Final Report can also be viewed.
