Project 26 will develop numerical models to evaluate the transmission of low frequency noise (LFN) through elastic panels such as windows, doors, walls and roofs. The models and simulations will be optimized for applicability to residential buildings in airport neighborhoods. The long-term goal is to develop appropriate models and metrics to assess and mitigate the indoor impact of outdoor-generated LFN.
The major outcome of Project 26 will be the development of simple models for estimating the transmission of LFN through single-pane and double-pane windows. The study will highlight and quantify the need for appropriate elastic mounting methods that optimize window noise-blocking performance. This will help window manufacturers and the building industry to establish criteria for classifying window acoustic performance.
The study also aims to provide consumers with necessary information for choosing windows with matched mounting supports as a means of minimizing the ingress of LFN.
Improved tools for assessing, modeling and predicting LFN propagation through windows under various mounting conditions. New criteria for acoustic performance classifications. Improved information for consumers who wish to select noise-blocking window materials and mounting hardware.
