The purpose of this study was to determine the insertion loss of a traffic noise barrier erected along I-280 in Harrison, N.J. This barrier was constructed of a phenolic-impregnated paper honeycomb core faced with aluminum panels on both sides, a type not previously used in New Jersey. Noise data was recorded both before and after barrier construction, from several microphones placed at two locations at a site adjacent to the highway. Also recorded were traffic counts by type of vehicle for both eastbound and westbound traffic, and traffic speeds for westbound traffic only. For comparison purposes, small samples were randomly selected from the full-size samples and analyzed using the same method.
