Noise from Traffic and Noise Barrier Performance: A Prediction Technique

摘要

A procedure for predicting Army vehicle noise and barrier performance is described. This procedure is faster and simpler than existing methods because the calculations deal with pasques--linear quantities--rather than decibels. The equations provided for direct calculation can be programmed on small computers for rapid solution, eliminating the table lookups required with decibels. The new procedure can handle more complex sites, yet also enables quick assessment of a situation. This limits the unnecessary calculations by screening out sites not really in need of noise reduction. In addition, the procedure can predict noise for more vehicle types, including Army tracked vehicles for transporting personnel and weapons. (Author)
