User's Instructions for SOUND32 (Caltrans Version of FHWA Highway Noise Prediction and Barrier Cost Reduction Procedure, STAMINA 2.0/OPTIMA)

摘要

This report is the user's manual for the computer program SOUND32. SOUND32 is the Caltrans version of the FHWA highway noise prediction and barrier cost reduction (BCR) procedure programs. SOUND32 allows for the prediction of highway traffic noise for complex geometric sites and allows the user to examine the effectiveness and cost of many different barrier heights more quickly than in the past. This allows the designer to more easily develop an optimum barrier design. SOUND32 includes calculations for barrier effectiveness and cost information for each noise barrier at several heights. The user selects a set of barrier heights and is given the noise level at each receiver and the total cost of the barrier system. Based on these results the user can change barrier heights to improve (optimize) the cost efficiency of the barrier system.
