Noise modeling of short safety barriers in FHWA's updated Traffic Noise Model (TNM) version 3.1

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023
Solid safety barriers are commonly constructed along highways. These barriers improve highway safety by preventing collisions and providing separation from slopes or adjacent hazards such as deep water. For elevated and at-grade roadways, shorter barriers have also been shown to noticeably reduce traffic noise. In prior research, modeling methods were

Comparative evaluation of the ground reflection algorithm in FHWA Traffic Noise Model (TNM 2.5)

Applied Acoustics, 2007
Abstract This paper investigates the algorithm of ground reflection regarding highway noise propagation, and evaluates the accuracy of predicted absolute noise levels without barriers of FHWA TNM 2.5. To achieve this purpose, new highway noise prediction program, Highway Noise Predictor (HNP 1.0) with the improved ground reflection algorithm, is ...
