| description abstract | This paper investigates the physical mechanisms related to highway noise barrier insertion loss, and evaluates the accuracy of insertion loss of the existing traffic-noise model, TNM 2.5, compared to STAMINA 2.0 and field measurement data. To quantify the accuracy of either TNM or STAMINA, a new Highway Noise Prediction program, HNP 1.0, was developed. The findings of the study show that from the perspective of diffraction theories, STAMINA 2.0 and HNP 1.0 predict more accurate insertion loss than TNM 2.5 based on the measurement data, and TNM 2.5 over-predicts the insertion loss by approximately | |
