Acoustic Effect of Platform Screen Doors: A Case Study of IMES Metro Station, Istanbul

This case study demonstrates how Platform Screen Doors (PSDs) at IMES Station significantly improved the acoustic environment by providing both safety and effective noise isolation, reducing reverberation and enhancing speech intelligibility. The findings show that integrating PSDs enables compliant, cost-efficient acoustic design by lowering noise transmission and minimizing the need for extensive additional treatments.

Modeling the Effect of Railpad Stiffness on Railway Ground-Borne Vibration Levels

This study develops a theoretical model to assess how railpad stiffness affects ground-borne vibrations under varying train speeds and axle loads, highlighting its critical role in vibration transmission. It finds that while soft pads reduce high-frequency vibration and stiff pads limit deflection but increase transmission, an optimal intermediate stiffness provides the best balance between vibration control and structural performance.

Correlation of Traffic Noise Parameters in Queensland

The current available approaches for predicting road traffic noise level indicators rely solely on Linear Regression models that use either LA10(18H) or LA10(1H) as an input variable. This paper extends the prediction scope of regression models to include important indicators and additional road traffic factors as input variables and compares the performance of several machine learning regression methods.

Development of a venting management procedure for container fumigation operations

Container fumigation is frequently undertaken for quarantine and pre-shipment purposes. The process ensures that a commodity is free from pest and disease prior to export or import. Due to the hazardous nature of the chemicals used (such as methyl bromide and phosphine), physical air emission controls such as carbon filtration are required to minimise air quality impacts.

Health risk assessment methodology and environmental justice analysis using HHRAP

This study examines the utility of one HHRA methodology, the U.S. EPA Human Health Risk Assessment Protocol (HHRAP). It builds on a previous paper which evaluated the HARP risk assessment tool for similar purposes. HHRAP was developed by U.S. EPA to provide a means of simulating the risk caused by multi-pathway (air, soil, water, food, etc.) exposure to more than 200 air pollutants.
