he Noise Control Project along the Jakarta-Bandung High-Speed Railway (JBHSR) line aims to manage noise levels effectively. JBHSR is a high-speed railway connecting Jakarta and Bandung in Indonesia. It’s the first high-speed railway constructed outside China using Chinese standards and technology, with a speed of 350 kilometers per hour. It’s a landmark project of the Belt and Road Initiative and a strategic project for Indonesia. Construction began in June 2018, and the railway commenced operation on September 7, 2023.

Noise-sensitive areas along the JBHSR line are equipped with railway sound barriers. Bridge sound barriers have heights of 2.3 meters and 3.3 meters, with the upper 1 meter of the 3.3-meter barriers made of transparent soundproof panels. Embankment sound barriers come in heights of 3.05 meters and 4.05 meters, with the upper 1 meter of the 4.05-meter barriers consisting of transparent soundproof panels. Once constructed, these barriers reduce noise levels by over 30 decibels with a noise reduction coefficient of over 0.7. Implementing these barriers has improved the noise environment quality along the JBHSR line and near stations, meeting railway noise emission standards.

Throughout the project’s supply guarantee process, our company demonstrated scientific management, meticulous organization, prompt action, effective support, and patient and meticulous service. Overcoming numerous difficulties, we completed tasks such as production, supply, and installation, ensuring the smooth operation of JBHSR. Our company’s professionalism, technical competence, and service attitude in the JBHSR project earned appreciation and commendation from China Railway International Co., Ltd.
