Single mode 3Hz band and multiple mode tens of Hz band! Measures against low-frequency noise caused by vibrations of elevated road bridges.
The "mD Series" is a vibration control device installed on elevated road bridges, which serves as a source of vibration, to reduce low-frequency noise and vibration impacts on nearby buildings. Traffic regulation is not required, and trial construction is possible. The adoption record for elevated road bridges is increasing. We clarify the causes of occurrence and respond to solutions from investigation, analysis, and prediction to suitable measures, construction, installation, and effect confirmation. 【Features】 ■ Key solution for low-frequency noise and vibration measures from elevated road bridges ■ Increasing adoption record for elevated road bridges ■ No traffic regulation required ■ Trial construction is possible ■ Clarifying the causes of occurrence and responding to solutions *For more details, please refer to the PDF materials or feel free to contact us.
