Single mode 3Hz band and multiple modes in the 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 test installations are possible. The adoption rate for elevated road bridges is increasing. We clarify the causes of occurrence and respond to solutions from investigation, analysis, and prediction to appropriate measures, construction, installation, and effect confirmation. 【Features】 ■ Key to countermeasures against low-frequency noise and vibration from elevated road bridges ■ Increasing adoption rate for elevated road bridges ■ No traffic regulation required ■ Test installations are possible ■ Clarifies causes of occurrence and responds to solutions *For more details, please refer to the PDF materials or feel free to contact us.
