Expansion of urban transit within cities requires attention to the negative effects of noise and vibration on people, structures and equipment. Potential noise and vibration issues can be identified during the design phase through modelling. Detailed analysis of the sources of noise and vibration can be used to optimize track-forms for significant savings and benefits. During construction and post-construction, negative effects of noise and vibration can be mitigated at the source, the transmission path and/or the receptor.
Participants Will Learn
- Participants will learn about the types of noise including airborne, groundborne and structure-radiated noise.
- Participants will learn how to recognize the source of noise and vibration in above-ground and underground rail lines and how noise is measured.
- Participants will learn how predictive modelling is used to understand noise propagation and determine mitigation.
- Participants will be shown how a detailed analysis of noise and vibration can be used to optimize track design.
