Comparison of Annoyance from Railway Noise and Railway Vibration. [PDF]
Int J Environ Res Public Health, 2017 The aim of this study is to compare vibration exposure to noise exposure from railway traffic in terms of equal annoyance, i.e., to determine when a certain noise level is equally annoying as a corresponding vibration velocity. Based on questionnaire data from the Train Vibration and Noise Effects (TVANE) research project from residential areas exposed

Synthesis of pass-by railway noise
The Journal of the Acoustical Society of America, 2008 Pass-by railway noise is one of the main problems in the community. Typically pass-by railway noise is estimated using Leq or Lden in dB(A) and often these methods do not reflect the listener perceptual overview. It is therefore necessary to reduce the pass-by railway noise by synthesizing the noise characters into various segments.

A New Design Method of Shield Tunnel Based on the Concept of Minimum Bending Moment
Applied Sciences, 2022 As the soil-resistance coefficient in a soft soil area is small, overlarge bending moment may cause exceeding transverse deformation for the shield tunnel and cause structural diseases and waterproof failure at the longitudinal segment joints.
