WebApr 10, 2024 · Road traffic noise is a special kind of high amplitude noise in seismic or acoustic data acquisition around a road network. It is a mixture of several surface waves with different dispersion and harmonic waves. Road traffic noise is mainly generated by passing vehicles on a road. The geophones near the road will record the noise while … WebAs seismic waves travel, they cause an adiabatic pressure perturbation, which causes a temperature change and, potentially, freezing and melting. These cause thermal and compositional diffusion and result in attenuation. Loper and Fearn (1983) derived an expression for frequency-dependent attenuation due to diffusion.
