  abstract = {{T}he horizontal-to-vertical ({H}/{V}) method has the potential to significantly contribute to site effects evaluation, in particular in urban areas. {W}ithin the {E}uropean project, site effects assessment using ambient excitations ({SESAME}), we investigated the nature of ambient seismic noise in order to assess the reliability of this method. {T}hrough {ID} seismic noise modeling, we simulated ambient noise for a set of various horizontally stratified structures by computing efficiently the displacement and stress of dynamic {G}reen's functions for a viscoelastic-layered half-space. {W}e performed array analysis using the conventional semblance-based frequence-wavenumber method and the three-component modified spatial autocorrelation method on both vertical and horizontal components and estimated the contribution of different seismic waves (body/surface waves, {R}ayleigh/{L}ove waves) at the {H}/{V} peak frequency. {W}e show that the very common assumption that almost all the ambient noise energy would be carried by fundamental-mode {R}ayleigh waves is not justified. {T}he relative proportion of different wave types depends on site conditions, and especially on the impedance contrast. {F}or the {ID} horizontally layered structures presented here, the {H}/{V} peak frequency always provides a good estimate of the fundamental resonance frequency whatever the {FIN} peak origin ({R}ayleigh wave ellipticity, {A}iry phase of {L}ove waves, {S}-wave resonance). {W}e also infer that the relative proportion of {L}ove waves in ambient noise controls the amplitude of the {H}/{V} peak.},
