Measurement of elastic soil properties using transient dynamic movements (i.e. waves) is widespread both in the field and the laboratory. The wave model employed for the inversion problem must be simple, but representative of the measurement system. Data analysis and manipulation should facilitate the inversion procedure. Time and frequency domain approaches have both been employed for this purpose, but both face some limitations. Simultaneous time-frequency representations offer a tool to enhance data analysis. Wavelet transforms are a very successful method currently employed to obtain such representations. Here this method is applied to examine traces from laboratory pulse tests, both experimental and simulated.
