- Abstract
A total of 43 tests were made on a vibration shaker to measure the transfer properties of a blasting seismograph. The main elements of the full monitoring chain are modelled using second order transfer functions. The parameters of these functions are calibrated through nonlinear fits of the measured responses. The form of the overall resulting transfer function has been kept while its parameters have been changed to consider four additional seismographs; two of these devices have a transmissibility in compliance with ISEE specifications, while the other two are in line with DIN 45669:1:2010. Fifteen theoretical sinusoidal input functions are generated to analyze the influence of the phase response. They are run through the transfer function of each seismograph to assess the error (expressed as gain) in the peak velocity and investigate the performance of seismograph's standards.
