Details on the Time and Frequency Domain Data Properties

The Signal Processing Tool provides various methods to compute time and frequency domain data properties of signals.

Power Spectral Density (PSD)

The method get_power_density() computes the Power Spectral Density of a signal. The PSD provides insight in the power distribution across the frequencies of the signal.

frequency_domain_data.get_power_density()

Energy Spectral Density (ESD)

The method get_energy_density() computes the Energy Spectral Density of a signal. The ESD provides insight in the power distribution across the frequencies of the signal.

frequency_domain_data.get_energy_density()

SBR-B RMS Calculation

The method perform_sbr_b_rms() calculates SBR-B Root Mean Square (RMS) values from time-domain vibration data, following the Dutch SBR-B guideline for assessing nuisance in buildings. More information on the SBR guideline can be found here.

sbr_b_rms_values = time_domain_data.perform_sbr_b_rms()

The SBR-B provides limit values against which the calculated RMS values can be compared to assess the structure vibrations.
