get_PSD_dB# PowerSpectralDensity.get_PSD_dB(ref_value=1.0)# Get the PSD in dB/Hz, as a Field. Parameters: ref_valuefloat, default: 1.0Reference value for dB level calculation, by default 1.0. Example: ref_value = 2e-5 Pa for sound pressure level (dBSPL/Hz). Returns: FieldField containing the PSD in dB/Hz, and associated frequencies in Hz. Return type: Field
