CONVERT CURVES TO PRESSURE DB RMS¶
Combines two input curves (X-values and Y-values) into a cross-plotted curve, then converts the result to a pressure level expressed in dB RMS (root-mean-square decibels). Use this worker when you need to transform raw pressure time-history or spectral data into a dB RMS pressure representation for NVH or acoustic post-processing.
When to use¶
Classification: process.
Tagged: acoustics, cross_plot, curve_transform, db_rms, decibel, nvh, pressure, rms.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve With X-Values | curve_x | vector | — | X-axis values of the source curve (e.g., frequency in Hz or time in seconds); if a CurveGroup is supplied, only the first curve is used. Optional when curve data is already paired. | |
| Curve With Y-Values | curve_y | vector | — | Y-axis values of the source curve (e.g., raw pressure in Pa or amplitude); cross-plotted against curve_x before the dB RMS conversion. Optional when curve data is already paired. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_to_pressure_db_rms_output_1 | curves_to_pressure_db_rms_output_1 | vector | Resulting curve with Y-values converted to pressure level in dB RMS (reference 20 µPa), suitable for direct use in NVH or acoustic reporting. |
