.. _auto_curve_to_pressure_db_rms:

*CONVERT CURVE TO PRESSURE DB RMS*
==================================

Converts a time- or frequency-domain curve into pressure levels expressed as decibels RMS (dB re 20 µPa). Use this worker when you need to transform raw pressure or signal amplitude data into acoustically meaningful dB RMS values for NVH or acoustics post-processing.

When to use

     - Input curve (vector of amplitude vs. time or frequency) to be converted to pressure dB RMS; supply a pressure-unit signal for physically meaningful results — optional if the curve is piped from an upstream worker.
