.. _auto_curve_to_pressure_db:

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

Converts a time- or frequency-domain curve into pressure levels expressed in decibels (dB). Use this worker whenever raw pressure values need to be transformed to a logarithmic dB scale for NVH, acoustics, or signal-analysis workflows.

When to use

     - Input curve (e.g., time-history or frequency spectrum of pressure values in Pa or compatible units) to be converted to dB; leave unconnected to skip processing.
