Real Decibel Levels


I’m new to this forum and Audacity. How do I display the actual real dB levels on Audacity.


Audacity’s meters show dBFS

If you mean acoustic loudness that’s dB SPL (sound pressure level). There is no standard calibration between digital levels and acoustic levels. The acoustic loudness depends on your volume control, your amplifier and speakers, and how close you are to the speakers, etc.

However, there is a direct correlation. For example, if you reduce the digital level by 3dB the acoustic loudness also goes down by 3dB.
