Understanding Linear and Decibel Scales

The conversion between linear values and decibels (dB) is fundamental in audio engineering, signal processing, and acoustics. Decibels provide a logarithmic scale that better represents how humans perceive sound intensity and other power ratios. This logarithmic nature makes it easier to work with large ranges of values.

Converting Between Linear and Decibel

The basic formulas are:

\( dB = 20 \log_{10}(x) \text{ (for voltage ratios)} \)

\( dB = 10 \log_{10}(x) \text{ (for power ratios)} \)

Applications

  • Audio engineering
  • Signal processing
  • Acoustics
  • Electronics design
