  • What Are Decibels, and How Are They Measured? - HowStuffWorks
    Decibels serve as the universal yardstick for measuring sound intensity, capturing the vast range of audible sounds that the human ear can detect From the whisper-quiet rustle of leaves to the roaring blast of a jet engine, this logarithmic scale provides a nuanced way to understand sound levels
  • Decibel (dB) | Definition, Formula, Facts | Britannica
