## Decibel Scale The decibel scale expresses sound intensity on a logarithmic scale relative to a reference intensity. ### Formula **dB = 10 * log10(I / I_0)** where I_0 = 10^-12 W/m². Every 10 dB increase represents a tenfold increase in intensity. A 3 dB increase doubles the intensity.

हल किया गया उदाहरण

A sound with intensity 0.001 W/m².

  1. 01dB = 10 * log10(I / I_0)
  2. 02dB = 10 * log10(0.001 / 1e-12)
  3. 03dB = 10 * log10(1e9)
  4. 04dB = 10 * 9 = 90 dB
