Answer:

1 decibel represents an actual increase of .26  times in sound energy

Explanation:

Decibel

  • One decibel (0.1 bel) is equal to 10 times the power ratio's common logarithm.
  • The intensity of a sound is expressed mathematically as 10 log10 (S1/S2), where S1 and S2 are the intensities of the two sounds.
  • Doubling a sound's intensity corresponds to an increase of little more than 3 dB
  • A logarithmic approach to express a ratio between things like power, sound pressure, and voltage is the modest decibel.

Decibels rise in a linear fashion.

  • Logarithmic scales are used to measure decibels. This is a method of accounting for or measuring an exponentially growing quantity.
  • For instance, every 10 dB increase in decibels corresponds to a 10-fold increase in sound pressure level (SPL).
  • A sound measured at 10 dB is actually 10 times louder than one measured at near silence (0 dB). A sound of 20 dB is 100 times louder than almost complete silence.
