-- A difference of 20 dB means the louder one is delivering 100 times as much
power as the softer one is.
-- The power delivered by any sinusoidal phenomenon is usually proportional to
the square of the amplitude. So the amplitudes would have to be in the ratio of
10 to 1. The louder one has 10 times the amplitude of the softer one.
The power or intensity of the louder one is 10 billion times the power or intensity of the softer one. Since the power or intensity is typically proportional to the square of the wave amplitude, the amplitude of the louder one is a mere 100,000 times the amplitude of the softer one.

If the intensity of a sound is increased by a factor of 100, the new decibel level will be 20 dB higher. This is because the decibel scale is logarithmic, so a 10-fold increase in intensity results in a 10 dB increase, and a 100-fold increase in intensity results in a 20 dB increase.
The decibel scale is a logarithmic scale. An increase of 10 points on the decibel scale means that the energy increases by a factor 10; an increase of 20 decibels means an energy increase by a factor of 10 x 10 = 100, etc.
More Decibels mean more power in the sound. large amplitudes also mean more power in the sound. In order to double the audible signal one uses quadruple energy. or.. to double the decibel output one must quadruple the energy input. Regards.

100 times. Each bel (10 decibels) is ten times as loud thus 20 to 40 is 100 times.
The intensity of a 40 decibel sound is 10 times greater than that of a 20 decibel sound. This is because the decibel scale is logarithmic, with each 10 decibel increase representing a 10-fold increase in intensity. Therefore, a sound that is 40 decibels is 10 times more intense than a sound that is 20 decibels.
100 times louder. You will hardly hear a 20 db(SPL) sound at all.
If the intensity of a sound is increased by a factor of 100, the new decibel level will be 20 dB higher. This is because the decibel scale is logarithmic, so a 10-fold increase in intensity results in a 10 dB increase, and a 100-fold increase in intensity results in a 20 dB increase.

The unit is the decibel, based on a larger unit called a bel. The decibel is measured as a magnitude on a logarithmic scale, and has no dimension as such. An increase in the numerical value therefore indicates an exponential (logarithmic) increase in the actual intensity or power. Example : an increase of 3 dB is approximately twice the power, an increase of 10 dB is 10 times the power, and an increase of 20 dB is 100 times the power.
A lovebird has no decibel. The closer your ear is to a sound source the louder it will be. We measure the sound pressure level (SPL) in decibels at a distance. Laymen are happy knowing a fantasy "decibel of 100 dB". But without any distance such value is really nonsense.

Given: Sound intensity level LI1 = 40 dB and sound intensity level LI2 = 20 dB. Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing) Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level) Get sound intensity I1 when entering sound intensity level LI1 = 40 dB: Sound intensity I1 = Io×10^(LI/10) W/m² = 10^−12×10^(40/10) = 0.00000001 W/m² = 10^−8 W/m². Get sound intensity I2 when entering sound intensity level LI2 = 20 dB: Sound intensity I2 = Io×10^(LI/10) W/m² = 10^−12×10^(20/10) = 0.0000000001 W/m² = 10^−10 W/m². The sound intensity I1 = 10^−8 W/m² is 100 times more than the sound intensity I2 = 10^−10 W/m². The sound intensity level LI1 = 40 dB is 20 dB more than the sound intensity level LI2 = 20 dB.
