Sound level dependence and the respective factors of subjective volume (loudness), objective sound pressure (voltage), and acoustic power (sound intensity).
It is not easy to understand the relationship between these terms:
There is the subjective and artificial perceived concept of loudness, the measurable voltage at a microphone which is proportional to the sound pressure and there is the calculated sound intensity or acoustic power.
How many decibels (dB) is twice (double, half) or three times as loud?
Loudness/Volume - What is the dependence of the level in decibels? Scroll down to related links and look at "Sound level dependence and the respective factors" and when you think of "sound pressure" look at "Sound pressure p and the inverse distance law 1/r".
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.
The gravitational force is inversely proportional to the square of the distance. For example, if you increase the distance by a factor of 10, the force will decrease by a factor of 100 (10 squared).The gravitational force is inversely proportional to the square of the distance.

Decibel is a logarithmic formula; every 10 decibels is an increase by a factor of 10. Therefore, you calculate the ratio as 1046/10.
The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.

Decibel is no real unit, it is a pseudo unit. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity. A change in voltage ratio by a factor of two is approximately a 6 dB change. A change in power ratio by a factor of two is approximately a 3dB change.
The current rate of expansion of the Universe is such that distance would double after 14.4 billion years, so in a billion years, distance would increase by a factor of 1/14.4. About 7%.
Decrease
The factors of 2 are 1 and 2. If you increase something by a factor of 2, you double it. If you decrease something by a factor of 2, you halve it.
Decibel is a logarithmic formula; every 10 decibels is an increase by a factor of 10. Therefore, you calculate the ratio as 1046/10.
If you increase a shape by a scale factor of 2, you double the height and double the width. If you increase a shape by a scale factor of 3, you treble the height and treble the width. If you are interested in doing this mechanically, use a pantograph.
The area will increase by a factor of 4 in this case.
