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".

If the intensity of a sound is increased by a factor of 100 what will the new decibel level be?

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.


When a sounds intensity increases by a factor of 10 its decibel reading increases by what?

When a sound's intensity increases by a factor of 10, its decibel reading increases by approximately 10 decibels. This is because the decibel scale is logarithmic, with each 10-fold increase in intensity equating to a 10 dB increase in perceived loudness.


When a sounds intensity increases by a factor of 10 its decible reading increase by?

When a sound's intensity increases by a factor of 10, its decibel reading increases by 10 dB, following a logarithmic scale. This means that for every 10-fold increase in intensity, the decibel level increases by 10 dB.

What is a relationship between intensity and decibel?

Intensity is a physical quantity that measures the amount of energy per unit area, while decibel is a logarithmic scale used to express the relative intensity of a sound compared to a reference level. The relationship between intensity and decibel is non-linear; an increase in intensity by a factor of 10 corresponds to an increase of 10 decibels.

How will an increase in amplitude and power affect dB?

The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.

Does distance important on gravitational strength field?

Yes. The gravitational force is inversely proportional to the square of the distance; meaning, for example, that if you increase the distance by a factor of 10, the force will be reduced by a factor 100.Yes.

How is the energy of a sound wave related to its measured value on a decibal scale?

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.

How does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?

The electric force between two charged particles is inversely proportional to the square of the distance between them. If the distance is decreased by a factor of 3, the electric force will increase by a factor of (1/3)^2 = 1/9. This means the force will increase by a factor of 9 when the distance decreases by a factor of 3.


What is the decibel a unit of?

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.


What is the percentage by which the universe may be expanding every billion years?

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%.
