The decibel level slowly increases and how much power it is producing quickly increases but not as quickly as stated in the webpages!
there is no fixed number of times between two decibel levels and different measuring object will be having different number of objects at the same decibel for the next decibel level and a decibel level can be any number of decibels!
by it's pitch
-------------------------------------------------------------------------
Not by its pitch, but by a microphone calibrated in decibels.
0 decibels (dBs) is a sound at the threshold of hearing, 10 dBs is ten times stronger, 20 decibels is 100 times stronger than the threshold, 30 decibels is 1000 times stronger, etc.
It depends on how far you are from the object that is making the sound. So the closer you are to the object that's making the sound, the louder it is to you.
Because your eardrums are moved by the sound pressure of the air, you really don't mean the "intensity". We measure the sound pressure by a sound pressure level meter.
Scroll down to related links and look at "Sound level meter - Wikipedia".
The scale of an analog SPL meter is much better to read than a digital SPL meter.
Well, if you want, you could use echo location. Echo Location is what dolphins and bats use to hear and locate. Also, a more familiar example of "Echo" is when you yell intop the mouth of a cave, and your voice is repeated back to you several times.
Your ears and the sound pressure level meter "measure" the sound pressure of a sound wave. Sound intensity is measured in watts per square meter.
Note: Sound power (sound intensity) is the cause -
and the sound pressure is the effect.
The effect is of particular interest to the sound engineer.
Sound intensity or acoustic intensity (I) is defined as the sound power Pac per unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity. So we measure the sound with a SPL meter (Sound Pressure Level).
Sound intensity or acoustic intensity (I) is defined as the sound power (Pac) per unit area (A). The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity (measured in W/m²).
Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity (measured in pascals Pa). So we measure the sound with a SPL meter (Sound Pressure Level) in decibels.
There are meters to measure the sound pressure or the sound pressure level of the sound.
That is a measuring microphone, an amplifier, a voltage meter, and a noise weighting filter.
it is mesured in decebels (db) and is mesured with a decemeter. for reference a racing dirt bike is about 90-100 db
Sound is measured in Decibels (dB)
Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).
You take a measuring microphone with a sound pressure level meter.
The unit of sound intensity I is watts per meter squared (W/m²). Sound intensity is a sound energy quantity. Sound pressure deviations are moving our eardrums. The unit of sound pressure p is pascals (Pa) or newton per meter squared (N/m²). Sound pressure is a sound field quantity. Another answer: The most common unit of sound intensity is the decibel (dB). Reply: No! We got the sound intensity measured in W/m² and the sound intensity level we measure in decibels (dB). The question was "sound intensity".
Loudness is determined by the amplitude of the sound waves.
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.
Sound intensity I is measured in watts per meter squared (W/m²). Look at the link: "Conversion of sound units (levels)".
The sound intensity is defined as the sound power per unit area and is measured in watts per square meter. But our ears are sensitive only to the sound pressure, measured in pascals or newtons per square meters. Scroll down to related links and look at "Table of sound levels".

Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).

There we got: Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power). Scroll down to related links and study: "Dependance of sound levels and the corresponding factors".

Sound intensity is measured in watts per meter squared (W/m²) Sound intensity level is measured in decibels (dB). Sound intensity is a sound energy quantity. Our eardrums are moved by sound pressure variations. That is a sound field quantity. Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of human hearing). Reference sound pressure level Lpo = 0 dB-SPL (Threshold of human hearing sound pressure level). Sound pressure is measured in pascals (Pa) or in newtons per meter squared (N/m²).

Sound intensity is measured in a increment called a decibel, and its characteristics are decribed in terms of its frequency , wavelength, and amplitude.
