Not really. The decibel is a measurement of the intensityof sound. A Bel is a factor of 10 of a power source. A decibel is a tenth of a Bel and is a ratio of one quantity to a reference quantity, on a log scale. Many entities including distances, weights, and other physical entities could be expressed in decibels. So, in the case of sound, we typically will express the RMS (root mean square) pressure value against a reference pressure of 20 µPa (micropascals). Thus a pressure wave exerting a specific pressure is converted into a decibel by taking 20 times the log10 of the ratio of the measured pressure to 20 µPa.
Decibels are simply a measure of loudness. The loudness of any sound - loud or not so loud - can be expressed in decibels.

That depends on the amplitude of the sound pressure.

How loud is one decibel
A unit used to measure the intensity of a sound or the power level of an electrical signal. Someones voice could raise by a decibel.
About 20 dB SPL (sound pressure level).
A human ear capable of detecting sound at a level of around 12 hz. A decibel is not the correct measurement unit for measuring the human range of sound.
Use the definition of decibel. The factor can be calculated as is 10(83-70/10). = 101.3.

A decibel meter is a device used to measure sound. Specifically, it measures sound pressure level, and is also known as a sound level meter.
About 20 dB SPL (sound pressure level).
Sound is measured in decibels by a sound pressure level meter (SPL-meter).
The decibel scale is a logarithmic scale. Scroll down to related links and look at "Decibel - Wikipedia" and "Sound level meter - Wikipedia".
A decibel is a measure for sound.
dB HL stands for decibel Hearing Level, and dB SPL stands for decibel Sound Pressure Level.
It is an SPL meter. SPL means sound pressure level.
A human ear capable of detecting sound at a level of around 12 hz. A decibel is not the correct measurement unit for measuring the human range of sound.
It depends on how close at the car you measure the sound with a sound pressure level meter.
