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.
