See: http://www.indiana.edu/~emusic/acoustics/amplitude.htm
Amplitude is the objective measurement of the degree of change (positive or negative) in atmospheric pressure (the compression and rarefaction of air molecules) caused by sound waves.
A decibel is a measurement used to compare the ratio of intensities of two acoustic sounds (or electronic signals).

It is said that air molecule amplitude/displacement is only 5 atom diameter!

It is how loud the sound it...
More technical??? Well if you convert the wave into a sine wave (transverse) it is the distance from the middle to the peak of a wave.
