Amplitude of sound is?
Answer:
measured in decibels.the measure of the amount of energy in a sound wave
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.
measured in bels or more commonly in decibels
See: http://www.indiana.edu/~emusic/acoustics...
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!
