The nature of sound and vibration is that it is variable and comes in many different forms. Simple categories include; deterministic, periodic, stationary, random, non-stationary &  transient. One method to separate periodic signals from random signals is to use averaging which, on the whole, works extremely well. But there are special cases where averaging doesn't work so well and careful consideration needs to be given to the appropriate approach.
