Sound wave Amplifiication applied to price trends ... one day in the future ...

Sound wave is in my opinion the best representation of trend strength and behavior.

Price trend will go through different phases of strong amplification strength and low amplification dampening effect.

Trend can remain in a steady state of high volatility or low volatility with transition phase. 

Maybe one day sometime in the future ... one great physicist will be able to develop a system to mimic and predict using this approach.
