Observational facts: New York City - a real test and listening environment for seismic activity.
“Earth crust motion, other earth vibration, wind, footfall, traffic, subway, ocean wave action, local construction, large fans and speaker feedback”
Speaker feedback? (Only if you are a poor sound engineer :)
Add to that El trains (but not so much in Manhattan), subterranean city and workers 24-7, rivers, shipping and large engines, cab drivers complaining, aircraft, crowds of humanity singing and dancing, plates, glasses and bottles clattering, live band instruments (acoustic and electronic) and percussion and any other type of noise you can imagine…
And the liquid in the glass remains stable, not only stable but there are no discernable opposite reactions of the waves hitting the glass; would not they come back then forth again creating even greater instability of the fluid surface? Still extremely calm with a powerhouse subwoofer system beneath and a 1500 watt satellite system direct coupled to the subwoofer cabinet then add to that another pair of identical cabinets located on stage left and a half dozen floor monitors too!
Now that is what I call a full frequency range testing environment.
Clearly more energy heading to ground (flooring) versus coming up the chain.
