The Modern Solution for Tuned Mass Damping


Hummingbird Kinetics provides a compact, flexible, and easy-to-service alternative to slosh tanks and pendulums.

The Hummingbird was developed by Thornton Tomasetti based upon their renowned expertise in large building design and engineering.

The Hummingbird is a competitively priced fluid harmonic damper that can be distributed throughout a building, improving efficiency and giving more leasable space back to the building owner.  

“The Hummingbird was half the price of other systems and worked exactly as promised. It was a great solution for us.”

Bob Sanna, Forest City (NYC)

“Compared to heavy steel plates and complex equipment, the Hummingbird was inexpensive and a piece of cake to install.”

Don Banker, Banker Steel (NYC)


Unlike competing solutions, the Hummingbird preserves design freedom and valuable floorspace while minimizing the risk of malfunctions or leaks.
