Duct Pulse Toy Isolator question: How does a duct pulse toy isolator work?

[BuzzBuddies]

I've seen mentions of a duct vibration toy isolator, but I'm not sure what it does truly. Can somebody make clear how it works and what its benefits are?

[Silva]

A duct vibration toy isolator is designed to reduce vibrations and sound from ducted Hvac systems. It helps isolate the vibrations caused by the equipment to prevent them from transferring by the ducts and producing noise elsewhere.

It's crucial for maintaining comfort and reducing disturbance in environments where sound from Hvac systems can be a trouble. Those isolators usually use materials that absorb and dampen vibrations.

Are there specific situations where a duct pulse toy isolator is more beneficial? I'm curious about whether it's used in residential settings or more commonly in commercial or industrial applications.
