No, here we do not need the noise-canceling system, because we actually want the sound (and we want it loud!). What we want is the noise-CAPTURING bubble for outdoor parties, which will let us enjoy loud music in our backyard without disturbing our neighbors.
This idea should be applicable to small backyard parties, but also in the cities for festivals such as Ultra Miami, which happens in the heart of Miami. The technology could potentially be adapted to isolate traffic sounds, streets, trains, engines, etc.
The first idea was a giant bubble made of acoustic panels or sound absorbing material, but it's not practical due to the wind, the heat, the size of the bubble, and still the low noise-capturing features.
The second idea was the network of noise-canceling devices, which would be expensive and would undoubtedly affect the volume of the music at the festival (unless put in a smart, still unknown layout.
Do you have any ideas on how to create one? Which materials to use?
