Yes, I'm in the USA. The existing building is a two-story home with shallow foundation and light-frame construction, combination of stone and stucco.

I came across a new type of soundproofing involving broadband and subwavelength absorbers. They contain structures that reduce the thickness and weight of acoustic treatments, making them significantly better at absorbing acoustic energy at very low frequencies. Allegedly, walls can be made to subdue various types of noises, even those from the intense vibrations of MRI machines.

One researcher said the possibilities are endless since this type of noise mitigation method can be customized to suit nearly any environment: "The idea is that we can now mathematically design an object that can block the sounds of anything."

I wonder where the public might be able to customize and purchase such acoustic-silencing metamaterials because compared to the unsightliness and heaviness of today's sound barriers, these are lightweight, open, and beautiful and can be used as tiles or bricks to scale up and build sound-canceling, permeable walls.
