Blown-in insulation with embedded mass pellets for broadband
This technology creates a vibration and sound-absorbing layer by mixing small discrete masses into loose insulation or thermal material, then blowing the mixture into walls, floors, or other structural cavities. Because the masses are distributed at different depths and spacings throughout the material, each mass-and-insulation pairing acts as a tiny tuned vibration damper at a different resonant frequency, collectively suppressing a broad range of noise and vibration. The system works passively with no electronics or power required and can be installed during construction or retrofit using standard blown-in insulation equipment. The result is a structural layer that simultaneously serves as thermal insulation and broadband acoustic/vibration control.
What you could build
A blown-in insulation product with embedded mass pellets sold to building materials distributors or installed by insulation contractors in residential and commercial wall and floor assemblies; automotive and marine OEMs could also use it as a cavity-fill dampening treatment.
Who in Virginia should care
Virginia-based homebuilders, commercial construction firms, and building materials distributors serving the Mid-Atlantic market; also defense contractors managing cabin noise in naval or ground vehicles.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
