Having thus described our invention, what we claim as new and desire to secure by Letters Patent is as follows: 1. Material for use in vibration or acoustic application, comprising: loose acoustic or thermal insulation material; and a plurality of discrete masses distributed within said loose acous
Having thus described our invention, what we claim as new and desire to secure by Letters Patent is as follows: 1. Material for use in vibration or acoustic application, comprising: loose acoustic or thermal insulation material; and a plurality of discrete masses distributed within said loose acoustic or thermal insulation material, or which are combined and distributed within said loose acoustic or thermal insulation material during a blowing operation, said discrete masses being distinct elements from the loose acoustic or thermal insulation material and being spaced apart from each other, said discrete masses including surfaces which are sticky to facilitate distribution of the discrete masses throughout the loose acoustic or thermal insulation material and to prevent the discrete masses from falling to a bottom portion of said loose acoustic or thermal insulation material. 2. The material of claim 1 wherein said loose acoustic or thermal insulation material is selected from the group consisting of foam, acoustic fiberglass, fiberglass batting, distributed spring material, urethane, and rubber. 3. The material of claim 1 wherein said plurality of discrete masses include masses of different sizes and shapes. 4. The material of claim 1 wherein said plurality of discrete masses are selected from the group consisting of metals, ceramics, gels and plastics. 5. The material of claim 1 wherein said plurality of discrete masses are metal masses. 6. Material for use in vibration or acoustic application, comprising: loose acoustic or thermal insulation material; and a plurality of discrete masses distributed within said loose acoustic or thermal insulation material, or which are combined and distributed within said loose acoustic or thermal insulation material during a blowing operation, said discrete masses being a distinct element from the loose acoustic or thermal insulation material and being spaced apart from each other, said discrete masses being selected from the group consisting of metals, ceramics, and gels and said discrete masses each being of a homogenous composition, and having surfaces which are sticky. 7. The material of claim 6 wherein said plurality of discrete masses include masses of different sizes and shapes. 8. The material of claim 6 wherein said loose acoustic or thermal insulation material is selected from the group consisting of foam, acoustic fiberglass, fiberglass batting, distributed spring material, urethane, and rubber. 9. The material of claim 6 wherein said discrete masses are metal masses. 10. Material for use in vibration or acoustic application, comprising: loose acoustic or thermal insulation material; and a plurality of discrete metal masses distributed within said loose acoustic or thermal insulation material, or which are combined and distributed within said loose acoustic or thermal insulation material during a blowing operation, wherein said masses of said plurality of discrete masses have a weight ranging from 6-8 grams per mass, and wherein said material having said loose acoustic or thermal insulation material with said plurality of discrete masses distributed therein has a weight of 300-400 grams/16 ft2, and wherein said discrete masses each being of a homogenous composition, and having surfaces which are sticky. 11. The material of claim 10 wherein said plurality of discrete masses include masses of different sizes and shapes. 12. The material of claim 10 wherein said loose acoustic or thermal insulation material is selected from the group consisting of foam, acoustic fiberglass, fiberglass batting, distributed spring material, urethane, and rubber.
