## Abstract

A portable acoustical blocking system is disclosed for use with a support comprising a sheet of acoustical blocking material bound by material edge. A reinforcing tape is affixed to the sheet of acoustical blocking material adjacent to the material edge. A plurality of hangers are secured to the sheet of acoustical blocking material and extending through the reinforcing tape and the sheet of acoustical blocking material for hanging the sheet of acoustical blocking material from the support for inhibiting the flow of acoustic energy between the first and second sides of the acoustical blocking material.

## Claims

### Claim 1

A portable acoustical blocking system for use with a support, comprising:
a sheet of acoustical blocking material having a first and a second side and bound by material edge;
said sheet of acoustical blocking material having a thickness of approximately one-eighth of an inch and a density of greater than one pound per square foot;
a flexible reinforcing tape permanently affixed to said first side of said sheet of acoustical blocking material adjacent to said material edge;
a plurality of hangers secured to said sheet of acoustical blocking material and extending through said reinforcing tape and said sheet of acoustical blocking material for hanging said sheet of acoustical blocking material from the support for inhibiting the flow of acoustic energy between said first and second sides of the acoustical blocking material; and
said sheet of acoustical blocking material and said reinforcing tape being flexible for enabling the entire portable acoustical blocking system including said sheet of acoustical blocking material and reinforcing tape to be rolled as a single unit for transportation.

### Claim 2 (depends on 1)

A portable acoustical blocking system as set forth in claim 1, wherein the support is a chain link fence.

### Claim 3 (depends on 1)

A portable acoustical blocking system as set forth in claim 1, wherein said material edge of said sheet of acoustical blocking material includes a first through fourth edge defining a perimeter of said sheet of acoustical blocking material.

### Claim 4 (depends on 1)

A portable acoustical blocking system as set forth in claim 1, wherein said sheet of acoustical blocking material comprises a sheet of flexible barium free formulation mineral filled to have a weight greater than one pound per square foot.

### Claim 5 (depends on 1)

A portable acoustical blocking system as set forth in claim 1, wherein
said sheet of acoustical blocking material comprising a barium free formulation mineral filled.

### Claim 6 (depends on 1)

A portable acoustical blocking system as set forth in claim 1, wherein said reinforcing tape comprises a woven polyester material.

### Claim 7 (depends on 1)

A portable acoustical blocking system as set forth in claim 1, wherein each of said plurality of hangers comprises a grommet defining a grommet aperture.

### Claim 8 (depends on 1)

A portable acoustical blocking system as set forth in claim 1, including a plurality of flexible ties for securing said plurality of hangers to the support.

### Claim 9

A portable acoustical blocking system for use with a support, comprising:
a sheet of acoustical blocking material having a first and a second side and bound by material edge;
said sheet of acoustical blocking material having a thickness of approximately one-eighth of an inch and a density of greater than one pound per square foot;
a reinforcing tape heat welded to said first side of said sheet of acoustical blocking material adjacent to said material edge;
said sheet of acoustical blocking material and said reinforcing tape being flexible for enabling the entire portable acoustical blocking system including said sheet of acoustical blocking material and reinforcing tape to be rolled for transportation; and
a plurality of hangers secured to said sheet of acoustical blocking material and extending through said reinforcing tape and said sheet of acoustical blocking material for hanging said sheet of acoustical blocking material from the support for inhibiting the flow of acoustic energy between said first and second sides of the acoustical blocking material.

### Claim 10 (depends on 9)

A portable acoustical blocking system as set forth in claim 9, wherein each of said plurality of hangers comprises a grommet defining a grommet aperture.

### Claim 11 (depends on 9)

A portable acoustical blocking system as set forth in claim 9, wherein each of said reinforcing tape and said first side of the sheet of acoustical blocking material are simultaneously heated to an appropriated temperature and said reinforcing tape is pressed upon said first side of said sheet of acoustical blocking material.
