## Abstract

A portable and storable device for acoustic modification with segments foldable back upon each other.

## Claims

### Claim 1

A device capable of acoustic reflection, or alternatively or concurrently, of acoustic absorption, comprising:
two or more panels, each comprising;
a front face,
a back face,
a top end,
a bottom end,
a first side,
a second side;
said two or more panels so adjacently disposed as to proximally align one or more said panel first sides with adjacent one or more panel second sides;
one or more said adjacently disposed first and second sides spanned from one to another respectively by one or more belts;
each said belt so disposed as to overlay two or more panel front faces or alternatively or concurrently, two or more panel back faces, or alternatively or concurrently each belt so disposed as to overlay one panel front face and alternatively or concurrently one panel back face.

### Claim 2 (depends on 1)

A device as in claim 1 having a coverture, said coverture covering the front face of one or more panels, said panels, if plural, adjacently disposed, so as to align one or more first sides proximal one or more second sides, leaving a gap between said first and second sides; said gap spanned by said coverture.

### Claim 3 (depends on 1)

A device as in claim 1, one or more top ends comprising a groove.

### Claim 4 (depends on 3)

A device as in claim 3 comprising one or more acoustic shield segments seatable in one or more said grooves.

### Claim 5 (depends on 3)

A device as in claim 3 comprising one or more visually transparent acoustic shield segments seatable in said one or more grooves.

### Claim 6 (depends on 3)

A device as in claim 3 comprising a key seatable in one or more said grooves.

### Claim 7 (depends on 1)

A device as in claim 1 having a top cover.

### Claim 8 (depends on 1)

A device as in claim 1 wherein said belt communicates with and can function as a hinge between adjacent panels.

### Claim 9 (depends on 1)

A device as in claim 1 wherein one or more belts comprise a plurality of layers.

### Claim 10

A portable and storable device capable of acoustic reflection, or alternatively or concurrently, of acoustic absorption, comprising:
two or more panels, each panel comprising;
a front face,
a back face,
a top end,
a bottom end,
a first side, and
a second side,
said one or more top ends comprising a groove, or alternatively or concurrently, said one or more bottom ends comprising a groove;
said two or more panels so adjacently disposed as to proximally align one or more said panel first sides with adjacent one or more panel second sides;
said adjacently disposed first and second sides spanned from one to another respectfully by one or more belts,
each said belt so disposed as to overlay two or more panel front faces or, alternatively or concurrently, two or more panel back faces, or alternatively or concurrently, each belt so disposed as to overlay one panel front face or, alternatively or concurrently, one panel back face;
a coverture, said coverture covering the front face of one or more panels, said panels, if plural, adjacently disposed, so as to align one or more first sides proximal one or more second sides, leaving a gap between said first and second sides; said gap spanned by said coverture;
one or more acoustic shield segments seatable in one or more said grooves,
one or more said acoustic shield segments being transparent; or alternatively or concurrently, being a key seatable in one or more said grooves.

### Claim 11 (depends on 10)

A device as in claim 10 having a top cover.
