Abstract

An acoustical partition for use in home, office and industrial environments includes a generally rectangular, rigid, hollow frame whose interior opening is filled with an acoustical core wherein the outer planar surfaces of the frame and core are covered with further insulation material and a fabric outer layer. The interior acoustical core is configured with an alternating sequence of insulation material strips wherein the alternating strips of insulation material may either be different materials of the same density, the same material with different densities, different materials and different densities and with all of the foregoing may be either the same or different thicknesses.

Claims

1. An acoustical partition comprising:

a frame including a top portion, a bottom portion, a first side portion and an oppositely disposed second side portion which collectively define an interior opening;

an acoustical core disposed within said interior opening, secured to said frame; and

said acoustical core including a side-by-side, lateral series of insulation strips sized so as to occupy the interior opening of said frame said series of insulation strips including a first plurality of insulation strips having a first material density and a second plurality of insulation strips having a second material density which is different from said first material density.

2. An acoustical partition comprising:

a frame including a top portion, a bottom portion, a first side portion and an oppositely disposed second side portion which collectively define an interior opening;

an acoustical core disposed within said interior opening, secured to said frame; and

said acoustical core including a side-by-side, lateral series of insulation strips sized so as to occupy the interior opening of said frame wherein said series of insulation strips includes a first plurality of insulation strips of a first material and a second plurality of insulation strips of a second material which is different from said first material.

3. An acoustical partition comprising:

a frame including a top portion, a bottom portion, a first side portion and an oppositely disposed second side portion which collectively define an interior opening;

an acoustical core disposed within said interior opening, secured to said frame; and

said acoustical core including a side-by-side, lateral series of insulation strips sized so as to occupy the interior opening of said frame wherein said series of insulation strips includes a first plurality of insulation strips of a first material with a first density and a second plurality of insulation strips of a second material with a second density, wherein said first and second material with a second density, other and said first and second densities are different from each other.

4. An acoustical partition comprising:

a frame including a top portion, a bottom portion, a first side portion and an oppositely disposed second side portion which collectively define an interior opening;

an acoustical core disposed within said interior opening, secured to said frame;

said acoustical core including a side-by-side, lateral series of insulation strips sized so as to occupy the interior opening of said frame; and

means for covering said acoustical core, said covering means being applied over both front and back sides of said acoustical core, wherein said covering means includes, on each side of said acoustical core, a first layer of insulation material covered by an outer, second layer of fabric.

5. An acoustical partition comprising:

a frame including a top portion, a bottom portion, a first side portion and an oppositely disposed second side portion which collectively define an interior opening;

an acoustical core disposed within said interior opening, secured to said frame; and

said acoustical core including a side-by-side, lateral series of insulation strips sized so as to occupy the interior opening of said frame, the lateral stacking of said insulation strips extending from said first side portion to said second side portion, said series of insulation strips including a first plurality of insulation strips of a first material and a second plurality of insulation strips of a second material which is different from said first material, said insulation strips of said first plurality being disposed in alternating sequence with insulation strips of said second plurality.

6. An acoustical partition comprising:

a frame including a top portion, a bottom portion, a first side portion and an oppositely disposed second side portion which collectively define an interior opening;

an acoustical core disposed within said interior opening, secured to said frame; and

said acoustical core including a side-by-side, lateral series of insulation strips sized so as to occupy the interior opening of said frame, the lateral stacking of said insulation strips extending from said first side portion to said second side portion, said series of insulating strips including a first plurality of insulation strips of a first material with a first density and a second plurality of insulation strips of a second material with a second density, wherein said first and second materials are different from each other and said first and second densities are different from each other, said insulation strips of said first plurality being disposed in alternating sequence with the insulation strips of said second plurality.

7. The acoustical partition of claim 6 wherein the insulation strips of said second plurality have a greater material density than the insulation strips of said first plurality.
