Overview
Audimute isole Sound Barrier and Absorption Sheet combines eco-C-tex absorption material with 1/16-inch Mass Loaded Vinyl. It targets sound reflection inside a space and sound transmission through doors, windows, and other structural weak points.
Realistic expectations: The sheet is designed to combine sound absorption with sound blocking in one suspended panel. However, effectiveness depends on the application, sound frequency, sound amplitude, full coverage, and surrounding air gaps. Sound can still travel through gaps where air passes.
The sound barrier and absorption sheet uses two different acoustic principles. The porous layer absorbs sound waves, while the dense MLV layer helps block transmission through the sheet.
Key takeaways
- The sheet combines an NRC 0.75 absorption layer with an STC 20 MLV barrier.
- It measures 82 inches by 34.5 inches and weighs approximately 18 pounds.
- Three metal grommets and hanging hardware support placement above doors or windows.
- The eco-C-tex core uses recycled cotton and cellulose fibers.
- Full coverage and attention to air gaps affect sound isolation results.
- The sheet is portable and can be repositioned between application points.
What the product is designed to do
The sheet targets two sound-control tasks within one hanging format. First, the eco-C-tex surface absorbs airborne sound that reaches the material. Next, the MLV layer adds dense mass intended to help block sound waves from passing through the sheet.
Its NRC rating relates to absorption. NRC means Noise Reduction Coefficient, and the listed 0.75 rating represents average absorption of 75 percent of contacting sound waves.
STC relates to sound transmission through a barrier. The 1/16-inch MLV layer carries an STC 20 rating. Together, these layers form a 2-in-1 sound absorption and blocking system for doors, windows, and structural weak points.
This approach reinforces an existing structure rather than replacing it. In addition, the sheet may reduce echo when placed at reflection points within a room.
Materials, dimensions, and technical details
| Detail | Specification |
|---|---|
| Absorption material | eco-C-tex recycled cotton and cellulose fibers |
| Absorption rating | NRC 0.75 |
| Barrier material | 1/16-inch Mass Loaded Vinyl |
| Barrier rating | STC 20 |
| Dimensions | 82 inches by 34.5 inches |
| Weight | Approximately 18 pounds |
| Mounting points | Three metal grommets along the top edge |
| Included item | Hanging hardware |
The absorption core is non-toxic, non-carcinogenic, and free of fiberglass. Also, its recycled fiber construction differs from the dense MLV layer behind it.

Installation and placement notes
The sheet is designed to fit over standard residential interior doors. It can also hang above windows or other application points using the three top grommets.
Because the panel weighs approximately 18 pounds, it requires secure mounting. Also, installation experiences can vary with the mounting surface and hardware use.
For a door application, the material should cover the entire door surface for optimal results. Gaps matter because sound can travel wherever air passes. As a result, incomplete coverage may reduce isolation performance.
The portable format supports repositioning rather than permanent attachment. A separate 3 mm sound barrier overview covers another suspended barrier format.
Performance characteristics described
The NRC 0.75 rating relates to echo and reverberation control. It reflects the absorption layer’s ability to reduce sound energy that contacts its surface.
The STC 20 rating applies to the MLV layer’s contribution to sound blocking. However, overall performance varies with frequency, amplitude, placement, coverage, and surrounding air gaps.
The MLV sound blocking sheet combines porous absorption with mass loading. It does not function as a complete structural replacement. Instead, it reinforces doors, windows, and other weak points.
Its performance centers on two ratings: NRC 0.75 for absorption and STC 20 for the barrier layer. For additional MLV specifications, this mass loaded vinyl barrier overview covers a 1-pound-per-square-foot sheet format.
Review patterns buyers commonly mention
Buyer feedback often focuses on the sheet’s weight and density. Also, installation experiences vary with the mounting surface and hardware use.
Noise transmission reduction commonly connects with full coverage of the application area. However, mixed isolation results often connect with installation conditions and surrounding air gaps.

FAQ
What does the NRC 0.75 rating mean?
NRC measures sound absorption. A 0.75 rating represents average absorption of 75 percent of sound waves contacting the surface.
What does the STC 20 rating apply to?
The STC 20 rating applies to the 1/16-inch Mass Loaded Vinyl layer and its contribution to sound blocking.
Can the sheet cover a standard interior door?
Yes. Its 82-inch by 34.5-inch dimensions are designed to fit standard residential interior doors.
Does the sheet require permanent installation?
No. The design is portable and supports repositioning, though its weight requires secure mounting.
How should the sheet be cleaned?
Use water-based cleaning agents, foam, water-free solvents, vacuuming, or light brushing. The sheet is not machine washable.
Why do gaps affect performance?
Sound can travel through gaps where air passes. Full coverage helps the door sound blocking and absorption solution address the intended application area.
