Audimute isole Sound Barrier and Absorption Sheet is designed as a combined sound absorption and sound blocking solution that integrates eco-C-tex absorption material with a layer of 1/16 inch Mass Loaded Vinyl (MLV). Marketed as a 2-in-1 system, this sheet targets both airborne sound reflection within a space and sound transmission through structural weak points such as doors and windows.

Design and Material Construction
This solution incorporates proprietary eco-C-tex sound absorption material made from recycled cotton and cellulose fibers. The manufacturer specifies a Noise Reduction Coefficient (NRC) rating of 0.75, indicating that it absorbs an average of 75 percent of sound waves that contact the surface. Behind the absorption layer is a 1/16 inch MLV barrier rated at STC 20, adding dense mass intended to help block sound waves from transmitting through the sheet.
For those evaluating a sound barrier and absorption sheet with MLV, this construction combines porous absorption and mass loading within a single hanging panel.
Dimensions, Weight, and Installation
The sheet measures 82 inches by 34.5 inches and weighs approximately 18 pounds. It is designed to fit over standard residential interior doors and includes three metal grommets along the top edge. Hanging hardware is included, allowing installation above doors, windows, or other application points.
Because of its weight, secure mounting is required. The design is portable rather than permanently fixed, allowing repositioning as needed. Those seeking a portable soundproofing sheet for doors or windows will find that the dimensions align with common doorway measurements.
Performance Characteristics
The 0.75 NRC rating reflects sound absorption performance for reducing echo and reverberation, while the STC 20 rating corresponds to the Mass Loaded Vinyl layer’s contribution to sound blocking. The manufacturer notes that effectiveness depends on application, and that sound can travel through gaps where air passes.
For door applications, the sheet should cover the entire door surface for optimal results. Performance varies depending on sound frequency and amplitude. Users considering a door sound blocking and absorption solution may view this configuration as reinforcement for existing structures rather than a structural replacement.
Material Safety and Cleaning
The absorption core is described as non-toxic and non-carcinogenic, and it contains no fiberglass. The eco-C-tex material is composed of recycled cotton and cellulose fibers. Cleaning instructions specify that the sheet is not machine washable and should be cleaned with water-based cleaning agents, foam, or water-free solvents, along with vacuuming or light brushing to prevent dust accumulation.
Commonly Reported Characteristics
Customer feedback frequently mentions the sheet’s weight and density. Installation experiences vary depending on mounting surface and hardware use. Reviews commonly describe noticeable reduction in noise transmission when the sheet fully covers the application area and when gaps are addressed. Mixed feedback appears regarding overall isolation results, often tied to installation conditions and surrounding air gaps.
Pros
- Combines 0.75 NRC absorption with STC 20 MLV barrier
- Constructed from recycled cotton and cellulose fibers
- Non-toxic and free of fiberglass
- Portable design with included hanging hardware
- Designed to fit standard interior doors
Cons
- Approximately 18 pounds, requiring secure mounting
- Effectiveness depends on full coverage and gap sealing
- Not machine washable
- Performance varies based on sound frequency and installation method
Application Considerations
This type of MLV sound blocking sheet is intended for reinforcing doors, windows, and other structural weak points. It may also be positioned within a room to reduce echo at reflection points. By combining absorption and mass loading in a suspended panel format, the system provides a defined approach centered on NRC 0.75 absorption and STC 20 sound blocking performance.
