Polyester Fiber Acoustic Panels
These panels are made from compressed polyester fibers and offer good sound absorption. They are commonly used in commercial and educational settings.
Acoustic Sealant
A flexible, paintable sealant used to fill gaps and cracks to prevent sound leakage. Commonly used around door frames, windows, and in construction joints.
Rubber Floor Underlayment
Rubber material placed under flooring to reduce impact noise and vibration. It's effective in multi-story buildings where footfall can be an issue.
Bass Traps
Acoustic energy absorbers designed to dampen low-frequency sound waves. They are typically placed in the corners of rooms to control bass frequencies.
Soundproof Drywall
A type of drywall that has been engineered to reduce noise transmission. It usually combines multiple layers of gypsum and other materials for increased mass and density.
Acoustic Foam
Lightweight, open-celled foam used for sound absorption. Reduces echo and reverb in studios and theaters.
Mineral Wool
Mineral fibers spun from molten rock or steel slag. It provides good thermal insulation and fire resistance in addition to sound absorption.
Acoustic Ceiling Tiles
Tiles designed to reduce noise transmission through the ceiling. They provide a combination of sound absorption and sound blocking.
Green Glue
A viscoelastic damping compound used between layers of drywall to dampen vibrations and decrease sound transmission.
Acoustic Curtains
Heavy drapes made from dense materials that can absorb sound waves and reduce noise. Often used in home theaters and recording studios.
Acoustic Panels
Panels that dampen noise by reducing the reflection of sound waves. Typically made of foam or mineral fibers and used in rooms that require noise control.
Mass Loaded Vinyl (MLV)
A limp, heavy material used to block sound. Made of vinyl loaded with barium sulfate or calcium carbonate for added mass.
Acoustic Partitions
Portable walls used to divide spaces and reduce noise. They can be made of foam, fabric, or other sound-absorbing material.
Perforated Metal Acoustic Panels
Metal panels with a perforated surface and an acoustically absorbent backing. They provide sound absorption and can also be used for architectural design purposes.
Fabric Wrapped Acoustic Panels
These are acoustic panels wrapped in fabric to provide sound absorption while offering an aesthetically pleasing look. Commonly found in theaters, offices, and auditoriums.
