Thickened Acoustic Panels 31.5 x 23.6 in Pack of 6 - Noise Dampening

Our review of these thickened acoustic panels finds them best for home studios, practice rooms and shared living spaces where reducing echo and reverberation matters most. The single biggest reason to buy is the panels' dense 100% polyester felt construction, which delivers a high NRC of 0.9 and a consistently warm, non-foamy look that doubles as decor and padding. Installation is straightforward and they are safe for family spaces thanks to flame retardant, non-toxic materials.

Key Features

• Size and coverage: Each panel measures 31.5 x 23.6 x 0.5 in and a pack of 6 covers about 31 sq ft, making it simple to plan treatment for medium rooms.
• Material and density: Made from 100% polyester fiber with a density of 9.4 lb/ft3, the felt surface contains many damping pores that help absorb unwanted reflections.
• Acoustic performance: The panels offer strong sound absorption with an NRC of 0.9 and an average absorption coefficient of 0.77, useful for cutting reverb and standing waves.
• Durability and appearance: Felt construction retains color over time and resists the discoloration that affects some foam treatments, so panels stay visually consistent.
• Safe and eco-conscious: The material is non-toxic, odorless, formaldehyde-free and Class B1 flame retardant, suitable for homes, schools and shared spaces.
• Easy to modify and install: Panels are simple to cut with a knife and can be mounted with adhesive, double-sided tape or small screws for minimal wall damage.

Who It's For

These panels are ideal for musicians, podcasters and home theater owners who need effective, unobtrusive acoustic treatment that also looks tidy. The pack size and sheet dimensions suit mid-sized rooms where a balance of coverage and aesthetics is desired.

They may be less appropriate for someone needing full professional studio isolation or very thin, peel-and-stick solutions; the panels are thicker and intended to be mounted with external adhesive or hardware for best results.

Pros & Cons

Pros

• High absorption performance thanks to dense polyester felt, which reduces echoes and reverberation effectively.
• Attractive felt finish that stays vivid over time and doubles as collision protection in busy spaces.
• Safe, non-toxic construction with Class B1 flame retardancy for family and school use.
• Simple to cut and install with common adhesives or screws, allowing flexible placement.

Cons

• Color expectations vary among users, so shades may not match every interior and some buyers report mixed impressions of whiteness.
• At 0.5 in thickness, they help absorb mid to high frequencies well but are not a substitute for deeper bass trapping solutions.

Frequently Asked Questions

Can I cut these panels to fit odd shapes?
Yes. The polyester felt is easy to trim with a utility knife for custom fits around fixtures or corners.

Will these stop noise from outside the room?
They primarily absorb internal reflections and reduce reverberation; they are not full soundproofing for external noise transmission.

How should I mount them to avoid wall damage?
Use construction adhesive, double-sided tape, or small screws; using external adhesive removes more cleanly than self-adhesive backing.
