Indoor PET Acoustic Wall Panels for Noise Reduction

The Indoor PET Acoustic Wall Panels for Noise Reduction are made of high-density polyester fiber as a single material, offering excellent acoustic absorption. The surface can be CNC-carved into geometric, wave, or grille patterns. Dual-layer carving reveals the base color, creating a two-tone visual effect. 3D printing technology allows custom finishes including marble, travertine, wood grain, and any other pattern. CE and environmental certifications are held.

In-Depth Case: Acoustic Retrofit of a Coffee Chain Flagship Store in Seoul, South Korea

Project Background

A coffee chain flagship store in Gangnam, Seoul (approx. 200 m²) received frequent customer feedback: background noise was too high for comfortable conversation; during peak hours, the space became so noisy that average customer dwell time was under 20 minutes. The brand sought to improve the acoustic environment while maintaining a high-end visual identity.

Solution

Selected Wonear’s Indoor PET Acoustic Wall Panels for Noise Reduction:

● Main dining area: 12mm thick panels with wave carving pattern, light beige finish, covering approximately 45 m².

● Booth seating area: Partial installation of dual-layer carved panels – surface grooves revealing a dark gray base layer, creating a two-tone grille effect.

● Brand feature wall: Custom 3D printed marble texture finish with carved brand logo.

Panels were produced at Wonear’s factory in China, delivered within 12 working days. As a manufacturer, we provided installation drawings and remote guidance.

Results

Perceived reverberation significantly reduced – conversation clarity improved.

Brand operations director comment: “As a supplier, Wonear’s product exceeded expectations in both design and acoustic performance. The 3D printed marble texture is highly realistic and perfectly aligns with our brand’s premium positioning.”

Post-retrofit, average customer dwell time increased to over 40 minutes, with monthly foot traffic growing by 15% month-over-month.

FAQ

Q1: How many decibels of noise will this type of board reduce in a room?

A1: It can reduce mid-to-high frequency echoes, making the environment feel "3-5 decibels quieter" (a noticeable difference), but the actual sound pressure level reduction is usually only 2-4 dB. It does not insulate against sound and cannot block voices or street noise from outside the walls.

Q2: What are the advantages of PET boards compared to ordinary soft foam sound-absorbing panels?

A2: PET boards do not absorb water, do not trap dust, have a high fire resistance rating (B1), and the surface can be wiped with a damp cloth; while soft foam is prone to moisture absorption and mold, and produces toxic fumes when burned. PET boards are more suitable for indoor spaces with slightly higher humidity, such as basements and living rooms.

Q3: Will installing it in a home theater or music room reduce the "humming" bass boom?

A3: The effect is limited. PET boards mainly absorb mid-to-high frequencies (voices, string instruments) and are basically ineffective against low-frequency booms below 100Hz. To improve bass performance, you need to use a low-frequency trap or thicker sound insulation felt.
