Question 42

What if you feel your acoustic panels are "too muffled" or "over-absorbing" after installation?

Accepted Answer

It's true that over-absorbing sound can make a room sound "dry." Acoustic design emphasizes a combination of sound absorption and diffusion. Solutions:

Don't cover all walls; leave 30%~50% of hard reflective surfaces (such as drywall, glass, or untreated solid walls) untouched.

Use an "intermittent" installation (such as a checkerboard layout) and install quadratic residual diffusers (QRDs) in specific locations to achieve both clear and immersive sound.

Question 43

Does a more uneven surface on a sound-absorbing panel necessarily mean better sound absorption?

Accepted Answer

Not necessarily. The key to sound absorption lies in the material's flow resistance, porosity, and the cavity behind it, not simply the surface design. Surface grooves or embossing (such as wide or thin stripes) primarily enhance diffuse reflection and slightly increase the effective sound-absorbing surface area, but the improvement in the sound absorption coefficient is usually within 5%-10%. Don't just look at the appearance; pay attention to the NRC value measured using the reverberation chamber method.

Question 44

Why are polyester fiber sound-absorbing panels strongly recommended for kindergartens and early childhood education institutions?

Accepted Answer

Because they simultaneously meet three essential needs of early childhood education settings:

Absolute Safety: 100% free of fiberglass and asbestos, preventing skin irritation or inhalation into children's respiratory tract.

Collision and Cushioning: Flexible and elastic texture, providing some protection against bumps and knocks (superior to hard wood veneer or plasterboard).

Acoustic Environment: Reduces classroom reverberation, ensuring clear speech for teachers and protecting children's still-developing auditory systems.

Question 45

Are these sound-absorbing panels easy to clean in restaurants and cafes? Won't they absorb a lot of cooking fumes?

Accepted Answer

It's recommended to choose flat panels with a melamine finish or a high-density polished surface to minimize exposed pores in catering spaces. Even if they get lightly stained with oil, they can be wiped clean with a neutral degreaser and a damp cloth. However, please note: it's not recommended to install them directly above the kitchen exhaust vent, as prolonged high temperatures will cause grease molecules to seep into the interior and become difficult to clean. It's advisable to install a grease trap before proceeding with the installation.

Question 46

Does using polyester fiber sound-absorbing panels in open-plan offices really improve employee productivity?

Accepted Answer

Yes. The biggest challenge in open-plan offices is speech intelligibility interference. Covering key areas of the ceiling and walls with polyester fiber sound-absorbing panels can effectively reduce ambient background noise by 5-10 dB and lower the speech interference level (LPR) by one level, reducing the number of times employees are distracted by noise. Real-world testing shows an improvement in cognitive focus of approximately 15%.

Question 47

How does your factory ensure product consistency (color difference and thickness tolerance) for long-term export orders?

Accepted Answer

Our factory implements a strict batch control process:

Color difference: Each color adjustment uses a spectrophotometer (ΔE < 1.0 color difference value control), and a standard color sample is retained for comparison.

Thickness: We use an online laser thickness gauge for real-time monitoring to ensure that thickness tolerance is strictly controlled within ±0.3mm, far exceeding the industry standard (JC/T 2704-2022 requires ±0.5mm).

Question 48

What is the correspondence between the Chinese national standard B1 fire resistance rating and international standards (such as ASTM E84 or BS 476)?

Accepted Answer

The Chinese national standard B1 (GB 8624) classifies materials as flame-retardant. In the North American ASTM E84 test, a flame spread index (FSI) ≤25 and a smoke index (SDI) ≤450 constitute Class A (the highest level), and high-quality flame-retardant polyester fiberboard can reach this level. The British BS 476 Part 7 corresponds to Class 1. If the customer has specific export requirements, please inform us of the target country when requesting a quote, and we can adjust the flame-retardant formula for testing according to specific standards.

Question 49

What key testing reports are required for products exported to Europe or North America?

Accepted Answer

The core certification requirements are as follows, depending on the market:

For export to the EU: EN 13501-1 (fire resistance rating, typically B-s2, d0) and REACH or RoHS (hazardous substance testing) reports are required.

For export to North America: ASTM C423 (acoustic absorption test) and ASTM E84 (surface flammability test, Class A preferred) are required.

Generally: ISO 9001 factory management system certification is a basic requirement. Our factory can provide testing reports in full English.

Question 50

Can sound-absorbing panels be perforated or carved to enhance their design?

Accepted Answer

Yes. Various geometric perforations and openwork techniques can be achieved using a CNC engraving machine. However, please note that large-area perforations will significantly reduce the actual sound-absorbing area. If perforations are used for decorative purposes, it is recommended to place a layer of black sound-permeable fabric and non-woven fabric behind the perforated back panel. This ensures visual appeal while preventing the back cavity from being exposed, and the sound-permeable fabric still retains some sound-absorbing functionality.

Question 51

How to achieve a flush joint between sound-absorbing panels and other materials (such as wood veneer or hard paneling) on the same wall?

Accepted Answer

The key lies in the precise control of the base layer thickness. Before installation, based on the total thickness of the polyester fiber sound-absorbing panels (e.g., 12mm) and other materials (e.g., 9mm wood veneer + 3mm underlayment), leveling layers of plywood or framing at different heights should be applied to the wall surface to ensure that the finished surfaces of all materials are on the same horizontal plane. Finally, a T-shaped trim strip should be embedded at the joint for a smooth transition.

Question 52

Will digital printing on sound-absorbing panels affect the sound absorption effect?

Accepted Answer

The impact is very small. High-quality UV inks or water-based penetrating inks, with a coating thickness of only 0.02-0.05mm, will only seal a very small number of micropores on the very surface, and the impact on the overall noise reduction coefficient (NRC) is negligible (usually a reduction of <0.05). However, it is crucial to avoid using paint for spraying, as paint will seal large areas of pores and severely impair the sound absorption function.

Question 53

Can polyester fiber acoustic panels be customized with wood grain, stone grain, or fabric textures?

Accepted Answer

Absolutely. Through heat transfer printing or digital UV flatbed printing, any wood grain, stone grain, geometric pattern, or artistic image can be precisely replicated onto the surface of the acoustic panel. The pattern layer is extremely thin, barely affecting the original sound-absorbing porosity. Our factory offers custom design services based on provided images. Please consult our sales manager for the minimum order quantity.

Question 54

How to prevent glue from overflowing from the seams and staining the board surface during installation?

Accepted Answer

The "wall-applying glue method" should be strictly used (glue is only applied to the wall substrate), not the back of the board. If glue accidentally spills, immediately wipe it gently with a damp cloth soaked in alcohol or a special cleaner. Do not wait for the glue to dry completely before scratching it off, otherwise it will damage the texture and color of the board surface.

Question 55

Can polyester fiber acoustic panels be used on curved walls or to wrap cylinders?

Accepted Answer

Absolutely. Polyester fiber acoustic panels are flexible; 9mm thick panels can be safely bent into curves with a radius greater than 300mm, and for 12mm thick panels, a minimum bending radius of 500mm is recommended. During installation, it is recommended to use dry-hanging or keel fixing methods to avoid using rigid adhesives that restrict the bending stress of the panels.

Question 56

How should holes be drilled for sound-absorbing panels if there are switches, sockets, or fire hydrants on the wall?

Accepted Answer

The safest method is to "install first, then drill the holes." First, use a utility knife or jigsaw to roughly drill holes in the panel that are about 5mm smaller than the actual equipment. After attaching the panel to the wall, use an edge trimmer or fine-toothed saw to precisely trim along the edges of the equipment. If you are drilling the same holes in batches, it is recommended that the factory provide a pre-drilling customization service so that the panels can be directly fitted on-site, greatly improving efficiency and reducing dust.

Question 57

How to aesthetically treat inside and outside corners when installing polyester fiber sound-absorbing panels?

Accepted Answer

Outside corners (convex corners): It is recommended to cut the panels into 45° diagonal joints (split corners), or use special aluminum alloy outside corner trims. This protects the corners from bumps and adds a clean, streamlined look.

Inside corners (concave corners): Two panels can be directly butt-jointed tightly, with the gap controlled within 1mm. Apply neutral, mildew-resistant silicone sealant to seal the joint, or use inside corner trims to finish the edge for a clean and neat appearance.

Question 58

Can polyester fiber acoustic panels solve the problem of low-frequency standing waves? How effective are they when used alone?

Accepted Answer

Single-layer polyester fiber acoustic panels excel at absorbing mid-to-high frequencies, but their absorption capacity for extremely low frequencies (<100Hz) is limited. To address low-frequency standing waves, a composite structure is recommended: add a cavity of at least 50mm between the acoustic panel and the frame, filled with high-density sound-absorbing cotton, or use it in conjunction with a thin-plate resonant sound-absorbing structure. For home theaters or recording studios, it is recommended to combine them with low-frequency traps for comprehensive treatment.

Question 59

What specific impact does the cavity depth on the sound absorption effect of the acoustic panel's back?

Accepted Answer

The cavity depth primarily affects the position of the low-frequency absorption peak. A deeper cavity results in better absorption of lower frequencies (for example, a 100mm cavity can significantly improve the low-frequency absorption coefficient around 125Hz). It is recommended to adjust the cavity depth between 50mm and 200mm, with a 50mm cavity being the generally recommended depth, effectively enhancing low-frequency performance without significantly sacrificing space.

Question 60

How to initially calculate how many sound-absorbing panels are needed for a room?

Accepted Answer

A simple estimation method is to first measure the total surface area of ​​the room (four walls + ceiling + floor, the floor is usually excluded), and then determine the coverage of the sound-absorbing material based on the target reverberation time. It is generally recommended to cover 30% to 60% of the total wall or ceiling area. Precise calculations require Sabine's Formula: T60 = 0.161V / A (where V is the room volume and A is the total sound absorption). It is recommended to provide the room dimensions and intended use to the manufacturer so that an acoustic engineer can provide a professional layout plan.

Question 61

What is the typical warranty period for polyester fiber sound-absorbing panels?

Accepted Answer

Under normal indoor conditions, the product can be used for 5-10 years or more. The specific warranty period varies depending on the manufacturer; it is recommended to confirm the warranty terms with the supplier at the time of purchase. The product material is stable and will not naturally decompose or release harmful substances over time.

Further additions or adjustments can be made based on actual customer feedback.

Question 62

Can polyester fiber acoustic panels be customized in size and color?

Accepted Answer

Yes. Standard panel sizes are generally 1220×2420mm or 1220×2440mm, with thicknesses typically 9mm and 12mm. Other sizes, thicknesses, colors, and surface textures can be customized to meet customer requirements. Over 40 colors are available.

Question 63

What surface treatments are available for polyester fiber acoustic panels?

Accepted Answer

Common surface treatments include flat surfaces, square (mosaic) patterns, wide strips, thin strips, embossed textures, and various other patterns. The panels can also be bent into curved shapes to meet different decorative style requirements. Some products support computer-printed artwork onto the acoustic panels for personalized decoration.

Question 64

What factors influence the price of polyester fiber acoustic panels?

Accepted Answer

Price is affected by factors such as thickness, density, fire resistance rating, surface treatment, color, and quantity purchased. Custom sizes, special colors, and artistic pattern printing will increase costs. Bulk purchases are recommended to reduce the unit price.
