Perforated Acoustic Panels

Perforated acoustic panels

Perforated acoustic panels are a type of material used to isolate the propagation of sound waves, commonly used as noise reduction equipment in modern industrial production. They can reflect, absorb, or scatter sound waves, thereby reducing their propagation and impact.

Perforated acoustic panels are widely used as environmentally friendly noise control barriers for transportation and municipal facilities such as highways, railways, and subways that pass through urban areas, as well as sound-absorbing panels for sound insulation and noise reduction in building walls, generator rooms, factory buildings, and other noise sources, and can be used for the ceilings and wall panels of buildings.

Materials: As far as perforated metal sound absorbing panels are concerned, galvanized aluminum plates, galvanized steel plates, aluminum alloy endurance plates, and foam aluminum are more widely used. Although materials such as sponge, glass wool, and rubber have better sound insulation effects, metal perforated acoustic panels are still favored by multiple industries due to their better durability, fire resistance, and corrosion resistance.

Surface treatment: High-pressure electrostatic spraying (various colors can be sprayed according to requirements), fluorocarbon spraying, oxidation, galvanization, etc.

Customized services: Our company can produce perforated metal sound absorbing panels according to the materials, plate thickness, aperture, hole spacing, arrangement, punching area size, and surrounding edge size provided by users. We can also provide services such as leveling, rolling, cutting, bending, edging, and argon welding molding for perforated acoustic panels.

How to Choose Suitable Perforated Metal Acoustic Panels

Material : The materials used for perforated acoustic panels are diverse, and most materials have some sound insulation effects. Generally speaking, materials with high sound insulation performance have been specially processed. Therefore, when choosing perforated acoustic panels, it is essential to consider the sound insulation degree of the material.

Installation method: High-quality perforated acoustic panels are usually easy to install, which can maximize their sound insulation effect.

Thickness and weight: Good perforated acoustic panels do not need to optimize sound insulation performance through thickness. Our perforated acoustic panels are lightweight and aesthetically pleasing, with lower requirements for load-bearing capacity.

Product performance: Our perforated acoustic panels have an average sound insulation value greater than 37dB and an average sound absorption coefficient greater than 0.84.

The main purpose of perforated metal sound-absorbing panels is to prevent sound reflection by allowing the incident sound waves to vibrate in a cavity with a small inlet and a large outlet. Perforated metal sound-absorbing panels can be divided into three types: porous, resonant, and composite. According to their appearance and structure, they can be classified as porous, perforated, thin wax, thin plate, and strong sound-absorbing construction. The principle of perforated metal sound-absorbing panels is the Helmholtz resonance sound absorption principle, which utilizes the special structure of punched plates. Sound waves collide with the plate wall and the bottom surface of the cavity, as well as with each other, to dissipate sound energy, thereby achieving the purpose of sound absorption.
