Metal Sound Barrier_noise Barrier_height Style Can Be Customized

Metal sound barriers are a common type of noise control facility. They mainly reduce noise transmission through the sound insulation and sound absorption performance of metal structures and are widely used in transportation, industry, construction and other fields. The following is a detailed introduction to its specific functions and application scenarios:

I. The Main Functions of Metal Sound Barriers

Sound insulation and noise reduction

By taking advantage of the high-density characteristics of metal plates (such as aluminum plates and galvanized steel plates) to block the propagation of sound waves, noise can be reduced through reflection or absorption of sound energy, especially for medium and high-frequency noise (such as traffic noise and mechanical noise), the effect is particularly remarkable.

Some designs will combine sound-absorbing materials (such as rock wool and aluminum foam) to form a composite structure, enhancing the absorption capacity for low-frequency noise.

2. Environmental protection

Reduce the impact of noise on sensitive areas such as surrounding residential areas, schools and hospitals, and improve the quality of the acoustic environment.

In some scenarios, it can also serve as windproof and dustproof (such as along highways and railways).

3. Durability and Safety

Metal materials (such as aluminum alloy and stainless steel) are corrosion-resistant and weather-resistant, making them suitable for long-term outdoor use.

It has high structural strength and can withstand strong winds or unexpected impacts.

4. Aesthetics and customization

The appearance can be beautified through processes such as perforation and spraying, and it can be in harmony with the surrounding environment (such as the landscape sound barrier of urban elevated Bridges).

Ii. Typical Application Scenarios

1. Transportation field

- Highways/expressways: Separate lanes from residential areas to reduce noise from vehicle movement and honking.

- Railways/high-speed railways: Reduce track friction and train operation noise, commonly seen in urban elevated sections or areas close to communities.

- Urban elevated Bridges: Used in combination with transparent sound insulation boards, it takes into account both lighting and noise reduction.

2. Industrial field

- Factory boundary: Block the noise from mechanical equipment (such as fans and generators) to prevent disturbance to the residents.

- Power station/substation: Reduce the humming sound of transformers and cooling towers.

3. Field of architecture

- Commercial/residential areas: Used for noise isolation of rooftop equipment (air conditioning units, exhaust fans).

- Construction site: Temporary sound barriers reduce the transmission of construction noise.

4. Other scenarios

- Around the airport: Assist in reducing the noise from aircraft take-offs and landings (in conjunction with other sound insulation measures).

- Sound insulation renovation of walls in entertainment venues such as bars and KTVS.

Iii. Common Types of Metal Sound Barriers

1. Pure metal sound insulation barrier: Mainly made of galvanized steel plates and aluminum plates, it relies on the density of the material for sound insulation.

2. Composite sound barrier: Metal panel + sound-absorbing core material (such as rock wool, glass wool), integrating sound insulation and sound absorption.

3. Perforated metal Noise barrier: The panel is perforated and filled with sound-absorbing materials, optimized for noise in specific frequency bands.

Metal sound barriers are efficient and economical solutions in noise control engineering, especially suitable for noise control in traffic and industry. In practical applications, appropriate materials and structures should be selected based on noise frequency and environmental requirements. When necessary, green belts, soundproof Windows, etc. should be combined to form a comprehensive noise reduction system.
