The silencer column has the following characteristics:

1. It is usually a columnar structure.

2. Made of sound-absorbing material, it absorbs noise and reduces its propagation distance.

3. A plurality of silencer columns are arranged in the frame, and the silencer columns are arranged in the frame.

4. The muffler column includes a flow guide cover, which is divided into a rectangle or square, and has a plurality of perforations on the cover body, forming a streamlined head at both ends.

5. When the air flow passes through the gap between two adjacent mufflers, the volume of noise absorption will increase.

6. Some muffler column hole to form air flow channel, one end of the air guide wedge.

7. The surface of the perforated sound barrier can be treated differently, such as spraying, galvanizing, etc., with good aesthetics.

8. It is widely used in urban roads, factories, construction sites and other places with serious noise pollution.

What kinds of sound-absorbing materials do muffler columns have?

In 2024, there are many kinds of sound absorption materials for the silencer column commonly used in urban roads and other places. The common porous materials are mineral wool, glass wool, felt, wood wire sound absorption board and so on. This kind of material has good medium and high frequency absorption capacity, and can also absorb low frequency when there is air layer behind it. Perforated plate resonant sound absorption structure, such as perforated plywood, perforated fiber cement board, perforated paper plasterboard, perforated metal plate, etc., generally absorbs medium frequency, and absorbs medium and high frequency by binding energy with porous materials, and can also absorb low frequency with large cavity behind. Film sound absorption structure, such as plastic film, canvas, leather and other films are medium frequency sound absorption materials. In addition, there are sound insulation damping felt, polyurethane foam, sound insulation felt, sponge, insulating glass, sound insulation sound-absorbing cotton and so on. Sound-absorbing cotton is often used in interior decoration, with good sound-absorbing performance; Sound absorption board is widely used in construction, automobile and other industries, with high sound absorption coefficient; Sound absorbing coating is suitable for all kinds of surfaces, with good sound absorbing effect; Sound-absorbing wallpaper is also a common choice.

What is the influence of the column structure of the muffling column on the muffling effect?

The muffler column is usually a column structure, which has many influences on its muffler effect. First of all, the shape of the column makes it more reasonable in the spatial layout, which can be arranged in a display type within the frame, increasing the distribution density of the muffler column, thus improving the overall absorption and blocking ability of noise. Secondly, the column structure provides stable support for the internal sound-absorbing material, ensures the integrity and effectiveness of the sound-absorbing material, and helps to give full play to the role of the sound-absorbing material in absorbing noise and reducing its propagation distance. Moreover, some of the muffler column holes form air flow channel, one end of the air guide wedge, the design of the air flow channel in the column structure is helpful to guide the noise air flow, so that it is more effectively absorbed and processed by the muffler material. In addition, the easy disassembly and assembly connection structure between the end of the muffler column and the column also provides convenience for its installation and maintenance in practical application, and ensures that the muffler column can play a long-term and stable muffler role.
