Happy Mother's Day

On May 4th, our company held a Mother's Day celebration to further promote traditional Chinese virtues, celebrate the greatness of maternal love, and express gratitude to mothers. Our company organized a health check-up activity in Shijiazhuang for our outstanding employees, and smiles could be seen on every parent's face. 萱草生堂阶，游子行天涯；慈母依堂前，不见萱草花。 慈母手中线，游子身上衣。临行密密缝，意恐迟迟归。谁言寸草心，报得三春晖。

Basic knowledge of noise barriers

A noise barrier is a device placed between a sound source and a receiver to significantly reduce the propagation of sound waves at the receiver's location, thereby mitigating noise pollution.

How to choose a high-speed rail noise barrier? What kind is good?

Railway noise barriers (trackside noise barriers) are noise barriers used on both sides of railways and high-speed railways to reduce noise pollution caused by passing trains to nearby residents.

Factory area noise barrier manufacturer

The higher the density of the factory area sound barrier, the better the sound insulation effect. 1. High sound insulation: The average sound absorption should not be less than 35dB; 2. High sound absorption coefficient: The average sound absorption coefficient should not be less than 0. Hollow bricks and aerated blocks with holes generally have good sound insulation effects due to their increased surface area; of course, there are also sound-absorbing cotton felts and the like. Sound barriers, also known as baffles, are commonly called sound screens. Mine sound barriers, mine sound barrier construction cost and manufacturer price. It can be nailed or glued. Perlite fireproof board: Perlite board, floating bead board, and vermiculite board are hollow plate materials made with low-alkali cement as the base material, perlite, glass microbeads, and vermiculite as aerated filling materials, and some composite materials added. They are characterized by light weight, high strength, good toughness, fire prevention and heat insulation, and convenient construction, and their processing technology is simple. It has the advantages of low investment, fast construction speed, and obvious landscape effect. The cooling tower sound barrier is a combination of assembled modules that can be assembled arbitrarily, durable, and easy to install and maintain. Cooling tower sound barriers are increasingly recognized by some residential areas and office buildings, and they can greatly reduce some of the noise in our lives.

What are the main features and hidden functions of highway noise barriers?

Highways are the most common places to use noise barriers, and their main features are as follows: 1. Flexible and convenient installation and use. Noise barriers are mostly designed in a modular way, so they are very easy to disassemble and install. 2. Powerful function: The noise barriers on both sides of the highway have good sound absorption and sound insulation effects, and also have good durability, and can be used for many years. 3. Good sound insulation effect. The average sound insulation of noise barriers is about 36dB, and the average sound absorption coefficient is high, maintaining around 0.83.

Several key elements for installing highway noise barriers?

Road environment is an important part of the urban environment. The three major spaces of a city, namely traffic space, building space, and open space, and the relationship between the elements of each space play a decisive role in the urban environment. Roads are a city's corridors and showcases, the main places where people understand and experience the city. The linear environmental characteristics of roads directly reflect the city's appearance and personality. Therefore, the landscape design of noise barriers should conform to the characteristics of the city's appearance, consider people's visual feelings, reduce the sense of oppression while meeting the noise reduction function, strive for coordination between the noise barrier and the main project and the surrounding landscape, reflect the rhythmic beauty of the noise barrier project, and enable road users to obtain psychological comfort, so that the noise barrier project can also become a beautiful landscape. In the specific design, methods such as three-dimensional modeling layout, pattern combination, material selection, color matching, and plant landscaping can be used to meet the needs of most viewers.

What factors influence the design of noise barriers to improve sound attenuation?

Many factors affect the insertion loss of a noise barrier, such as its relative position, height, and shape. Highway noise barriers have various names and different materials.

Applicability of highway noise barriers

The construction and operation of highways have driven rapid regional economic development, but have also brought noise pollution to sensitive areas such as residents, schools, and hospitals along the route. Noise barriers, due to their characteristics of occupying less space and significantly reducing noise, have been widely used on highways. However, most designs are extremely unreasonable, with arbitrary and blind choices in noise barrier design, selection, and material construction.
