Anping Chintai sound barrier panels

The scientific and technical indicators of the performance of sound barrier panels mainly include sound attenuation, the average sound absorption coefficient and sound insulation of the sound barrier, and the noise reduction cutoff frequency of the sound barrier.
The amount of sound attenuation is also the insertion loss, and its calculation method is that the amount of noise is affected by the amount of noise at the image point. For example, the speed of vehicles on viaducts is generally between 1 meter and the noise level one meter away from the roadside, and the noise at points affected by residents is generally between 1 meter and 1 meter. Therefore, the insertion loss after the construction of this sound barrier is above.
The average sound absorption coefficient and sound insulation amount of the sound barrier
The average sound absorption coefficient of the sound barrier. The sound absorption coefficient of the fully sound-absorbing components of the sound barrier. Average sound absorption coefficient ++ where, is the sound absorption part of the sound barrier, the sound absorption coefficient of the reflection part and other parts, and . is the area of the corresponding part.
The sound insulation amount Δ of the sound absorbing components of the sound barrier reflects the sound insulation Δ of the transparent film.
The bulk density of the porous material filled in the sound-absorbing component is /.
Noise reduction cutoff frequency of sound barrier
The barrier plate includes the mechanical properties, acoustic properties, structural requirements, component surface treatment, civil engineering, materials, and other requirements of the barrier body. The construction involves civil engineering and component production. and on-site installation, etc. It can be said that the highway sound barrier construction project has the characteristics of small but comprehensive. The sound insulation barrier has good sound insulation effect and can isolate high-noise equipment to separate the noise from the quiet. The sound barrier board has the characteristics of beautiful appearance, durability, easy installation, harmonious viewing effect and environment, etc. It is suitable for noise isolation of traffic noise, construction site noise and large industrial equipment.
