Road traffic ventilation and sound insulation barrier

180° barrier ventilation and sound insulation, full-band control of different types of road traffic noise

 

There are many types of road traffic noise, covering noise in different frequency bands of high, medium and low frequencies. Traditional sound insulation measures use sound insulation panels. On the one hand, it cannot achieve effective sound insulation against low-frequency noises such as whistles and engine noises. On the other hand, high-rise residents near the road have high-rise buildings near the road due to sound insulation. The panels failed to insulate effectively and were affected by various noises for a long time. A more scientific noise control plan was needed to resolve conflicts between the road transportation department and nearby residents.

Project sound insulation analysis

 

Road traffic noise is mainly low-frequency noise, and traditional sound insulation materials have little noise reduction effect.


The noise in road traffic mainly comes from car engines and whistles. As the main component of road traffic noise, car engine noise is a low-frequency noise. Due to the shortcomings of traditional sound insulation materials in low-frequency noise reduction, nearby residents still cannot get rid of car engines. The pain of waiting for low-frequency noise.

 

 

Traditional sound insulation materials fail to relieve high-rise residents from the pain of noise


Traditional sound insulation materials use sound insulation panels on both sides of the road to reduce noise, which can only reduce the impact of road traffic noise on low-rise residents. Residents on high floors are still exposed to the coverage of traffic noise.

Solutions

 

Noise reduction in high, medium and low frequency bands, effectively shielding various noises in road traffic

 

In view of the high, medium and low frequency noise of road traffic, combined with the volume of noise from different vehicles on the road, a module combination of ventilation sound isolators in different frequency bands is implemented to achieve full-band noise reduction and effectively shield various noises in road traffic.

 

 

180-degree full-angle noise reduction to achieve all-round shielding of road traffic noise

 

Lingbo Yisheng ventilation sound insulators are used to install tunnel-type roads to achieve 180° full-angle noise reduction of traffic noise. No matter how high the floor is, there is no need to worry about the noise impact.

 

 

Large area ventilation ratio meets the dual requirements of noise reduction and vehicle exhaust emissions

 

The ventilation area ratio of the ventilation and sound isolator module is as high as 50%. Under the condition of 180-degree full-angle noise reduction, it can still meet the real-time emission of vehicle exhaust gas in the soundproof tunnel, eliminating potential traffic safety hazards caused by a large amount of vehicle exhaust gas remaining in the tunnel and causing the driver to become comatose.
