WFS Protect 

Acoustic precaution is a method that influences the human body through sounds of specific frequencies and intensities, thereby guiding and controlling human behaviors. “Acoustic precaution” equipment is a NLW and also an efficient intense sound publicity and command system. In the fields of police and safety emergency, it can achieve the usage effects of being clearly audible, mobilizing easily and controlling firmly. Besides enabling sound to play the role of publicity, it can also exert the management and control function in the ways of dispersing.

AND TRAFFIC SAFETY

Vehicles, boats and pedestrians passing on various roads, waters and bridges often lack sufficient early warning mechanism protection. With insufficient anticipation of potential dangers ahead, drivers can easily get into dangerous situations without being aware. Especially under the influence of bad weather, the probability of traffic accidents increases significantly. It also makes accident handling more difficult, prolongs the rescue time and raises the probability of secondary accidents.

Directional sound intensifiers and acoustic precaution systems can efficiently realize rapid handling and timely intervention of traffic accidents on expressways, issue warnings and dynamic warning information in bad and extreme weather, and perform various road reminder functions such as anti-fatigue driving reminders and other safety warnings. Transmitting warning information to each driver in a simple, quick and effective way is an important symbol of the informatization, intelligence and digitalization construction of expressways.

Create all-round and integrated "acoustic precaution" solutions for traffic safety command and early warning.

Enabling ultra-long-distance safety early warnings and instantly alarming the safe following distance between cars.

Intense sound waves penetrate car windows and give a compulsory warning.

Under the current standard, the layout requirement of expressway sound amplification equipment is to install one set ordinary amplification equipment every 50 meters, which fails to achieve the purpose of remotely warning and reminding

Precisiond irection alsound amplification technology significantly reduces sound refraction and reflection in tunnels, and the highdefinition audio transmission mode ensures clear and smooth sound quality.

Intunnels,thesoundsof multiple loudspeakers have different delays. Coupled with severe sound refraction and reflection in the semi-enclosed space, multiple sounds overlap, resulting in sound reverberation and finally making the sound heard by drivers and passengers

Solutions of Acoustic Precaution

Vehicle-mounted early warning systems can issue emergency safety prompts on-site along with traffic safety and roadad mini stration vehicles. Portable devices can also be carried by staff to the site to issue intense sound warnings.

dslides, falling rocks, collapses and various traffic accidents occur from time to time. If there is a lack of emergency warning measures in the surrounding area, new traffic accidents are extremely likely to happen.

Solutions of Acoustic Precaution

warning system for traffic safety can independently issue emergenc y safety prompts for sections with bad weather,avoiding the occurrence of accidents.

Rain and foggy weather severely impairs the vision of drivers and passengers. Likewise, snowy and icy weather leads to icy road surfaces. Without remote warning and command measures, the probability of traffic accidents is extremely high.

Solutions of Acoustic Precaution

Directional narrow-angle sound amplification technology ensures that the audio transmitted by the sound intensifiers can be confined within a specific lane, without sound spillover, misdirection, or disturbance to residents.

Traditional sound amplification equipment generally emits spherical sound wave. On expressway sections close to residential areas, the sound often spills over into the residential areas, causing noise interference to local residents.
