Design Consideration of a Noise Barrier

According to EPD guidelines, the main function of the sound insulation wall is to eliminate excessive noise generated from the vehicle. Soundproof walls are considered to be the most reasonable and effective soundproofing measures. There are many factors to consider when designing soundproof walls. They include acoustical design considerations, transmission losses of various barrier materials, noise barrier properties due to holes, slits or gaps, barrier shapes, material selection, barrier materials, ground protection and retention structures, and non-acoustical considerations .

Improvement of urban planning and road design will reduce road noise and other urban factors. Reducing road noise by using sound barrier, speed limit of car, change of texture of road surface, limitation of heavy car, brake operation by smooth car flow, accelerated traffic control, and tire design I can do it. An important factor in applying these strategies is the computer model of road noise, which deals with region topography, meteorology, traffic management, and virtual relaxation issues. If these solutions are required at the planning stage of the road project, the relaxation cost of the building may not be so high.

The visual system, the auditory system, and the kinesthetic system are three important meanings in the work design. The noise is dangerous and troublesome. High noise can cause permanent hearing loss. Noise can also be an impediment to effective communication. The best way to control ambient noise is to isolate the user from noise sources. Noise can also be reduced by using soundproof screen and sound absorbing ceiling material. Like a person using a road rig, many people use electric motors to give vibration to their hands. In addition, vibration is divided into "vibration of arm" and "vibration of body". When exposed to the vibration of the arm excessively, "vibrating white finger" is displayed. Schedule designed to use damp vibration combinations of hand tools, warm and dry gloves in cold and humid places, and shorten daily exposure time

The first big obstacle to noise communication is noise. Noise generated by communication at the transmission level is distorted. The meaning of the term "noise" in the field of communication comes from the field of physics. In physics, noise means "interference, especially random and continuous interference that may blur or lower the clarity of the signal." As you can see from the use of computer science, the modern meaning of the word "noise" is "irrelevant or meaningless data". For example, traffic noise around schools hinders the flow of information between teachers and students. This makes verbal communication difficult. Likewise, a signal or static electricity reduction when talking on a cell phone, using a public address system, or watching TV may also distort the voice signal and interfere with communication Yes.
