Description

Technical Field of the Invention The present invention relates to a sound barrier (such as noise wall, sound wall) capable of high sound insulation and absorption. Due to its sound insulation and absorption capability, the barrier can be used in any area where noise pollution is present. The barrier contains both recycled waste carbon fiber mesh and end-of-life tires (ELT), which lowers its carbon footprint of the sound barrier. State of the Prior Art Pollution is an ever-growing threat of today's world. It is occurring in every single part of the world with several different types, such as noise, water, and light pollution. Noise pollution, like many other pollution types had increased, considerably over the last century and it is continuing to increase with each-coming year. Noise pollution (or sound pollution) mostly occurs in the big cities, around roads, railways, airports, entertainment venues, construction sites or industrial facilities. People who work or live arounds these places are subjected to a considerably high amount of noise pollution. This pollution negatively effects people physically and psychologically. Studies shows that noise pollutions can lead to high blood pressure, tinnitus and hearing loss. As psychological outcome of the noise pollution, stress, anxiety, sleep deprivation and aggression are commonly experienced. Moreover, it has been reported that animals and plants that are subjected to noise pollution over a certain amount of time, experience similar physical and psychological problems as well. The increase in the noise pollution, lead governments and private corporations to look for ways to decrease this pollution. To this end, over the years, silent engines etc. have been manufactured; however, noise primarily originates from the contact between tires and the surface of the road when vehicles exceed the speed of 30 km/h. Hence, people who are residing around highways and railways, are still subjected to noise pollution. For that matter constructional structures that prevents the pollutant noises to reach to the residences are being used. These structures can be listed as (but not restricted to) barriers, sound tubes, insulation glasses and so on. Among these structures the sound barriers are the most commonly used one since, they can be produced in desired sizes and shapes. However, they still fall short in certain aspects due to their reflective surface. In the prior art, EP22188805.0 patent application explains a sound barrier. This barrier contains styrene butadiene rubber (SBR), which is recycled from end-of-life tires. This decreases the carbon footprint of the barrier. While the barrier provides high insulation of noise, it fails to absorb it. This means that the noise is not removed from the environment but actually trapped between the source and the barrier. Although, this somewhat protects the people in the domestic areas, the people who is working or stationed near the sources (for example drivers) are still exposed to noise pollution. Hence, this sound barrier is not quite effective to be used as a precaution against noise pollution due to its low-to-no sound absorption. During the application to very large areas, due to the high reflective power of the sound barrier, the reflected sound will not have a significant impact on the area. However, as the application areas move into more urban areas, the reflected sound from the sound barrier may cause harm to other areas (for example, increasing the noise heard by houses on the opposite side of the road). Therefore, it is necessary to use not only a barrier with strong insulation but also one with sound absorption properties. The CN210216199U utility model application explains a composite sound absorption panel. The panel in question contains several layers; an aluminum foam layer, a first plastic material layer, a honeycomb aluminum layer, a second plastic material layer, and an ordinary aluminum layer. The panel claims to offer effective sound absorption; however, the use of foam aluminum material here increases the production cost and need for periodical checking, makes the production process quite complex and causes environmental pollution with high carbon footprint due the choice of materials used in the production. In the prior art, there are problems such as the barriers/panels offering low sound absorption and insulation, high-cost production, the need for periodical checks, usage of pollutant materials, complicated production methods, which made it necessary to make developments in this technical field. Brief Description and the Aims of the Invention The present invention is related to a sound barrier that is capable of high sound insulation and absorption, with low carbon footprint. The sound barrier contains recycled granule rubber, binder, catalyst, fire-retardant, waste carbon fiber mesh, absorbent low-density polyethylene (LDPE) foam and synthetic grass. The color of the sound barrier, LDPE foam and the s
