The present invention relates to a dry intake material soundproofing wall installed on the road for soundproofing. More specifically, the soundproof panel is made of recycled waste plastic and solid waste, which is harmless to the human body, environmentally friendly, and various designs are possible. Due to the material characteristics of the panel, it is simple to manufacture, the construction period is short, and the site construction is easy.

In general, people living in the area around the road are greatly affected by the noise caused by the vehicle driving on the road. Therefore, in most countries, there are provisions for the noise in the area around the road to be below a certain limit, and when designing a road according to such a rule, a soundproof wall for noise prevention is usually installed. There are various kinds of sound barriers in the form of reflection type, sound absorption type and the like.

Reflective sound barriers are not installed to reduce noise generated by installing on one side of the noise source, but reflect the noise so that it does not progress in a certain direction. It is easy to install and maintain, but the sound insulation effect is low to satisfy the required noise standard. it's difficult.

Sound-absorbing sound barriers are widely used as a way to reduce noise itself by absorbing noise, and are generally manufactured in the form of a sound absorbing material inserted into an aluminum structure.
