The sound barrier refers to a wall-type structure arranged beside a railway and a highway for reducing the influence of driving noise on nearby residents, and is mainly used for sound insulation and noise reduction of the highway, the expressway, an elevated compound road and other noise sources. Outdoor sound barriers are generally of brick or concrete structures, and indoor sound barriers are of steel plate, wood plate, plastic plate, gypsum board, foamed aluminum and other structures. The sound barrier mainly comprises two parts, namely a steel structure upright post and a sound absorption and insulation screen board, wherein the upright post is a main stressed member of the sound barrier and is fixed on a road anti-collision wall or an embedded steel plate at the edge of a track through bolts or welding; the sound absorption and insulation board is a main sound insulation and absorption component and is fixed in the H-shaped upright post groove through a high-strength spring clip to form a sound barrier. Sound barriers are currently in wide use.

Noise pollution has considerable harm to life and health of people, and the source of noise is very wide. Noise is also a potential source of energy with a considerable amount of energy, such as car noise, for example. In order to recycle the energy, a sound energy power generation device can be adopted to convert the sound energy in the environment into electric energy, so that the noise in the environment can be effectively reduced, the environment can be protected, and the noise pollution can be changed into resources to be effectively utilized. The current sound barriers eliminate the sound energy mainly by sound absorption, and there is no consideration for noise reduction from the aspect of sound energy recycling, and there is no corresponding device design, which may be associated with excessive costs due to the mere transduction of the sound energy.
