title = "AN INVESTIGATION ON THE VENTILATED NOISE BARRIER WITH LOW-FREQUENCY SOUND INSULATION ACOUSTIC METASURFACE",
abstract = "This paper explores the application of acoustic metasurface in the ventilated noise barrier. The proposed metasurface unit is composed of multiple sub-cavities, with an opening at the center to facilitate ventilation. This structural design aims to reduce sound propagation while ensuring fresh air circulation. Numerical simulation methods are employed to analyze the transmission loss of the metasurface and an infinite noise barrier. The coupling effects between the sub-cavities of the metasurface structure enable the ventilated metasurface to achieve low-frequency broadband sound insulation. Experimental studies conducted in an anechoic chamber demonstrated that within the human auditory frequency range, the acoustic metasurface results in the total OASPL reduce by 18.2 dBA. This work contributes to the development of innovative solutions for noise control in various environments, particularly in the conditions where both ventilation and sound insulation are crucial considerations.",
