The article presents the results of a study of the acoustic efficiency of a green facade formed with Parthenocissus quinquefolia as a natural noise-absorbing barrier in an urban environment. The relevance of the work is due to the growing level of noise pollution, which is one of the leading environmental risk factors in cities. The potential of vertical gardening as an element of sustainable architectural design that combines aesthetic appeal with environmental and functional benefits is investigated. The aim of the study was to quantify the ability of a green facade formed by Parthenocissus quinquefolia to reduce sound pressure levels in the external and internal environment of a residential building. The experimental part was carried out by means of full-scale modelling of a facade fragment in two seasonal states - with and without the existing leaf cover. Acoustic measurements were performed in accordance with the requirements of DSTU B V.2.6-86:2009 under controlled conditions. Additionally, numerical modelling of wave propagation was applied, taking into account changes in the effective density and elastic properties of the medium. The results of the study show that the leaves of Parthenocissus quinquefolia reduce the sound pressure level by up to 20 dB in the mid-frequency range. Even in the absence of leaf cover, a pronounced noise-protective effect is maintained, which confirms the feasibility of using this plant for vertical gardening in the context of reducing noise load. The obtained results deepen the understanding of the acoustic properties of green facades and emphasise the feasibility of their use in the environmentally oriented design of urban spaces.
