“…In this study, this situation occurs on a sample h=25 mm at 1000 Hz with a sound absorption coefficient of 0.88. This value is higher than the previous measurement value published by [6] for samples of plants such as Ficus pumila and Vernonia Eliptica with similar thicknesses due to the characteristics of thicker and wider leaves.…”

“…The top side of the TZ leaf ranges from green to purple and features two broad, silvery-white stripes, whereas the underside of the leaf is consistently deep magenta in color [5]. In previous research by [6], other creeping plants of Ficus Pumila and Vernonia Elliptica produced encouraging results in absorbing sound. Vernonia Elliptica and Ficus pumila produced maximum sound absorption at 800 Hz with 0.78 and 0.73, respectively.…”

The increasing need to address the environmental consequences of noise and visual pollution caused by infrastructure and industrial projects in residential regions has led to the implementation of regulations. These regulations aim to minimize such impacts and have resulted in a rising demand for acoustic barriers and visual screening solutions. Presently, green plants are being employed globally not only for creating a sustainable environment within green buildings but also for their sound absorption capabilities. The choice of plants suitable for green walls primarily focuses on tropical and annual species that demonstrate effortless growth capabilities. This research examines the capability of sound absorption of chosen creeping plants namely Tradescantia Zebrina (TZ) that potentially be used for green facades. The physical properties including morphology and acoustical properties by measuring the sound absorption coefficient (SAC) using two microphone impedance tubes. The plant with the noise reduction coefficient (NRC) was investigated further for the effect of the thickness of the plant on the sound absorption performance of a wall. The results showed 0.23, 0.35, and 0.52 NRC values respectively obtained from the different thicknesses of TZ There was an increment of sound absorption as the plants were attached to concrete brick as a green facade on its surface. On this basis, the capability to absorb sound by TZ as the green facade can be considered when designing the environmental structure.
