Abstract: In this paper, a landscape noise environmental assessment method based on life cycle assessment is designed. The audio features of landscape environment are extracted, the landscape noise is identified and processed by HSCW window function, the evaluation indexes of the three main stages of landscape life cycle are selected by LCA method, and the grey interval of the evaluation indexes is clustered to realise the noise environment evaluation. The experimental results show that the maximum accuracy of landscape noise monitoring can reach 96.4%, the minimum time-consuming of noise environment evaluation is 17.6 min, and the maximum evaluation accuracy can reach 96.9%, which is significantly higher than the two methods. It shows that this method has high noise monitoring accuracy, short evaluation time-consuming, high evaluation accuracy and good practical performance.

Keywords: life cycle assessment; LCA; landscape architecture; noise environment; noise assessment.
