Description

Soundscape analysis, using acoustic indices, provides researchers with valuable ecological information to assess biodiversity, species behavior, and noise pollution. In this study, to analyze biophonies and anthrophony in six urban parks in Isfahan city in spring, six acoustic indices, including Acoustic complexity index (ACI), Acoustic Diversity Index (ADI), Acoustic Evenness Index (AEI), and Bioacoustic Index (BI), Normalized Difference Soundscape Index (NDSI) and Entropy Index (H) were used and quantified using Seewave Package in R software. In the next step, using ANOVA test, we evaluated the significance of difference between values of the indices among the six parks. We also calculated the degree of correlation between pairs of the indices among and within the parks using Tukey test. According to the results of ANOVA and Tukey tests, the highest values of BI, NDSI, ACI, ADI, AEI and H indices were …
