Abstract
The work aims to investigate whether contemporary acoustic indicators can be applied to soundscape monitoring with a particular focus on the protection of enclaves of silence present in the urban environments. The study includes the following coefficients: acoustic complexity index (ACI), normalized difference soundscape index (NDSI), bioacoustic index (BI), acoustic diversity index (ADI), acoustic evenness index (AEI). As part of the work, a database of 90 sound recordings was created and subjectively divided into three groups: quiet places, places of entertainment and noisy places. At this stage, it was shown that the most common distinction was between recordings from quiet places and places of entertainment. For the BI coefficient, no group could be distinguished.
