Acoustic Indicators in the Analysis of the Acoustic Environment of the Koscieliska Valley in the Tatra National Park

The development of our civilization and increasing noise pollution are strongly connected. In 2021, the Tatra National Park was visited by a record number of tourists – about 4 million 600 thousand. The previous record was broken in 2018 – then the Polish Tatra Mountains were visited by 3 million 800 thousand. people. The aim of the paper is the analysis of noise pollution and soundscape of the most popular national park in Poland – Tatra National Park. The Koscieliska Valley was selected for the study, because it is the second area in the park in terms of the number of tickets sold according to the statistics kept by the Tatra National Park. The paper presents the results of the analysis of acoustic measurements and ambisonic recordings made during four seasons using classical method and the soundscape method. In addition, psychoacoustic parameters and soundecology indicators such as: loudness, sharpness or roughness, ACI (acoustic complexity index), NDSI (normalized difference soundscape index), BIO (bioacoustic index), ADI (acoustic diversity index), AEI (acoustic evenness index) were calculated.
