Roman Ingarden’s work is widely taken as promoting a philosophical anthropology in which considerations from philosophy of ecology, that is, ecophilosophy, have no secure place. I think this contention is too hasty, even though Ingarden himself did not undertake reflections on the responsibility of humans for their natural environment. It is true that here and there he was giving explicit expression to his conviction of the unimportance of biological origins of humans, and was putting a strong emphasis on culture and other intentional creatures of humanity. In my paper I have tried to trace and describe Ingardenian understanding of humans in relation to their environment, and especially to nature. I have made an attempt to show how free human actions are possible, which in turn enforces on humans some responsibility for their actions, including those that impinge upon the nature around them.

Profile Analysis (PA) is a research approach developed by David M. Green and his associates, aimed at measuring listeners’ ability to discern changes in the spectral envelope shape of complex tones. PA introduces an innovative method by separating across-frequency spectral envelope shape comparisons within a complex tone and across-time level comparisons within specific frequency channels. This paper revisits the outcomes of several PA studies and examines the correlations between PA and the results obtained from experiments involving harmonic signals and listening tests designed to enhance timbre evaluation skills among sound engineering students at the Chopin University of Music in Warsaw.
