Opis:: The problem of low-frequency acoustic waves emitted by wind turbine farms has become a great challenge to acousticians in Europe for more than 20 years. In Poland wind farm industry is growing rapidly and generates questions about the influence of such sounds on human organism. A short survey of previously published reports concerning subjectively perceived influence of wind turbines on people living next to wind farms is given together with the results of the Thayer's test measuring the difference in activation level before and after exposition on infrasound wave generated by a wind turbine. Statistically significant increase of the High Activation Level representing a tension type arousal has been revealed.

Opis:: The quietness, defined as the near or complete absence of sound, in the context of the natural environment protection, may be considered a state in which no undesired of foreign sounds occur, and, by analogy to noise, analyzed in two aspects: that pertaining to measurements and the subjective one. The article discusses the lowest levels of sounds recorded at night in the soundscape of the Białowieża Forest. Due to low levels of the examined sounds and the technical problems that occurred while the sounds were being measured and registered, the acoustic examination of the measurement set-up in an anechoic chamber has also been presented. The research is aimed at defining precisely the concept of quietness prevailing in the nature in the subjective aspect by determining both the range of levels and the characteristics of preferred sounds.
