Evaluation of annoyance due to wind turbine noise based on pre-learned patterns

Felcyn Jan, Preis Anna, Gogol Robert

Vibrations in Physical Systems

2022

Vol. 33, nr 3

art. no. 2022310

Annoyance due to wind turbine noise is usually assessed on the basis of surveys conducted among people living in the vicinity of turbines or in the laboratory conditions. Due to the fact that the latter are very different from natural conditions, we propose a solution to reduce this difference. Prior to the surveys, 50 participants were asked to familiarize themselves with 5 environmental signals. They were informed about the annoyance rating assigned to each signal (obtained earlier in laboratory conditions), expressed as a number between 0 (not annoying signal) and 10 (extremely annoying signal). Participants were then presented with new environmental sounds and asked to rate the annoyance caused by each sound, in accordance with the previously learned method. The analysis of our results shows that the variability of answers given by respondents at their homes is similar to those obtained earlier in laboratory conditions.

Przedstawiono metody badań, nieniszczących i mało niszczących. Szczególną uwagę zwrócono na metodę badań opartą na wykorzystaniu próbek rdzeniowych pobieranych ze ścian i filarów murowych. Sformułowano wytyczne, które mogą być wykorzystane w praktyce.

Non-destructive and minor-destructive test methods were presented. Particular attention was paid to the testing methods based on the use of core samples collected from the masonry walls and pillars. Recommendations that can be useful in practice were formulated.
