Influence of selected factors on sound levels inside and outside of pig barns

Original language description

The aim of this study was to investigate a potential impact on the formation and propagation of sound from pig barns. We tested a hypothesis that the sound generated from pig housing would be influenced by the measuring distance from the barn (up to 11 m), time of day relative to feeding, building side direction, and season of year. The research was carried out in a barn for 1728 fattening pigs in the summer and winter. The measurements were made inside and outside the barn. The data were recorded before feeding (BF), during feeding (FE), and after feeding (AF). Sound levels were significantly influenced by the time of day (P<0.001) and measuring distance (P<0.001). The highest values were found inside the building at feeding time (71.95+-1.41 dB). The impact of the building side direction on noise propagation through the wind was confirmed (P<0.001). The highest levels of sound were measured outside in direction to west and south sides in both, 7 m (49.40+-3.79 dB, 47.58+-4.31 dB), and 11 m (48.54+-3.63 dB, 48.97+-4.10 dB) distances. Sound levels during the summer were significantly higher (P<0.05) than during winter. The results indicated that sound emitted from the pig housing is dependent on the distance from the building, time of day, building side direction, and the season of year. In the surroundings of the building, the dependences of sound on wind direction were found. The results of this project are specific to the barn and environmental conditions under study, but they do provide insight into the relative importance of these factors for future studies.
