Spatial Noise Modeling in Dairy Operations

A prototype sound monitoring and evaluation system was used to measure the noise level in a medium-sized dairy barn. In addition, distribution of from shelter also modeled order determine how much barn, where only animals, mechanical tools working workers barn were source, affect neighboring operations terms intensity. Considering that intensity fluctuates according activities during day, equal (Leq), which is cumulative indicator, used. The data recorded by 7 sensors placed inside separately for day night conditions CadnaA software, Leq values both outside numerically visually. As result modeling study, levels determined averaging sensors. Accordingly, calculated as 69.0 64.2 dB, respectively. It these considerably lower than maximum allowable cattle. spatial emitted this establishment at would not cause disturbance operations.
