Measures have been introduced to reduce the health risk and nuisance of agricultural noise to humans. However, humans are not the only animals that can be affected by sound. The sounds to which farm animals are exposed are not controlled and furthermore are relatively unknown. This study was carried out to determine the sound experienced by pigs throughout their production. Recordings of noise were made at six farms, on five transporters and at four abattoirs. From these recordings, information extracted included averages and ranges of sound pressure levels, ranges of frequencies and peak frequencies and sources of the noise components. |
