Assessment of the noise emission of sheep shearing systems
There is concern in New Zealand over the growing number of new cases of noise-induced hearing loss amongst sheep shearers each year. The sound pressure level in the woolsheds where the sheep shearing takes place can be in excess of 97 dBA,
due in part to the noise emission of the shearing systems used to shear the sheep. The purpose of this study was to benchmark the noise emission of sheep shearing systems inclusive of the shearing plant, the down tube and the hand piece. In addition, the sources of the noise emission were
identified using narrow band data and sound intensity mapping to focus future efforts at reducing the noise emission of the shearing systems.
