Frost fans have become an essential part of agriculture in areas subject to frosts, including vineyards, avocado farms and orchards.
Frost farms operate on limited occasions throughout the year. When they operate, they generally operate during the night, therefore protection against sleep disturbance is a critical component of the design.
Sonus has conducted assessments of the noise from more than 100 frost control fans around Australia considering the different criteria applicable in each state.
