1 DEVICE DESCRIPTION AND OPERATION
1.1. Device purpose
1.1.1 The device is an acoustic bird repeller designed for protection of agricultural facilities (crops,
grain fields, vineyards, gardens), air fields, fishing vessels, etc. against birds.
Most birds (sparrows, starlings, blackbirds) bring serious harm to gardeners, winegrowers and farmers
damaging the significant part of crops during the harvest season. At the same time, during the nesting
period they kill a huge number of plant pests, so the complete elimination of birds is not acceptable.
The operating principle is based on the birds’ instinctive reaction to loud sounds. The sound brings no
physical damage to birds, but it scares them away and makes them escape the area.
Propane gas is supplied from a gas tank to a combustion chamber, where the spark plug ignites it and
causes a shot. The cannon significantly enhances the sound and the sound pressure level reaches 130 dB.
