Abstract
The I-Kaboom system was developed as a deterrent for birds and monkeys in agricultural regions, focusing on optimising sound pressure levels to achieve effective deterrence. This study systematically analysed the sound pressure levels produced by varying gas pressures, with parameters chosen based on their performance prior to performance testing and data collection. The pressure parameters ranged from 1 bar to 1.57 bar, identified as the optimal range for effective deterrence. It was observed that lower pressures resulted in effective sound levels, while higher pressures produced damped sounds unsuitable for wildlife deterrence. High-pitched sounds were found to be the most effective. The optimal parameter, identified as parameter 2, produced a sound pressure level of 112.1 dB (A) with a filling time of 2 seconds and a pressure of 1.14 bar, demonstrating high-pitched and effective deterrence. Additionally, parameter 19, with a filling time of 3 seconds and a pressure of 1.4286 bar, showed stable sound pressure levels with the lowest standard deviation of 1.0716, according to one-way analysis of variance (ANOVA). Despite producing a slightly lower maximum sound pressure level of 107.1 dB (A), parameter 19's stability and reasonable sound pressure range were identified as optimal for the propane cannon's best performance. The findings emphasise the importance of optimising gas pressure and filling time to achieve effective and consistent sound pressure levels for wildlife deterrence.
