A bat deterrent system to deter bats from approaching wind turbines may include a first deterrent box having a first and second transducer bank. The first transducer bank may include a first set of transducers located on a first plane and a second set of transducers located on a second plane. The second plane may be different from the first plane. The bat deterrent system may also include a second deterrent box having a third and fourth transducer bank. The third transducer bank may include a third set of transducers located on a third plane and a fourth set of transducers located on a fourth plane. The fourth plane may be different from the third plane. At least one transducer may simultaneously emit a different ultrasonic output waveform than the ultrasonic output waveform emitted from another transducer.
