Sound has a range in time, frequency (Hz) and loudness or intensity whenever vibrating things generate changes in air pressure (decibels, sound pressure level). Comparative to humans, the ability of experimental animals to sense sound varies substantially by species. For instance, human hearing ranges from 20 Hz to 20 kHz, whereas rodent species have a far wider range of hearing ranges. We have designed a model that can generate ultrasonic frequencies to repel wild animals from crop land. We have taken observations for analyzing the impact of ultrasonic sound on animals for repelling them away from the crop-field. We have tried to find out that whether this model is sufficient enough to repel the animals or not.Therefore we have tested by increasing the frequency of ultrasonic sensor and analyze the result for predicting the impact of ultrasonic sensor on those animals.
