Our application generates a sound wave that starts at 15 kHz and gradually increases by 400 Hz every 10 seconds until it reaches 22 kHz when the automatic option is selected. Once it reaches 22 kHz, it then gradually decreases back to 15 kHz before starting the cycle again. This oscillating frequency pattern is designed to effectively repel both dogs and mosquitoes. Users also have the option to manually select a frequency within this range for continuous emission, especially when targeting dogs. However, it's important to emphasize that the application may not always yield positive results and may not be effective in every scenario. Factors such as individual animal sensitivity and environmental conditions can influence its effectiveness.
