Effective Ultrasonic Dog Repeller: Works or Not?

How Ultrasonic Dog Repellers Work:

When used correctly, an ultrasonic dog repeller emits a powerful ultrasonic sound that is only audible to animals, not to humans. This sound, with an intensity of approximately 125dB at a distance of 30cm, can cause discomfort and intolerable interference for animals. As the piercing sound gets closer to the animal, the discomfort intensifies.

Operating an ultrasonic dog repeller is straightforward. Simply aim the ultrasonic speaker at the approaching animal and press the switch to emit the unpleasant sound that will deter it. Since the sound intensity decreases as it moves away from the direction of emission, focusing the repeller continuously on the animal for better results is recommended. This device is an ideal choice for outdoor enthusiasts, cyclists, and travelers who wish to avoid unwanted dog disturbances.

Generally, infrasound is a type of sound that humans cannot hear, with frequencies below 20Hz. However, dogs, with their highly sensitive hearing, can detect these sounds. A dog's hearing is about 16 times more acute than a human's, allowing them to clearly hear sounds ranging from 16 to 50,000 Hz.

Like ultrasonic sound, infrasound can stimulate and startle dogs immediately upon release, causing them to feel fear and instinctively flee. Compared to ultrasonic sound, infrasound has a longer effective range and is less likely to dissipate over distance.
