How does the product work?

Deter nuisance barking with an ornamental touch! When the device is within range of continuous barking, an internal microphone picks up the sound and the unit is activated. The device emits an annoying tone that only works for dogs, the dog should stop barking, as it will correlate its bark with an unpleasant noise. The average human hearing frequency ranges from 20HZ~20KHZ, while dogs can hear from 15HZ~120KHZ, so the device is only useful for normal dogs, not for ear illness ones. Remember to give your pet the appropriate reward when it stops barking so that it relates the ultrasonic frequency with your desire to have it stop barking.
When working on 3 different levels, the light will flash blue every 6s; Red light stays on 3s when the sonic bark deterrent is triggered by barking; the red light will flash when in low power.
