The dog owned by my neighbor frequently barks loudly at night as it stays in their backyard continuously. A wooden fence separates our house from the neighbor's. Even after we tried to communicate politely, the neighbor doesn't appear to be genuinely concerned about resolving the dog barking issue. To address the problem, I attempted to acquire an anti-barking device that produces ultrasonic sound automatically when the dog barks. However, the device is ineffective due to the wooden fence that separates our houses, as the ultrasonic sound cannot penetrate it, according to the manufacturer's website.
Can an alternative anti-barking device be found that emits ultrasonic sound capable of penetrating a wooden fence?
