It’s no secret that dogs are ultra sensitive to high pitch sounds. The high-pitch limit of human hearing cuts off around 20 kilo-hertz. For dogs, that boundary is up to 65 kilo-hertz. A dog’s hearing is so good that they can hear crystal oscillators inside of phones, computers, and electronic clocks.
A dog’s sensitivity to sound can be hundreds of times more sensitive to that of our own. That’s why loud noises such as fireworks, gunshots, or even all of the loud barking inside of an animal shelter can cause long-term harm.
