Puppies are born deaf, but their ability to hear quickly surpasses that of humans, as they grow into maturity. Dogs are able to hear within a frequency range of 67 to 45,000 hertz (cycles per second), which means they can hear ultra-high pitch sounds; this is something that human ears are unable to recognize. Humans are only able to hear a frequency range of 64 to 23,000 hertz. However, the sense of hearing gradually deteriorates in both dogs and humans as an age-related change.
