Here's a breakdown of the differences:
* Humans: Can hear frequencies between 20 Hz and 20,000 Hz.
* Dogs: Can hear frequencies between 40 Hz and 60,000 Hz.
This means that dogs can hear sounds as low as a very deep rumble, but also sounds as high as a very high-pitched whistle.
Here are some examples of sounds dogs can hear that humans can't:
* Ultrasonic frequencies: These are sounds above the range of human hearing. Some examples include:
* Ultrasonic dog whistles: These whistles emit a sound that is too high for humans to hear, but dogs can hear it easily.
* Ultrasonic rodent repellents: These devices emit ultrasonic sounds that are meant to deter rodents, but humans can't hear them.
* Very low frequency sounds: These sounds are below the range of human hearing. Some examples include:
* Subsonic sounds from earthquakes: Dogs may be able to sense and hear these sounds before they are felt by humans.
* The sound of a distant thunderstorm: While we may only hear the thunder, dogs can often hear the rumbling of the storm from much further away.
It's important to note that the exact range of hearing can vary between different dog breeds.
The ability to hear a wider range of sounds is one of the reasons why dogs are so good at detecting danger. They can pick up on sounds that we might miss, which allows them to alert us to potential threats.
