I would say no.
I'm educated on the topic, but also biased as my family owns a business in the field. The frequencies of ultrasound aren't detectible by the human ear. You encounter frequencies that you can't hear all the time, you just don't know it ;)
They have special claws to hang when they sleep. They have ears to listen to ultrasound because they can't see.
It is too loud for my little ears!
so they can hear danger.
it is in groups and herds and there is usaully a stallion of the pack, which leads and looks for danger with it's ears and eyes.
They aide the lynx by helping them hear food and danger.
bats have bad eyesight so they use their echo ultrasound and big ears to reflect sound and tell if there is something in front of them so that they can see similar to how a cats wiskars work
because they could be sencing danger sted of hearing danger because then he knows hes safe
So that while lying down in the grass, they can still hear if danger approaches.
In the wild, the ears help them listen for predators and other dangers. For a pet, they don't matter much.
Yes dogs have ears and they have these great ears to hear from a mile or even 2 miles away. They use their ears to hear danger that might be coming their way.
Ears enable the wombat to hear. Like all wild animals, wombats need to be on the alert for danger. Being able to hear assists this.
The danger that they faced as a whole is that if they did not plug their ears as they did or if they were not tied to an unmovable object then they would be drawn into the ocean where they would slowly drown.
