Simply put: much better, than us, humans. And cats even hear much better than dogs. But from experience, I can say, that it also depends on what and whom they want to listen to. How is it with dogs?
The possibilities of dog hearing change with the growing age as in case of humans. The older the dog is, the worse they can usually hear. In extreme case, some may lose their hearing almost completely in old age. However, in comparison with us, humans, dogs can hear much better. It is usually stated that at minimum, they can hear 2x – 3x better than us.
What does it mean in practice? For example, a silent sound, that the human ear is capable of hearing at the distance of 6 metres, the dog can hear even from the distance of 20 metres and more. That’s why, dogs that have the tendency to bark at incoming visitors, may sometimes start barking already when the visitor is only approaching your front door and we don’t see them, or hear them yet. A dog can even recognize according to the sounds of steps, whether a person known to them is coming to the house or someone unfamiliar.
The frequency range of dog hearing is also significantly wider than the human hearing. Dogs can usually hear sound with frequency of 40 Hz – 45 000 (sometimes, even 60 000 Hz is mentioned). For people, the maximum limit of audibility for the highest sound is usually said to be about 20 000 Hz. This means, that in comparison with people, dogs hear even such high sounds that our ear won’t notice. This is the principle of functioning of the well-known training high-frequency whistles. Their high pitched sound is even more audible to dogs for a longer distance to dogs than a human voice.
Moreover, in hearing, the dogs get help from their auricles which are movable and they direct the incoming sound waves into the ear canal.
And how do the cats hear?
Same as dogs, cats are able to turn their auricles using small muscles so that the sound penetrates their ear canals at the best angle possible. Cats even have much more of these small muscles around the auricle, and that’s why they are able to work with their ears with a much greater accuracy. Even in case of the upper audibility limit of sound frequencies, cats surpass dogs. It is said, that cats are able to hear even sounds with the frequency of 64 000 Hz.
Since it is easier for cats to decode the sound when they are not in motion, you can notice, that if they catch a sound that is interesting for them, they usually stop, and sometimes, it almost seems as if they’ve turned to stone.
And one more tidbit at the end: hereditary deafness often in dogs and cats goes along with white hair colour. In case of cats which are white and have one blue eye and the other yellow for instance, the ear that’s on the same side as the blue eye is frequently affected by deafness. This type of deafness is related to pigment cells called melanocytes. Since these are formed from the same base as the cells in the interior part of the ear. If melanocytes don’t function correctly, the result is white colour. Moreover, there’s an increased probability that even some cells precisely in the inner ear will develop incorrectly and as a result, the animal will be white … and deaf.
Although it might appear that the cat doesn’t give a tail about you and it is indifferent towards you, maybe you will still find some displays of affection in its behaviour. Do you know how cats show such affection towards a person?
Cats love grass. They nibble at it if it's to clean their belly from hairs or just for fun. In addition, if you get a cat its own flowerpot, you can hope that it will leave your other plants alone :).
Whether you remove a tick from a dog’s or cat’s fur the right way might affect whether the animal will become infected with Lyme disease or another malign disease transmitted by ticks. Have you got the right technique and tools?
Just like with people, also in dogs, Lyme disease is a very grave illness. There are an estimated 20% of ticks infected in the Czech Republic. And because despite the use of antiparasitic agents, your dog might get a tick from time to time, it’s good...
I’ve already written about cat mint, today, we’ll take a look at another, lesser known drugs. Since not all the cats respond to all of them and they don’t respond to everything the same way. Therefore, if you didn’t succeed with cat mint, maybe you’ll...
Every cat owner has certainly already heard of cat mint, catnip or catswort. Under all these names hides a herb that makes most of the cats “high”.
When your family grows by a new (human) member, it isn’t necessarily a happy event for everyone. For many dogs, it’s very difficult to come to terms with such situation, therefore, it’s better to start preparing them already before the baby is born....
I’ve already written about the fact that you’re not supposed to leave your dog closed in a car on summer days or on how to prevent hyperthermia in cats and dogs. So you have mastered the prevention already. But it is also necessary to know how to...
Without a question, chinchillas are beautiful and cute furry animals with large ears, a long tail and distinctive eyes. Do you know where they actually come from, what their name means and that we almost succeeded in nearly exterminating them before...
You have probably noticed that cat tongues are quite unique. They are rough and somehow scratchy. It seemed weird to American biologists and therefore they decided to look deeper into it.
What should I say, the cats are simply different. Since the time immemorial, they have been surrounded by mysteries and secrets. Most of them behave as if they were the master of the world and as if they don’t need the human at all. A couple of...
It can be quite a task to choose the right pet food precisely for your cat. To even understand the contents... That’s why we’re going to take a look today what to focus on, what to look for in the contents and what you should rather avoid.
