By looking at the image above, as well as the title of this post, you may assume that the larger the dog's ears, the better their hearing is. This correlation has no relation, I chose this picture solely because it's funny to look at.
Below are some facts on the difference between Human and Dog hearing:
- Humans can hear sounds approximately within the frequencies of 20 Hz and 20,000 Hz.
- Anything below 20 Hz, typically cannot be heard although it can be felt.
(this can be experienced to when you feel the bass of a song)
- Frequency range of dog hearing = approximately 40 Hz to 60,000 Hz.
(of course depending on the breed of dog as well as its age)
- Like humans, dogs can begin to go deaf as they become older.
- When dogs become aware of a sound they've heard their ears will prick up and move around.
- Part of the reason why dogs can hear better than humans is that their ears have more mobility which enable it to maximize its ability to ear.
- The shape of a dog's ear also helps it hear more proficiently.
- As we cup our ears, some dogs ears are already in that position.
I have a pet dog, named Putter, who is an adorable Yorkshire Terrior. He is in love with my mother and follows her everywhere, watching her every move. He will listen to my mother's voice whenever she may call him to her bedroom or wherever she might be, and he will immediately flee the area to crawl next to her. On the other hand, I have a father, two sisters, and a brother, and Putter rarely listens to any of us. Of course this isn't a display of Putter's hearing, it is more so that my dog has chosen a favorite, which isn't fair! He is completely obsessed with my mom and it's too the point where if my parents leave for vacation, Putter will lay by the back door, mope around the house, sit with his head down, looking adorable as ever, but feeling so sad. He has such a strong emotional attachment to my mother, and I, to say the least, am jealous. You're probably wondering where I am going with this story, but, trust me, I have a point!
This is where the hearing part comes into play...
Let's say my parents had gone to dinner with a few other couples. Putter would be fine in that case because he somehow knows they will be coming back later that night (he doesn't see any luggage, so that is how he knows). In this case, he doesn't lay by the back door or sulk around the house. Instead, he wanders happily, and if I'm lucky he'll come watch TV with me.
A few hours pass, and Putter has fallen asleep. All of the sudden, he jolts up and races downstairs to the back door. At this point I am confused, wondering if there is an intruder in our home. Putter, being 7 pounds, couldn't really hold off an intruder, so I then got up and went downstairs after him. Lo and behold, my parents walk in. Putter had heard the garage door opening as my parents pulled into the driveway. I didn't hear a thing. It's crazy how good of hearing dogs have.
