How is Your Dog’s Hearing?
Here’s another Tale of Tails, Tino edition. A few weeks ago we talked about his sense of hearing and smell when he tracked us down in Big Bear. Today I have another story about his sense of hearing and I bet many of you can relate to this skill.
We live in a gated community (believe me, it’s not as fancy as it sounds). Our house sits almost parallel to the entrance street, with one house in between, if all the bushes were gone, you could see the community gate from our backyard.
As I’ve said before Tino would spend most of his day in the backyard, usually sleeping in some odd location.
Whenever I came home Tino would greet me at our family room door. That’s not the special part – you have to understand what that means. Here’s the steps he would have to go through to get from his napping spot in the backyard to that door:
- Wake up.
- Recognize it was MY car vs. the many other cars that might be going through the gate.
- Make his way (at high speed) from wherever he was in the yard to the back door and the dog door.
- Push through the dog door and then make a left turn down the hallway.
- Make another left turn down another hallway.
- Navigate two steps up to the dining room.
- Make a right turn and get thru the dining room into the kitchen (without running into the table).
- Make another right turn to the family room landing.
- Go down two steps into the family room.
- Cross the family room to the door.
- Stand there waiting – all before I pulled into the driveway.
- Oh, and be blind while doing all of this.
And he was there – every. single. time. Did I say he was amazing?
Dogs hearing is far superior to humans. Although they are born deaf, when fully developed, their sense of hearing is at least 4 times better than humans. They are more sensitive to high pitched noises. They detect noises in the range of 40,000 – 60,000 Hz, while humans is only 20,000 – 23,000 Hz. What’s a Hz?
Wikipedia states: The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI). It is defined as one cycle per second. A better description from InformedHealthOnline is: The frequency is how many vibrations there are per second. For instance, 20 hertz means 20 vibrations per second. This very slow vibration can barely be heard and as a very low tone. The higher the frequency, the higher the pitch.
Dogs also have more muscles in their ears than humans and may be able to turn their ears in the direction of a sound to improve their ability to hear it. Dogs with perked ears tend to have slightly better hearing than dogs with hanging ears.
The simple answer is YES, dogs can hear better than humans and Tino was sure proof of that.
