Dogs and Noise.

This is very interesting!

Belinda, who lives along Hugo Rd., as we do, sent me late last week a very interesting article on how well dogs can tune out noise.

See you yourself.


How well do dogs hear their name in the midst of chaos?

Humans have the ability of selective hearing, enabling us to tune in to one person speaking, for instance, even in the middle of a noisy room. This phenomenon, dubbed the cocktail party effect, is not unique to humans, however.

Research published in the journal Animal Cognition revealed that not only can dogs recognize their names in noisy conditions, they may do so better than human infants in a similar situation.1 It’s a finding that could be particularly useful for handlers of working or service dogs, who may find themselves needing to attract their dog’s attention in a chaotic environment.

It’s been suggested that hand signals may be best for this, but a vocal command may be preferable, especially since dog’s may miss hand signals as they pay attention to what’s going on in their environment.2

Dogs pick up their names even in noisy environments

For the study, researchers from the University of Maryland used a variety of dog breeds, including pets, service dogs and search-and-rescue dogs, and their owners. The dogs were placed in a booth with their owner, where background noise was played at increasingly loud levels.

Amidst the background noise, a loudspeaker played recordings of a woman speaking the dog’s name or another dog’s similar-sounding name. The dogs listened more intently to the speaker playing their own name and were able to recognize it at varying levels of background noise, up until the noise became louder than the recording of their names.3

“This surpasses the performance of 1-year-old infants,” the researchers noted. Comparatively, adult humans can pick their names out even when background noise is louder than their name. Perhaps not surprisingly, in the study the working dogs performed better at the name recognition than pet dogs.

“I suspect one of the reasons working dogs do better is because people use their names more consistently,” study co-author Rochelle Newman, Ph.D., told National Geographic. “We often end up using nicknames so much.”4 In addition, the researchers concluded:5

“Overall, we find better performance at name recognition in dogs that were trained to do tasks for humans, like service dogs, search-and-rescue dogs, and explosives detection dogs. These dogs were of several different breeds, and their tasks were widely different from one another.

This suggests that their superior performance may be due to generally more training and better attention. In summary, these results demonstrate that dogs can recognize their name even in relatively difficult levels of multitalker babble, and that dogs who work with humans are especially adept at name recognition in comparison with companion dogs.”

Dogs also cue in on other dog and human emotions

Dogs are very in tune with their environments, including the actions and emotions of those around them — both dogs and people. For instance, dogs have been found to display rapid mimicry of the other dogs’ body movements, particularly a play bow and facial expression (a relaxed, open mouth).6

When dogs mimicked each other, their play sessions lasted longer, which suggests it increased the dogs’ motivation to play and possibly strengthened the dogs’ relationship. Given that dogs mimic the emotional states of other dogs, dogs may also be able to mimic their owners’ facial expressions, especially if they’re closely bonded.

“Emotional contagion is a basic form of empathy that makes individuals able to experience others’ emotions. In human and non-human primates, emotional contagion can be linked to facial mimicry, an automatic and fast response (less than 1 second]) in which individuals involuntary mimic others’ expressions,” researchers wrote in Royal Society Open Science. “… All these findings concur in supporting the idea that a possible linkage between rapid mimicry and emotional contagion (a building-block of empathy) exists in dogs.”

The fact that dogs may mimic their owner’s facial expressions and are capable of selective hearing to pick their name out of a host of background noise adds even more understanding of why dogs and humans share such strong bonds.

Dogs associate words with objects

In dog and human communication, it remains a bit of a mystery whether dogs are responding to humans’ words, tone of voice, gestures or other cues — or all of the above.

The featured study suggests dogs do, indeed, respond to their names when spoken verbally, and past research has also shown dogs associate certain words with objects and seem able to form mental pictures that correspond to words they’ve been taught.7 Dogs also tune in to the tone of your voice,8 and may have a heightened response to praise delivered in an upbeat tone. There’s still some debate, though, over whether dogs really understand what you’re saying.

“Some of the old guard say the name is just a bit of noise that is made by the handler, and the dog is familiar with the handler’s voice, so anything the handler says is going to get their attention,” Stanley Coren, Ph.D., professor emeritus of psychology at the University of British Columbia, told National Geographic.9

Yet in the featured study, the dogs responded even though a stranger’s voice said their names, adding more evidence that dogs may understand more than we give them credit for. And, for anyone wondering, there’s evidence that cats also know their names, much like dogs and even when spoken by someone other than their owner.


That dogs, perhaps not all dogs, understand far more than we give them credit is no real surprise. For a creature that bonds so close to humans and has done for a long time we still don’t really know how they function. Well certainly in the head department!

But that doesn’t reduce by one iota our love for them. They are a very special animal.

  1. My Odin does also have a selective hearing. If he thinks, it is a good idea, he will react and come, when called. If not, he will not react at all.
    Interesting article Paul. Dogs are so much more intelligent, that they get credit for. They can learn and understand many words and react to those.
    By my experience, bigger dogs are more easy to raise, as their brain usually are bigger. This is why, I prefer big dogs. The small dogs can be nice, just not for me.


      1. Your dogs are also lucky to live with you, Paul 🙂
        I agree, that good dogs come in all sizes. We are individuals and they are too.
        Here I mostly see, that the small dogs barks a lot and are much more aggressive, than the big ones. This is a challenge for Odin, as he has been attacked by both small and big dogs, while he was walking in the leash.
        Today he is awake for small dogs without a leash. He gets nervous and I have chosen just to release him, if others don’t call their dogs home, when we walk and the small ones come to close to Odin. He is not aggressive, but he is allowed to defend himself, if necessary.
        After have released him some times here now, people have got more respect to let their small dogs without a leash run too close to us.


      2. Oh yes, you are very lucky.
        I moved to a city a while ago, so we need to walk using a leash almost all the time. But Odin learns to be more social with and to other dogs, which is also good.
        I do miss to have my own garden, but needed that move. One day….


  2. And they are all so different. We have a little cattle dog and we have a blue heeler. That heeler is the smartest dog I think we’ve ever had, in that he really attunes and tries to understand every single thing we say. He cocks his head from side to side, like he’s trying to wind in to our language somehow. Where the other dog seems to have selective hearing and waits more on body language. Amazing both, in any case.
