Which Of The Following Animals Could Detect Sound At A Frequency Of 67,000 Hz?

Sometimes, much to our confusion and horror, dogs will all of a sudden alter their behavior and bawl at admittedly null. Information technology's even spookier when they stare directly into an empty corner with an alarmed posture, and you have to ask yourself: "can dogs encounter ghosts?"

Can Dogs Actually Run across Ghosts?

Nigh half of all Americans (47% co-ordinate to a 2019 IPSOS poll) believe that ghosts exist. But do dogs have the ability to assist us prove this one way or another?

Zac Bagans, host of The Travel Channel's Ghost Adventures, believes his canis familiaris Gracie's heightened canine senses let her to feel paranormal action. He even brings Gracie forth to haunted locations in hopes that she can aid their investigations of supernatural experiences.

"I know that she knows when something is at that place in the room… that isn't mankind and claret and os."
Zac Bagans

During i of the Ghost Adventures' investigations at the celebrated William Westerfeld House, Zac picks up on some bizarre beliefs that he's non used to seeing from Gracie. When Zac enters a specific room that is said to be particularly haunted, Gracie jumps upwardly on him to (he believes) get him to leave. Later on in the video, you run across Gracie staring attentively into an empty corner with her ears piqued, then quickly leave with a crouched, fearful body posture a few seconds subsequently.

And this, of course, isn't the only example of dogs interim strange at supposedly haunted locations. A quick YouTube search will give you enough creepy material to have your hair continuing on terminate all night.

What Does The Enquiry Say?

The question of whether dogs tin sense the supernatural hasn't but boggled the minds of paranormal investigators—ordinary pup parents also have their own eerie experiences with their dogs. It'due south an area of study scientists continue to research.

According to Dr. Stanley Coren, a psychology professor and neuropsychological researcher specializing in canine studies at the University of British Columbia, this "sixth sense" that many dog parents believe their pups accept could simply be a consequence of dogs having keener senses than humans ¹.

Dogs Hear At Higher Frequencies Than Humans

Dogs can hear about 4 times better than humans due to their deeper ear canalsⁱⁱ. This allows audio to funnel more direct to their ear drums. Dogs detect softer sounds at decibels (db) nosotros only can't hear—oftentimes between -v dB and -15 dB. Yous know, like the footsteps of that little daughter ghost creaking down your stairs in the heart of the night.

Dogs' supernatural hearing also includes the ability to hear a wider range of frequencies than the human ear. On average, most dogs tin can hear sound as high as 45–67,000 Hz ³ (Hertz is a unit used to measure the frequency of sound). Humans, on the other hand, are only able to hear up to 20,000 Hz. To put that more than plain, dogs tin can hear higher pitches of sound than us—call up of dog whistles that emit sounds out of human being range.

And so, are they simply hearing critters stirring under the floorboards? Or peradventure only the creaks of a settling house? Or are they actually listening to that colonial woman churning butter in your kitchen, and the echos of that little boy who died of scarlet fever playing with his favorite brawl in the afterlife? Well… we might take to leave that one upwards to you to decide for now.

Dogs See Light Spectrums That Humans Tin't

Although dogs may not exist able to see as many colors equally humans (by the fashion, our pups aren't fully color-blind, they simply run across fewer colors than united states of america), or see equally many fine details, they practise have the power to see ameliorate in depression-low-cal conditions, and detect a light spectrum that humans tin't. More specifically, ultraviolet, or UV low-cal.

Y'all know that canteen of sunscreen you have that tells you how much UV light it blocks from the lord's day to go along your peel from burning? Those UV rays are the type of light the human center isn't capable of seeing without the assistance of technology—or dogs!

Then, even if we might not be able to prove yet that ghosts exercise indeed be, or that our canis familiaris is, in fact, sensing those presences, we can prove that our pups are able to see things that we simply tin can't.

Dogs Have A Stronger Sense Of Smell

In that location's a reason your dog loves to olfactory property annihilation and everything in their path, no matter how stinky. And that's because they're picking up and so much more data in one whiff than we could always imagine.

Dogs' sense of smell is about 10,000-100,000 times more sensitive than humans ⁴, and they have well-nigh 300 1000000 olfactory receptors (neurons in the brain responsible for detecting scent), compared to our measly 6 one thousand thousand.

Canis familiaris Noses Smell Decease, Illness, Emotions, & More

Where you and I would just be detecting "domestic dog poo smell," your pup is really collecting all kinds of data and data from the same scent. In one unmarried butt sniff, your dog picks up details about nutrition, gender, emotional country, disease, then much more than from their dog friends⁵.

Dogs' incredible sense of smell goes beyond learning new information about their own species. Dogs' powerful noses give them the ability to to detect all kinds of things, like drugs, explosives, cancer, blood sugar levels, Covid-nineteen, reproductive cycles, emotional states ⁶… and maybe, merely maybe, ghosts also!

While the exact answer as to whether or not dogs tin sense actual spirits is however up for contend, information technology's widely known that dogs tin can, in a way, smell death. Yous've well-nigh probable heard of cadaver dogs and search-and-rescue dogs who help discover survivors or locate bodies later on natural disasters. In add-on, there are also numerous anecdotes about dogs sensing a family member'south impending decease or refusing to leave the side of their person'due south grave later on they've passed.

People Experience "Supernatural" Smells, Too

Meanwhile, at that place have as well been diverse reports of people being overwhelmed with sudden bursts of scents similar cigar fume, perfume, flowers, or nutrient during a supernatural feel. You tin can watch one such incident on an episode of The SyFy Channel'southward Ghost Hunters. In this episode, investigators Steve Gonsalves and Jason Hawes are repeatedly inundated with strong phantom smells of chocolate during an investigation at a reportedly haunted unproblematic school in New Jersey.

The fact that even humans can occasionally connect scents with supposedly haunted locations suggests in that location could be a larger connection to olfactory property and the afterlife than we realize. And perhaps that our dogs observe those scents much more oft.

Dogs Tin Sense Impending Natural Disasters

Dogs are ofttimes able to sense danger before humans can. For example, earlier the massive tsunami in 2004 that destroyed multiple cities across Asia, many animals, including dogs, exhibited behavioral differences and ran for cover or refused to get outside.

This was far from the first fourth dimension animals seemed to predict natural disasters. The commencement recorded incident goes all the way back to Greece in 373 BC when dogs and other animals scrambled to safety days before an earthquake.

Some experts like Stanley Coren believe this miracle could too exist due to animals' heightened senses⁷. During an unrelated canine research study in 2001, Coren noticed the dogs he was monitoring began to showroom signs of anxiety days earlier an convulsion happened to hit the Pacific Northwest. Later on Coren'south observations and data collection on the incident, he concludes, "I believe… it is dogs' hearing abilities, specifically their sensitivity to higher frequency sounds, that allows them to serve as sensors for approaching seismic events such as earthquakes and avalanches."

The truth is, because dogs can't offer their explanation, there'southward no telling why they bawl at nix or act uncharacteristically broken-hearted out of the blue. Until dogs can tell us about Casper the friendly ghost taking up residence in our home, we won't know whether or not they tin see ghosts. But i affair we know for sure is that dogs can certainly see, hear, odor, and perchance sense things that we merely can't. And we think that makes our dogs supernaturally awesome.
