The Most Important Thing to Know about Ear Protection for Dogs

Most of you are going to be disappointed if you buy ear protection (muffs, hoods) for your thunder- or firework-phobic dog. I’m going to give you enough information here to decide whether ear protection might help, and you can decide for yourself.

The Problem with Ear Protection for Low-Frequency Noises

The most important thing to know about ear protection for dogs is that it won’t work well against thunder and fireworks. No matter the marketing claims, no matter the good fit. It can’t.

The protection from sound that barriers like ear gear can provide isn’t the same for high-pitched and low-pitched noises. Ear gear can prevent the transmission of sound well at high frequencies (birdsong, digital beeps, whistling, bats, and higher noises we can’t hear) and poorly at low frequencies like thunder and fireworks. Low-frequency sound waves are gigantic pressure waves that are so much larger than the inch of material in ear muffs that they go straight through them with much less decrease in volume than higher frequencies do. That’s physics—you can’t get around it.

Also, sound waves, especially low-frequency ones, travel through our skulls (Stenfelt & Goode, 2005). They don’t have to enter through the ear canal. This almost certainly happens to dogs as well, since their auditory systems have similar physical structures.

When your dog wears ear protection, there will be some decrease in the volume of the low-frequency sounds, but they will still hear those sound just fine. We tend to imagine that sound barriers block sound completely, but they don’t. Ear protection will not create anything resembling silence for your dog. Active noise control systems were invented because passive sound barriers are insufficient for low-frequency noises. Please read the first paragraph in the linked article. It’s by two of the most eminent acousticians in Great Britain, experts on noise control.

In graduate school, I worked with loud, low-frequency sound. I went to a gun store and purchased the best quality ear protection I could find. I doubled up with foam earplugs. I couldn’t hear my teacher well enough to understand his speech when he was standing right in front of me, but I could still hear our 125 Hz sound signal loud and clear. I could feel it in my body. But it was diminished enough by my gear that I didn’t get ear damage.

Speaking of preventing ear damage—this is the original purpose some ear protection for dogs was brought to market. Mutt Muffs, for example, were marketed to people who took their dogs or motorcycles or private planes. In that situation, even a 10-decibel (dB) decrease can make a difference.

What about That “30 dB Decrease in Sound” Some Products Claim?

This talking point is actually a red flag.

Many sound products advertise a “30 dB decrease in sound” for their product. When they compute that decrease, they are computing across the whole sound spectrum, so it’s something like an average. There are complications that mean it’s not exactly an average, but for our purposes we can think of it that way. The important thing is that they are computing over all frequencies. So while you might get 40 dB or more reduction for higher frequencies, you might only be getting12 dB reduction on a 110 dB thunderclap. And even if you got 20 dB on that thunderclap, it would still be awfully loud.

So, this “30 dB” claim does not mean that the sound waves from thunder and fireworks are reduced by that amount. An honest company will tell you that, and provide a spectral analysis—a graph that shows the reduction in each frequency range. A less honest company will stick with the “30 dB decrease,” and hope you assume that applies to the sounds your dog is concerned about. Acoustics is counterintuituve and most of us get no training in it, so we would have no reason to disbelieve them.

“Noise-Canceling”: Another Red Flag

There is a headset with electronics on the market that is advertised to perform active noise cancelation for dogs. I wrote a full review of it. But I’m bringing up the term here because it is sometimes used to advertise non-electronic ear protection like I’m discussing here. The latter is a deceptive use of the term. If headphones don’t have batteries and electronics in them, they are performing passive sound reduction, not active. Another inaccurate term used is “sound-blocking.” I wouldn’t buy a product that uses disingenuous terminology to make sales.

Final Red Flag: “It’s Patented!”

There is at least one ear protection product whose marketing leans heavily on the fact that they have a patent. I’ve looked it up, and it’s true. But the patent is for how the gear fits and fastens around the dog’s head. It doesn’t have anything to do with the product’s ability to prevent sound from entering the ears.

Which Dogs Might Benefit

If your dog is not worried when they hear fireworks or thunder from far away, then ear protection might work for closer noises. The dog will still hear them, but they will be diminished somewhat. Some might be decreased to the level of far-off sounds. For some dogs, this decrease in volume might help.

But many dogs with clinical sound phobia learn that those rumbles in the distance are precursors to the louder ones. That’s how conditioned fear works: a stimulus that predicts something scary can become scary itself. My dog Lewis is afraid of far-off, relatively quiet thunder. So a gadget that made closer thunder sound far off wouldn’t help.

And no gear can help with those thunderclaps that are close or right on top of us. They will still be very loud, even through earmuffs.

How to Choose

None of these products are going to be super effective at preventing the transmission of low-frequency waves. But if I still wanted to try some, I’d look closer at the company’s marketing. I won’t buy from a company that makes fraudulent claims.

Of the ear protection products I know of, Rex Specs has the most honest marketing. They publish a spectral analysis and point out that their Ear Pro is less effective at lower frequencies. I don’t know whether their product is superior to others in performance, but they’ve shown us honestly what it can do. Hush Muffs also gives a good accounting of what the product can do, but, being a cloth-based item, it attenuates sound less. On the other hand, 4Paws Aviation K-9 Ear Muffs publishes misleading information. They claim a 41 dB reduction in sound, but they completely eliminate low frequencies from the computation, which inflates the average. (If they have disclosed that omission and acknowledged the effect of it on their site, please let me know and I will amend my remarks.)

Finally, I would weigh the effort of conditioning the gear against the gamble of a benefit. See below.

Conditioning

I mentioned above that items or events that predict scary things become scary themselves. Unfortunately, this can work perfectly for the event of “bringing out the earmuffs.” If you use them without first conditioning them, they can become a perfect predictor of “SCARY NOISES COMING.” So you need to condition them—separately from loud noises—to predict great things. And even after they are conditioned, you would ideally have your dog wear them (and get good stuff) for time periods without scary sounds.

So if you decide to try this kind of gear, you’ll need to condition the hell out of them with a very careful protocol. If this is above your skill level (it’s above mine for my current dog), get help from a positive-reinforcement based trainer who specializes in husbandry.

That’s a whole lot of prep work for something that might not be effective. But it could be worth it for some dogs, such as those who are bothered only by the loudest thunder or fireworks.

A Better Use for Ear Protection

I’ve been planning to write another piece on this, but what the heck. You know what situation calls for ear protection? Grooming. That’s because the noises of grooming—clipping and drying—have high frequencies and are often very close to the dog’s head. Ear gear could help a lot. I tested a standard handheld hair drier for humans with my ultrasound mic and found that it puts out loud ultrasound as well as the frequencies we can hear. Those gadgets are even louder than we humans can perceive. But dogs with normal hearing will hear all of it—unless they can wear good quality ear protection, which works well against high-frequency sounds.
