Key Takeaways
A 2012 study in Noise & Health measured four professional forced-air dog dryers at 94.8–108.0 dBA (105.5–108.3 dB SPL) from 1 metre, the typical distance of the groomer and the dog.
Rated ear muffs reduce the noise reaching a dog’s ears while the force dryer runs, which is the loudest part of a groom. Many groomers will fit a dog’s own pair.
Put the muffs on when the high-velocity dryer starts and take them off for the finish. The head and ears are best dried with a gentler stand or handheld dryer, with the force-dryer nozzle kept away from the face.
A grooming snood is light and easy to work around, but it publishes no noise rating. Rated ear muffs such as Dog+ carry an SNR of 27 dB, so they give a known reduction during the drying phase.
Cotton wool is a common salon habit for keeping water out, but it is not a rated hearing protector. It must sit at the entrance of the ear only and always be removed after the groom.
Yes. UK rules require hearing protection once daily exposure reaches 85 dB(A), and roughly an hour beside even the quietest grooming dryer tested is enough to get there.
Dog grooming ear protection comes down to one machine, the high-velocity force dryer that blasts water out of a coat at the table. A 2012 study of four professional dryers measured them at 94.8–108.0 dBA from one metre, which is louder than a hoover and well inside the range where workplace hearing rules start to apply to the people using them.
Groomers know this better than anyone. One grooming trade guide, Groomer to Groomer’s article on high-velocity dryers, puts it plainly: “If we need hearing protection while anywhere near these high velocity dryers, the dogs under the dryers most certainly do.” Dog grooming dryer noise reaches two sets of ears at the same table, and the exposure is very different for each.
At BOLLSEN, a family-owned hearing protection company trusted by 1,000,000+ people, we make Dog+ ear muffs (called ear defenders in the UK) alongside work earplugs for people. This guide to dryer noise is part of our wider dog hearing protection series.
How loud is a dog grooming dryer?
Professional forced-air dog grooming dryers measured 105.5–108.3 dB SPL, or 94.8–108.0 dBA, at 1 metre in a 2012 study published in Noise & Health, a distance the researchers chose as the likely position of both the groomer and the dog. The four dryers were models in common professional use.
The dBA figure is A-weighted, meaning it is adjusted to how human ears hear loudness, while dB SPL is the raw sound pressure. Scheifele and colleagues’ study of grooming forced-air dryers then worked out what those levels mean for a groomer’s working day, using US workplace criteria.
| What the study measured | Value | What it means |
|---|---|---|
| Sound pressure at 1 m | 105.5–108.3 dB SPL | Raw output of four commonly used professional dryers |
| A-weighted level at 1 m | 94.8–108.0 dBA | How loud the dryers are to human hearing |
| Quietest dryer vs the US 90 dBA limit | Over the limit beyond 4 hours a day | The legal US workplace criterion |
| Quietest dryer vs an 85 dBA criterion with a 3 dB exchange rate | Less than 1 hour in an 8-hour day | The stricter, more protective criterion |
Two features of a real salon push those numbers the wrong way. Noise “bounces off metal tubs and cages and can increase the dBA levels in the salon considerably”, according to Groomer to Groomer’s dryer basics for the grooming salon, and a dog’s ear is often nearer the nozzle than the 1 metre measuring point, so the study figures are best read as a floor rather than a ceiling.
On the dog’s side of the question, Matija Medved, DVM, of the Dr.Vet clinic puts the point where dogs can take discomfort or hearing damage at about 85–90 dB. Our decibel guide to how loud is too loud for dogs sets that line against hoovers, thunder and fireworks, and every dryer in the 2012 study measured above it.
What does dryer noise mean for the dog compared with the groomer?
A dog meets the force dryer for one drying phase per groom, typically somewhere around 20 to 40 minutes for a thick or double coat and less for a short one, while the groomer stands beside the same dryers for hours every working day. The level at the table is the same for both, and the exposure time is what separates them.
For the groomer, the concern is the daily dose. For a dog visiting every four to eight weeks, it is a short, very loud session close to the nozzle, repeated across years of grooms, with ears more sensitive than ours.
A force dryer is a broadband roar weighted towards the mid and high frequencies, and that suits ear muffs well. Dog+ attenuation is weakest in the low bass and strongest in the mid and high range, rated M 26 dB and H 29 dB, so a grooming dryer is close to the best case for a passive muff.
Our explainer on how much noise dog ear muffs reduce gives the full frequency breakdown. As a rough estimate, well-fitted cups bring a 95–108 dBA dryer down to somewhere between the high 60s and low 80s at the ear.
When should ear protection go on during a groom?
Ear muffs belong on during the force-drying phase only, going on when the high-velocity dryer starts and coming off when the groomer moves on to clipping, scissoring and finishing around the head. That keeps wear time short in a warm salon.
The head and ears need a gentler tool anyway. Groomer to Groomer’s high-velocity dryer guide advises that “to dry a dog’s head and ears, turn off the velocity dryers and use a traditional stand dryer or gentle tabletop or handheld dryer”, and groomers are warned against running force-dryer nozzles around the face because of the risk to the eyes. Muffs deal with the noise, and keeping the nozzle off the face deals with the air.
Many groomers are happy to fit a dog’s own muffs if you hand them over with the lead at drop-off. The Dog+ earmuffs (SNR 27 dB, sizes XS to L, £69.95) fit most breeds across four sizes with an adjustable headband, and a pair your dog already knows goes on far faster at the table.
How do you get a dog ready to wear muffs at the groomer’s?
Practise at home in short, reward-based sessions for a week or two before the appointment. Our step-by-step guide on how to get a dog to wear ear muffs covers the build-up, and our answer to are dog ear muffs safe explains wear time and checking the ears for warmth afterwards.
Is a snood or ear muffs better at the grooming table?
A grooming snood is a light fabric tube that covers the ears and stays out of the way of the clipper and brush, but it publishes no noise rating, while rated ear muffs such as Dog+ carry a tested SNR of 27 dB. During the drying phase, when the noise peaks, the rated option gives a known reduction, and for close work on the head a snood gets in the way less.
The wider choice, including pressure wraps, is set out in our guide to ear muffs vs snood vs pressure wrap for dogs. At the grooming table itself, the simple rule is muffs while the force dryer runs and a snood or nothing for the finish.
Should groomers put cotton wool in a dog’s ears?
Cotton wool is a long-standing salon habit, and the dryer basics guide tells groomers to “put cotton balls in the ears of the pets being dried”. It helps keep water out and may soften the noise slightly, but it is not a rated protector, it should sit only at the entrance of the ear and it must always be removed after the groom. Our answer to can dogs wear earplugs explains why a dog’s L-shaped ear canal makes over-ear muffs the safer choice.
Is a hair dryer at home as loud as a grooming dryer?
A household hair dryer runs at around 90 dB, similar to a hoover, while a professional force dryer measured 94.8–108.0 dBA at 1 metre, so drying a dog at home is a much smaller noise event than a salon session. A towel does most of the work at home, and the dryer only finishes the job.
Hair dryers, hoovers and other mid and high frequency sounds around the house are covered in our guide to dog ear protection for vacuum and household noise. At home, a low setting held well back from the face keeps both noise and hot air off your dog’s ears.
Do dog groomers need hearing protection themselves?
Yes. Under the Control of Noise at Work Regulations 2005, UK employers must provide hearing protection once daily exposure reaches the upper exposure action value of 85 dB(A), and roughly an hour beside even the quietest dryer in the 2012 study gets there. The HSE’s summary of the noise at work regulations also sets a lower action value of 80 dB(A) and an exposure limit of 87 dB(A), measured with any hearing protection taken into account.
Groomers already know where their own risk sits. The dryer basics guide states that “dryers are the number one cause of hearing loss for the grooming professional”. Hearing protection helps prevent noise-induced hearing damage, but it cannot undo damage already done, so the habit pays off most when it starts early in a career.
The right protector takes off enough noise without cutting the groomer off from the dog. The HSE guidance on choosing hearing protection warns against protectors that cut out too much sound and leave the wearer isolated, and a groomer still needs to hear a dog shift or whine on the table.
Our programme for hearing protection at work supplies reusable work earplugs such as WorkPRO, rated SNR 24 dB, to teams in noisy workplaces, grooming salons included. Worn whenever a force dryer runs, they keep the groomer’s daily dose down.
What does a quieter grooming day look like?
For the dog, it means its own muffs going on with the force dryer and coming off for the finish, with the head and ears dried on a gentler stand or handheld dryer. For the groomer, it means earplugs in whenever a 95–108 dBA dryer is running, whatever the coat.
Hand the muffs over at drop-off and mention the drying-phase routine. Noise exposure adds up over years of grooms and working days, and a few minutes of planning keeps both sets of ears in better shape for longer.
