I can remember my first several seasons in the deer woods as a kid. Lets just say I wasn’t the stealthiest. I can hear by dad’s words like it was yesterday, “Pick up your feet”, “Don’t step on sticks”. To be honest, as a seven year old kid I really wasn’t worried about not making noise or a deer hearing me. This begs the question, just how well can deer hear?
Deer senses, like vision and smell, often get the most attention from deer hunters but what about their hearing ability? While whitetail deer don’t have a supernatural hearing ability, with their hearing only being slightly better than our own, its not something that should be overlooked by hunters.
This article will shed light on just how well whitetails hear, covering their basic ear anatomy, hearing range, and compare a deer’s hearing ability to human hearing. After covering the basics of a whitetails hearing, we’ll provide tips on how to use this knowledge to your advantage while your in the woods.
How Deer Ears Work: Anatomy And Mobility
Spend enough time in the woods chasing whitetails and odds are you’ve noticed just how large and how active a deer’s ears are.
The large, cupped outer portion of a whitetails ears are called the pinnae or auricle and is roughly ten times larger than our own. Having large ears allows whitetail deer to detect more sound waves, from multiple frequency ranges.
A deer’s ears are not only large but have the ability to move. Deer are able to rotate each ear independently up to 180°. Instead of having to turn their head, they can just swivel an ear toward a noise. This allows them to easily triangulate sounds at greater distances as well as pick up on frequencies that we cannot.
Frequency Range Deer Can Hear
Several studies have been conducted to determine the hearing range or what frequencies deer can hear.
2007 University of Georgia Study on Deer Hearing
In 2007, researchers at the University of Georgia conducted a study to determine the range of frequencies deer can hear and their hearing sensitivity at each frequency using auditory brainstem response (ABR) testing. The auditory brainstem response testing involved placing three small subdermal electrodes on the deer’s head to measure the brain’s electrical activity in response to different sounds.
The study showed that whitetails can hear a wide range of frequencies, ranging from 0.25kHz to 30kHz, and confirming that deer hearing extends into the ultrasonic range(above 20kHz). The deer in the study showed the greatest hearing sensitivity with moderate frequencies, ranging from from 4kHz to 8kHz with low sound thresholds. Deer having the greatest sensitivity to sounds ranging from 4kHz to 8kHz was to be expected due to the majority of deer vocalizations falling within this range.
At the extreme ends of the spectrum deer hearing was less sensitive. When testing low frequency sounds, ranging from 0.25kHz to 0.5kHz, the average thresholds were 63-64dB, meaning deer required a moderately loud sound to detect very low tones. When testing high frequency sounds, the threshold significantly increased to 70dB(comparable to to loudness of a vacuum) for frequencies at 30kHz.
While this study made headway in determining the frequencies whitetails hear, it was later expanded upon during the 2010 Heffner and Heffner study.
2010 Heffner and Heffner Study
The Heffner and Heffner research conducted in 2010 expanded our understanding of the frequencies deer can hear. The study consisted of two female whitetails that had been domestically raised. Each of the does were trained to drink from a stainless steel water bowl.
During testing, pure-tone sound bursts were played at random intervals. If the deer heard a tone, it learned to break contact with the water bowl to avoid a mild electric shock that was calibrated so that it did not create fear of the bowl. The deer would resume drinking immediately after the tone had stopped.
Heffner and Heffner’s research found the deer to be most sensitive to frequencies around 8kHz, which lines up to the findings of the 2007 University of Georgia study. On the other hand the study expanded the low and high frequency limits previously discovered. Their testing showed that whitetails hear low frequency sounds down to 0.115Hz and high frequency sounds up to 54kHz, expanding the the known frequencies deer can hear.
The findings of the study were not limited to how deer hear frequencies. They also discovered just how much ear orientation affects whitetail hearing at high frequencies. In other words, a deer is much less likely to hear a high-pitched sound coming from behind if it doesn’t swivel an ear in that direction.
How Deer Interpret Sound
If you asked my wife if I listened to everything she says on a daily basis, odds are she would tell you that I have selective hearing. Deer also have selective hearing to a certain extent. The woods is constantly filled with different noises like the rustling of leaves or the sound of water running in a creek. To filter natural and unnatural noises, whitetails have the ability focus in on unnatural sounds. Researchers have given this ability the nickname, the “cocktail party effect”.
They know what sounds belong and the sounds that do not. Natural sounds like leaves crunching, branches breaking, even the occasional loud boom from far off, usually don’t get much of a reaction. But unnatural sounds stick out like a sore thumb:
- Metal clanging
- Candy wrappers crinkling
- Cell phone rings
- The release of a bowstring
A study from the Caesar Kleberg Wildlife Research Institute found deer were twice as likely to bolt from human speech as from predator noises like wolves or coyotes.
How Far Can Deer Hear?
In ideal conditions, minimal wind and open terrain, a deer can hear footsteps in dry leaves at distances of 200-400 yards or metallic noises at distances up to a half mile. The exact distance a deer can hear can vary dramatically depending on factors like terrain/vegetation, wind, background noise, and even the type of sound.
Human Hearing vs Deer Hearing
As mentioned at the start of the article, whitetails don’t have supernatural hearing and is not dramatically superior to our own. Both deer and humans hear low to moderate frequencies at similar intensities.
The following is a brief breakdown of the key differences between deer and human hearing.
Frequency range
- Humans: ~20 Hz–20 kHz.
- Whitetails: similar low end in everyday terms, but sensitivity falls near ~100 Hz; extend well into ultrasonic. Hear 25–30 kHz easily and up to about 54–64 kHz at high levels.
- Both are poor below ~50–100 Hz unless very loud. Deer catch ultrasonic cues humans miss.
Sensitivity
- Peak sensitivity: deer ~4–8 kHz; humans ~2–5 kHz.
- Thresholds near 0 dB SPL at best frequencies for both.
- Deer are better above 10 kHz.
- Humans are slightly better for very deep bass.
Directional hearing
- Deer: large pinnae rotate ~180° independently, enabling fast, accurate 360° localization and on‑the‑fly noise filtering.
- Humans: fixed pinnae, rely on interaural timing and level; more front–back ambiguity and often need head turns.
Hunting Strategies Based On Deer Hearing
While a whitetails hearing may not be as important as there sense of smell, its still a factor hunters should take into consideration each time they step into the woods. The following is a list of tips and strategies to avoid the big ears of a mature deer.
- Reduce unnatural noise: Avoid metal-on-metal sounds, velcro ripping, phone alarms and candy wrappers.
- Time movements with wind: Move or adjust gear when wind gusts mask your noise.
- Use calls within the 4–8 kHz range: Deer vocalizations (grunts, bleats, rattling antlers) fall within their optimal frequencies.
- Approach quietly: Recognize that deer ears can rotate to detect direction; avoid sudden noises.
- Consider scent & sight: While hearing is important, many hunters rank a deer’s nose as its top defense; integrate scent control and camouflage with noise reduction.
