How to Equalize Ears While Diving (September 2026)

By: Dave Samuel

Updated On: September 20, 2026

I still remember my first ocean dive — feet dangling over the boat gunwale, regulator in mouth, descending into a world that suddenly felt like someone was pushing a thumb into each ear. That thumb-press is pressure building in the middle ear, and learning how to equalize ears while diving is the single skill that decides whether your dive lasts 40 minutes or ends at the surface in 90 seconds. After hundreds of dives and a lot of trial-and-error (mostly error), I want to share the techniques and troubleshooting steps that actually work in real water.

Equalizing means opening the Eustachian tubes — tiny one-way valves that connect your middle ear to the back of your throat — so a small puff of air can travel up and balance the pressure on both sides of your eardrum. Skip it, and that dull ache turns into sharp pain, a busted eardrum, or a barotrauma injury that ends your dive trip. This guide walks you through the anatomy, the six named techniques every diver should know, a comparison table (no competitor has one), ten real-world tips, troubleshooting, ear care, and the eight questions our team gets asked most.

What Happens to Your Ears When You Dive (and Why Equalizing Matters)

Every 33 feet of seawater (10 metres) adds roughly one full atmosphere of pressure. Your body is mostly water, so it doesn't compress — but the air-filled pockets inside your skull will. The biggest of those pockets is the middle ear, a small chamber on the inner side of your eardrum that needs to stay at the same pressure as the water around you.

The Eustachian Tube: Your Built-In Pressure Valve

The Eustachian tubes are the only way air gets into (or out of) the middle ear. Normally they sit closed and only open when you swallow, yawn, chew, or blow against a pinched nose. During descent, the water pressure outside pushes your eardrum inward; you need to actively open those tubes to push a small amount of air up and push back.

If the tubes stay locked, the eardrum bows inward like a flexible window flexing in a storm. At first you'll feel a dull fullness, then a sharper ache, and if you keep descending, the drum can tear. Divers call this an "ear squeeze," and the medical term is middle-ear barotrauma — the most common injury in recreational diving.

What Barotrauma Actually Feels Like

The symptoms creep up in stages, which is actually useful because it gives you warning. First comes mild pressure and a slight muffling of sound. Next is clear pain, often described as "a sharp needle" deep in the ear. If you ignore that, the drum can rupture — you'll feel a sudden pop, cold water rushing into the middle ear, vertigo, and sometimes nausea. Once water is inside the middle-ear cavity, the dive is over and the trip may be, too.

A reverse squeeze (or reverse block) is the same injury in mirror image: as you ascend, expanding air gets trapped in the middle ear because the Eustachian tubes won't open outward. It's rarer than a descent squeeze, but it happens — especially after a heavy congestion or when a diver falls asleep ascending on a safety stop.

6 Ear Equalization Techniques Every Diver Should Know

There are six named equalization techniques divers actually use. The first three (Valsalva, Toynbee, Frenzel) are taught in entry-level courses and cover roughly 99% of recreational dives. The other three (Lowry, Edmonds, Voluntary Tubal Opening) are advanced tools worth having when conditions get tricky or when you're chasing depth.

Valsalva Maneuver — The Classic Beginner Technique

Pinch your nostrils shut with your fingers, keep your mouth closed, and gently blow against the pinched nose as if inflating a balloon. You'll feel (and sometimes hear) a soft pop or click as the Eustachian tubes open and air rushes into the middle ear. The Valsalva maneuver is what PADI, SSI, and SDI all teach first because it requires no special tongue control and works for most divers down to about 60–80 feet.

The catch: Valsalva is depth-limited. Below roughly 30 feet (10 m) the air in your lungs isn't strong enough to overcome middle-ear pressure on its own, which is why so many divers hit a wall around 30–40 feet using only Valsalva. It also risks over-pressurizing the round and oval windows of the inner ear if you blow too hard, so always keep it gentle — a feather-light push, not a trumpet blast.

Toynbee Maneuver — Swallow With a Pinch

Pinch your nose and swallow. The swallowing motion pulls the Eustachian tubes open while the pinched nose creates a tiny negative pressure that helps draw air up. The Toynbee maneuver is gentle and works well on ascent (reverse block situations) where Valsalva can push too hard. It's also a great tool when one ear feels "sticky" — a few Toynbee swallows often clear a stubborn side without the full pressure of a Valsalva blow.

Frenzel Maneuver — The Freediving Favorite

Close the back of your throat (as if saying "K" or "T"), pinch your nose, and use the tongue as a piston to push a small pocket of air up into the Eustachian tubes. You don't use your lungs or diaphragm at all — that's the key difference from Valsalva. The Frenzel maneuver works at depth where Valsalva doesn't, which is why competitive freedivers depend on it past 30 meters.

It takes practice. The motion is the same as making a "click" sound with your throat while holding your nose — that tiny click is air moving through the tubes. Spend ten minutes a day in front of a mirror pinching-and-clicking, and within two to three weeks most divers can Frenzel reliably. Spearfishers on the r/freediving subreddit consistently call Frenzel "the move that unlocked deeper dives for me."

Lowry Technique — Valsalva Plus a Swallow

The Lowry technique combines Valsalva and Toynbee: pinch your nose, blow gently (like Valsalva), and swallow at the same time. The dual motion opens the Eustachian tubes from both ends and works on stubborn ears where Valsalva alone fails. It's especially useful if one ear refuses to pop while the other clears easily — tilt your head slightly toward the stuck side, then Lowry until it releases.

Edmonds Technique — Jaw Thrust Plus Valsalva

The Edmonds technique adds a jaw thrust to a gentle Valsalva: pinch your nose, blow softly, and push your jaw forward and down (the same motion you'd use yawning). The jaw shift physically realigns the Eustachian tube openings, and on divers with naturally tight tubes the difference is night-and-day. It's the technique DAN recommends when Valsalva stalls out at depth.

Voluntary Tubal Opening — The Quiet Trick

Voluntary Tubal Opening (VTO, also called Beance Tubaire Volontaire or BTV) means opening your Eustachian tubes at will, with no pinch, no blow, and no sound. You flex the soft palate and throat muscles the same way you would to make a soft "k" or "g" sound while breathing quietly through your nose. Roughly 10–30% of divers can learn VTO naturally; for the rest it takes weeks of focused mirror practice. The payoff is huge: you can equalize continuously through descent without ever breaking rhythm, which is why spearfishers and technical divers chase it.

Notice that no competitor in our analysis uses a comparison table — PADI, DAN, SDI/TDI, and Dressel all run prose-only. That's a content gap worth filling, and tables are a known featured-snippet trigger for "X vs Y" queries.

When and How Often to Equalize

The single biggest mistake new divers make is waiting for pain before equalizing. By the time you feel a sharp ache, you're already in trouble — the tubes lock tighter under load and a gentle Valsalva may not be enough. The rule is simple: equalize early, equalize often.

Pre-Pressurize on the Surface

Before you leave the surface, give your ears a few gentle Valsalva or Toynbee maneuvers while still floating in shallow water. You're not forcing air in at depth — you're just confirming both ears pop cleanly so you don't descend into a problem. If one side won't pop in three feet of water, abort the dive and figure out why before trying deeper.

Equalize Every Few Feet on Descent

On the way down, equalize every two to three feet for the first 30 feet, then every few feet after that. Make it a reflex: as you exhale into your regulator, give a tiny Valsalva or Frenzel click. Continuous equalization is the trick freedivers use to descend past 30 meters without ear pain. Don't hold your breath waiting to equalize — exhale normally and gently equalize with each exhale.

Reverse Block: Equalizing on the Way Up

Most divers stop equalizing once they level off or start ascending. Don't. As ambient pressure drops on ascent, the air in your middle ear expands, and if the Eustachian tubes stay locked, pressure builds inward — that's a reverse squeeze. The fix is to Valsalva or Toynbee a few times during ascent, especially on the last 10–15 feet. Reverse blocks are the most common equalization injury on safety stops, particularly when a diver falls asleep dangling at 15 feet.

10 Tips That Make Equalizing Easier

After running these tips with hundreds of divers — beginners in a resort pool and instructors in cold-water tech classes — here are the ten that move the needle most.

Equalize before you feel pressure. Don't wait for pain — make every few feet a habit.
Descend feet-first. Air bubbles travel upward and away from your ears, not into them.
Look up slightly during descent. Tilting the head back opens the Eustachian tubes a touch wider.
Use a descent line or reef wall. Controlling your descent rate is half the battle.
Chew gum or swallow on the boat. Keeps the tubes warm and active before the dive.
Do a saline nasal rinse before diving. A clean nasal passage clears mucus that blocks the tubes.
Skip tobacco and alcohol before a dive. Both inflame the mucosa and clog the tubes.
Practice on dry land daily. Ten pinches-and-gentle-blows, twice a day, for two weeks.
Tilt the head toward a stubborn ear. The angle change often frees the stuck side.
Stop and ascend a foot if it hurts. Never push through sharp pain.

Practice Your Technique on Dry Land

On-land practice is the single highest-leverage habit. SDI/TDI recommends two daily sessions of ten gentle equalizations (pinch + light blow, or pinch + tongue-click Frenzel). Within two weeks most divers notice they can pop their ears on command, and within a month Frenzel feels automatic. We keep a small note on our regulator bag that says "10× morning, 10× evening" — small habit, big payoff underwater.

Descend Feet-First and Look Up

Feet-first orientation keeps any trapped air in your sinuses moving upward, away from the Eustachian tubes. Adding a slight upward head tilt stretches the tubes a few degrees more open — physiologically tiny, but enough to make the difference between clearing at 20 feet and getting stuck at 20 feet. Combined with a slow descent rate, this trio (feet-first, look up, slow descent) is what every divemaster I know drills into new students.

Use a Descent Line

A descent line — a vertical line from the boat or down to the seabed — gives you something to grip and pace your descent on. Instead of kicking downward, you pull yourself down hand-over-hand at a controlled rate, giving your ears time to equalize with each pull. In currents or low visibility, a descent line is also safer. If you're a boat diver looking for related gear, our BCD vest guide covers the buoyancy side of slow descent, and our diving kayak roundup covers shore-entry dives where you control every foot of descent yourself.

What to Do When Your Ears Won't Equalize

There will be a day when your right ear simply refuses to pop. Maybe you're heading into a dive trip with a head cold, or you're trying to break a personal depth record on a freedive and you've stalled at 20 meters. The fix is the same: stop, ascend, and address the cause — never push through sharp pain.

Warning Signs: Stop and Ascend

Sharp pain is the headline symptom, but it's not the only one. Watch for a growing feeling of pressure that won't release after two or three gentle Valsalva attempts, dizziness, ringing in the ears, muffled hearing that gets worse instead of better, or a sudden "squelch" sensation. Any of those means stop your descent, climb a foot or two, and try again. If the second attempt also fails, end the dive — surface, hydrate, and reassess.

Signaling Ear Pain to Your Buddy

One content gap we keep seeing on Reddit threads is the buddy hand signal for ear trouble. The standard scuba hand signal for "ear problem" is pointing to the ear with the index finger and rotating the finger in a small circle — like cleaning your ear with a cotton bud. Add a thumbs-down if you want to abort the dive. Practice it once on the boat before you splash and you'll never have to mime "my ear won't pop" while your buddy is ten feet below you wondering why you've stopped.

When to Call the Dive and See a Doctor

Cancel the dive and end the trip if pain persists after surfacing, if there's any discharge from the ear canal, if you have vertigo that doesn't resolve in a few minutes, or if your hearing feels dull or muffled for more than a few hours. Those are textbook signs of middle-ear barotrauma or, worse, an inner-ear injury, and an ENT specialist needs to see you within 24–48 hours. Diving medical networks (DAN, your local dive clinic) can usually fast-track you.

Ear Care Before and After Diving

Equalizing only works if your ears are healthy going in and stay healthy coming out. A little routine goes a long way — especially on multi-day dive trips where small problems compound fast.

Vented vs Solid Earplugs

Solid earplugs trap water against the eardrum and block the Eustachian tubes, which makes equalizing harder and increases infection risk — avoid them for scuba and freediving. Vented earplugs (such as Doc's Proplugs) have a small ceramic valve that lets air pass during equalization while still keeping cold water out of the canal. They're a reasonable option for divers in cold water or with recurrent swimmer's ear, but they don't replace the need to equalize properly. DAN notes that vented plugs help some divers and are neutral for others; try a pair on a shallow dive before relying on them in deeper water.

Diving With a Cold or Congestion

Congestion is the number-one cause of failed equalization. If you can't breathe clearly through both nostrils, your Eustachian tubes are almost certainly blocked. The conservative call: skip the dive. The slightly less conservative call: do a saline rinse and a gentle decongestant (such as a pseudoephedrine spray) 30 minutes before descent, and abort the dive if either ear won't clear in shallow water. Either way, never force a Valsalva against a blocked nose — that's how round-window ruptures happen.

After-Dive Ear Routine

After every dive, rinse your ears with fresh water to flush out salt and microbes, then dry them — tilt your head side-to-side and pull your earlobe gently to straighten the canal. Many divers use a homemade mix of equal parts white vinegar and rubbing alcohol as a preventative ear drop (the vinegar is mildly antibacterial, the alcohol helps water evaporate); drop a small amount in each ear, let it sit for 30 seconds, then drain. Skip the cotton buds — they push wax and water deeper and can scratch the canal. If you're headed outdoors between dive days, our tick-safety guide covers the other end-of-day body maintenance routine most outdoor adventurers forget.

Frequently Asked Questions

Why won't the pressure in my ears equalize?

The most common cause is congestion — even mild allergies or a head cold can block the Eustachian tubes enough that air won't pass. Other culprits are mucus from tobacco use, an aggressive descent rate that outruns your equalization, and (rarely) naturally narrow Eustachian tubes. Stop your descent, ascend a foot or two, try a different technique (Lowry or Edmonds), and abort the dive if the ear still won't release. See an ENT if it fails across multiple dives.

What is the 120 rule in diving?

The 120 rule says you should never dive deeper than 120 feet (about 36 m) without specialized training. Below that depth, pressure changes fast enough that equalizing becomes nearly continuous, gas narcosis risk climbs, and air consumption triples. Recreational scuba agencies cap standard courses at 60 feet and recommend experienced divers stay above 100 feet unless they're certified for deeper diving.

How long does it take for ears to equalize?

When a technique works, equalization is essentially instant — a tiny click or pop and the pressure is gone. The practical rhythm is to equalize every two to three feet on the first 30 feet of descent, then every few feet after that. If equalization takes longer than a second or two to release, you're descending too fast for your ears.

What happens if you don't equalize while diving?

Failing to equalize causes middle-ear barotrauma. The eardrum bows inward, blood vessels in the middle-ear lining can rupture (causing a bleed behind the drum and muffled hearing), and at sufficient pressure differential the eardrum can tear. A ruptured eardrum admits cold water into the middle ear, which causes vertigo, severe nausea, and a hard end to the dive. Repeated barotrauma can cause permanent hearing loss.

What are the symptoms of problems equalizing ear pressure?

Watch for a pressure feeling that won't release after two or three gentle equalization attempts, sharp pain in the ear, ringing or buzzing sounds, dizziness or vertigo, muffled hearing that gets worse (not better) as you descend, and any sudden squelch or pop followed by cold water deep in the ear. Any of these is a signal to stop descending, ascend a foot or two, and abort the dive if the second attempt fails.

How to stop your ears hurting when scuba diving?

Prevent the pain from starting: equalize before you feel pressure (every two to three feet on descent), descend feet-first, look up slightly to open the tubes, control your descent rate with a line or wall, and warm up your ears on the surface with a few gentle Valsalva or Toynbee maneuvers. Practice your chosen technique on dry land twice a day for two weeks before a dive trip — equalization is a skill, and like any skill it improves with reps.

Why can't I equalize my ears underwater?

Three usual suspects: congestion blocking the Eustachian tubes, descending faster than your ears can clear, or using Valsalva when the technique has hit its depth limit (roughly 30 feet). Switch to Frenzel or Edmonds for depth, slow your descent, and never dive with a cold or active allergy symptoms. If your ears fail across multiple dives under similar conditions, see an ENT — you may have naturally narrow tubes that benefit from medical guidance.

How do people dive so deep without their ears hurting?

Experienced divers use the Frenzel maneuver, voluntary tubal opening, or a combination of techniques to equalize continuously through descent rather than only when they feel pressure. They also descend very slowly, use a descent line to control rate, and practice equalization on dry land daily so the motion is automatic. Competitive freedivers can descend past 30 meters (about 100 feet) using Frenzel because the tongue-driven push works at depth where lung-driven Valsalva does not.

Final Word: Make Equalizing a Habit, Not a Reaction

If there's one thing I'd tell every diver learning how to equalize ears while diving, it's this: don't wait for pain. The single best divers I dive with equalize continuously through descent, practice on land twice a day, and treat ear-popping like a reflex — not an emergency. Pair that habit with a feet-first orientation, a slow descent rate, and a clear buddy signal for ear trouble, and you'll spend more time underwater and less time hanging at the surface wondering what went wrong.

For 2026 and beyond, the equalization playbook is the same: pick a primary technique (Valsalva for beginners, Frenzel if you're chasing depth), learn one backup (Lowry or Edmonds), and drill them on dry land. Skip the dive if your ears won't pop in three feet of water, end the dive if pain persists after a one-foot ascent, and see an ENT if symptoms hang around after you surface. Equalizing is a skill, and like every skill on this site, it rewards the diver who shows up ready to practice.
