Equalizing Methods Compared: Valsalva, Frenzel, Toynbee

Introduction

If your ears hurt on descent, equalization technique is usually the difference between a smooth dive and a canceled one. As you descend, pressure increases and your middle ear space has to be re-pressurized through the Eustachian tubes. If that pressure isn’t matched quickly, the eardrum gets pulled inward and pain starts.

Most divers are first taught Valsalva (pinch + blow), but that’s only one method. This guide breaks down what Valsalva, Frenzel, and Toynbee are, exactly how to do each one, and when each is most useful underwater.

How Equalization Works (Quick Version)

Your middle ears are air-filled spaces behind the eardrums. On descent, outside pressure increases immediately, but middle-ear pressure doesn’t unless air moves up the Eustachian tubes. Equalization is just opening those tubes and letting pressure equalize before discomfort builds.

Golden rule: equalize early and often — ideally before you feel pain.

1) Valsalva Maneuver — What It Is and How To Do It

What it is: The most common beginner method. You pinch your nose and gently blow against closed nostrils to push air toward the middle ears.

1. Pinch nostrils closed with mask hand.
2. Keep mouth closed around regulator.
3. Blow very gently for 1–2 seconds (not forceful).
4. Listen/feel for a soft “pop” or pressure relief in both ears.

Pros: Easy to understand and quick to learn.

Cons: Easy to overdo. Blowing too hard can irritate ears and worsen blockage.

Best for: New divers and mild pressure changes in shallow portions of descent.

2) Frenzel Maneuver — What It Is and How To Do It

What it is: A more refined method used heavily by freedivers and advanced scuba divers. Instead of chest pressure, you use your tongue/throat to compress air in the upper airway.

1. Pinch nose closed.
2. Close the back of your throat (as if holding breath without chest strain).
3. Use the back of your tongue like a piston (as if pronouncing a soft “K” or “G”).
4. Create a short, controlled pressure pulse upward into the Eustachian tubes.

Pros: More precise, gentler, and works better during continuous descent.

Cons: Takes practice on land before it feels natural.

Best for: Divers who struggle with Valsalva, deeper descents, and frequent equalization cycles.

3) Toynbee Maneuver — What It Is and How To Do It

What it is: Pinch the nose and swallow. Swallowing activates muscles that help open the Eustachian tubes while the pinched nose creates a pressure shift.

1. Pinch nose closed.
2. Do a deliberate swallow.
3. Repeat as needed every few feet during descent.

Pros: Very gentle, useful if Valsalva feels too aggressive.

Cons: Can be slower and less effective if tubes are already tight/congested.

Best for: Slow controlled descents and divers who respond well to swallow-based clearing.

Quick note on spelling: It’s Toynbee (sometimes mistyped as “Tonybee”), named after physician Joseph Toynbee.

Which Method Should You Use?

• Starting out: Begin with light Valsalva and frequent pauses.
• If Valsalva feels forceful: Practice Frenzel on land, then use it in-water.
• If ears are sensitive: Try Toynbee between Valsalva/Frenzel attempts.
• Most effective real-world approach: A hybrid — tiny, frequent equalizations every 1–3 feet of descent.

Troubleshooting by Symptom

• One ear clears, one ear lags: Slow down, tilt the blocked ear slightly up, and do a gentle Toynbee swallow before another Frenzel attempt.
• No pop, just pressure build-up: You may be too late. Ascend a few feet and restart equalization before descending again.
• Sharp stab of pain: Stop immediately and ascend. Do not force a second hard attempt.
• Clicking but no relief: Tube may be opening briefly but not long enough—switch from large pushes to smaller, repeated pulses.
• Works at first, then suddenly stops: Fatigue/tension is common. Pause, relax jaw and neck, and reset your descent pace.

When Equalization Fails

If one ear won’t clear:

• Stop descending immediately.
• Ascend a few feet.
• Try again gently (never force).
• Tilt blocked ear upward and try swallowing/jaw movement.
• If pain continues, abort the dive.

Never push through pain. Ear barotrauma can happen fast and can ruin diving for weeks.

Pre-Dive Prep That Actually Helps

• Hydrate and avoid heavy mucus triggers before diving.
• Do light jaw mobility (open/close, side-to-side) before gearing up.
• Equalize once at surface before initial descent.
• Descend feet-first on a line when possible for better control.
• Avoid diving with active cold/sinus congestion.
