How to Equalize Ear Pressure (Tips When Diving)

One of the activities where there’s an abrupt change in the internal pressure in the air is scuba diving and other types of diving.  In this case, the air or fluid builds up in the eustachian tubes, which is a passageway that connects the throat muscles to the middle ears.

The challenge for divers is to be able to go deeper by eliminating the effects of ear pressure changes underwater. The common way to deal with water pressure is through ear pressure equalization.

In this article, know more information about how to equalize your ears through different equalizing methods, and we’ll give you some diving tips.

Equalizing: What is It?

As you go deeper into the waters, the water pressure also increases, creating an imbalance with the pressure that circulates in the ear.

Even though the human ears have the ability to adapt and regain balance naturally, it’s not well adapted with the environment in the waters, especially as you go deeper, so you need to manually maintain balance through equalizing. 

 The pressure that builds up in the ear may result in pain and discomfort and is commonly associated with dizziness and temporary hearing distortion. The only way to avoid air or fluid pressure from building up in the ear is to let the eustachian tubes open through equalization or ear clearing.

Methods Used To Equalize Your Ears

When you’re underwater, the different parts of the ear—eustachian tube, eardrum, and outer ear—are at risk of infection that may cause hearing problems when there’s a problem with equalization. There’s a general rule for divers to always equalize their ears before and while descending in the waters. 

Here are some of the ear equalization methods used by divers to relieve pressure and prevent long-term damage to the ears:

Valsalva Maneuver

This is a basic method for equalization that’s often introduced to beginner divers. You’ll just have to pinch your nose and exhale gently with a force like you’re blowing in a tissue. By doing this, the air trapped along the closed eustachian tubes and along the middle ears is forced to move.

Toynbee Maneuver

The Toynbee Maneuver method is an integration of the Valsalva Maneuver and swallowing. You have to pinch your nose while swallowing and make sure that your tongue is positioned on the roof of your mouth. This method doesn’t squeeze the eustachian tubes, but it enables the throat muscles and soft muscles movement to equalize the pressure.

Frenzel Equalization

With this method, over-pressuring the inner and middle ear is prevented. You’ll just have to pinch your nose gently. If you’re to do this before descending on the waters, make sure that your nose is just half pinched or half-closed. 

With your mouth closed, situate your tongue behind the tip of your upper front teeth like when you say the sound of the letter “t” or place your tongue in the middle of the mouth’s roof like when you would say “k.” Your soft palate muscles must be relaxed to allow the air to travel into the nasal cavity. 

Voluntary Tubal Opening

The idea of the voluntary tubal opening is to tense the soft palate while pushing the jaw forward. A perfect example of this is by yawning or just imitate the position of your jaw when yawning.

Through this, the muscles on the mouth and throat open your eustachian tubes. Another example of the jaw forward tense is when you chomp on chewing gum.

Valsalva vs Frenzel Equalization – Which Is Better? 

It’s quite hard to distinguish the difference between Valsalva and Frenzel equalization just by observing it because the gestures are just the same, but it would differ based on how the air is pushed into the eustachian tube.

In Valsalva, the air is pushed through the lungs via the windpipe or the larynx in the lungs into the eustachian tube. Through this technique, there’s pressure created into the lungs and diaphragm. For Frenzel, there’s no pressure created into the lungs because it’s the glottis responsible for releasing the air in the mouth and throat. 

If you’re doing Valsalva, it’s hard to get enough pressure from your lungs due to compression. So, if you want to descend further, you need to shift to Frenzel Equalization

Tips For Improving Your Dive Efficiency 

For a safe and enjoyable diving experience, here are some of the tips that every diver must consider.

Learn To Clear Your Ears

Avoid pain and possible damage to the ear by practicing correct ways to equalize or clear the ear. Equalization is the way you can move deeper safely. 

Maintain Buoyancy Control (Scuba)

To be able to descend at your desired depth,  you must be able to control your buoyancy by observing proper breathing and having the proper weight.

Maintaining the right buoyancy would not let you float or sink too quickly. If you’re about to touch a coral reef, you’ll just have to take a deep breath, and it’ll improve your buoyancy.

Never Dive Alone

This is most especially for beginner divers.  The diving buddy system ensures that divers are still safe even though equipment fails to function properly or if there’s an emergency.

For example, if your breathing apparatus stops working, your buddy may quickly attend to give you a backup breathing device. 

If you don’t have a buddy, there’s a tendency that you’ll run out of air before even reaching the surface of the water, or you’ll rush to ascend, leading to decompression sickness which is dangerous. 

Ascend Slowly (Scuba)

To avoid decompression sickness, ascend slowly. Ascending too quickly may forced nitrogen into your bloodstream that may cause confusion, poor judgment, or worst paralyze. Instead, give your body time to dissipate nitrogen in your body by coming up slowly.

One of the most common injuries that a diver may experience is an ear problem or ear barotrauma. That’s why learning how to equalize ear pressure is a must-have skill that a swimmer or diver should learn. Different methods are used to equalize ear pressure; you’ll just have to practice to ensure that you’re doing it correctly. 

Aside from knowing the proper methods of equalizing your ears, you must also practice responsible diving to protect the marine environment and to keep you safe at all times.
