Clearing the ears is an important skill that all scuba divers need to master in order to prevent ear injuries and discomfort while diving. Some people may have an easier time clearing their ears than others due to a variety of factors, including:
Anatomy: The structure of the ear can vary from person to person, and some people may have larger or more flexible Eustachian tubes, which makes it easier to equalize pressure in the middle ear.
Experience: Experienced divers may have developed better techniques for clearing their ears, and are more comfortable with the sensation of equalizing.
Pre-dive preparation: Proper pre-dive preparation, such as staying well-hydrated, avoiding alcohol and caffeine, and using nasal decongestants can help reduce congestion and make it easier to equalize.
Technique: There are different techniques for clearing the ears, such as the Valsalva maneuver, Frenzel maneuver, and Toynbee maneuver. Some people may find that one technique works better for them than others, or may have developed their own personalized technique.
Valsalva maneuver: The Valsalva maneuver involves pinching the nose and blowing gently, creating pressure in the nose that can help to equalize pressure in the middle ear. To perform the Valsalva maneuver, a diver should pinch their nose with their fingers, close their mouth, and blow gently while keeping the nose pinched.
Frenzel maneuver: The Frenzel maneuver is similar to the Valsalva maneuver, but it involves using the back of the tongue to push air into the Eustachian tubes. To perform the Frenzel maneuver, a diver should pinch their nose with their fingers, close their mouth, and make a "K" sound while pushing the back of their tongue against the roof of their mouth.
Toynbee maneuver: The Toynbee maneuver involves swallowing while pinching the nose, which can help to equalize pressure in the middle ear. To perform the Toynbee maneuver, a diver should pinch their nose with their fingers and swallow while keeping the nose pinched.
It's important to note that even experienced divers can have difficulty clearing their ears at times, particularly if they are experiencing congestion or are diving in cold water. If a diver is unable to clear their ears, they should stop the descent and try again after waiting a few moments or ascending a few feet to a shallower depth. If persistent ear pain or discomfort occurs, the diver should ascend slowly and end the dive. Ending you dive only ruins one day, busting your ear drums can ruin a diving career!
