You equalize hearing by using techniques to open your Eustachian tubes, which allow air to flow into the middle ear, thereby balancing the pressure.
Understanding Ear Equalization
When diving, flying, or even going up a tall building, the pressure around us changes. This pressure change can cause discomfort or even pain in the ears. This happens because the air pressure in your middle ear needs to match the pressure in your environment. The eustachian tubes are normally closed but allow air to flow between your throat and middle ear to equalize this pressure.
The Most Common Technique
The most common way to equalize pressure is by using the Valsalva maneuver. This involves:
- Pinching your nose shut.
- Gently trying to blow air out of your nose.
This gentle pressure forces air through the eustachian tubes into your middle ear, equalizing the pressure. According to diving training, "the key to safe equalizing is to get air to flow from the throat to the ears through the opening of the normally closed eustachian tubes."
Other Equalization Methods
While the Valsalva maneuver is standard, other techniques exist:
- Swallowing: Swallowing often helps to open the eustachian tubes.
- Jaw Movements: Moving your jaw from side to side, or yawning can also help.
- Toynbee Maneuver: Pinching your nose and swallowing simultaneously.
- Frenzel Maneuver: Using your tongue to create pressure. This technique is generally more advanced.
Best Practices for Equalizing
- Start early: Equalize before you feel pressure or discomfort.
- Be gentle: Avoid forceful maneuvers as they can cause injury.
- Practice: If you have issues with equalization, practice the techniques in a controlled environment.
- Don't force it: If you can't equalize, ascend slowly or stop until you can.
Equalization Tips for Divers
- Descend slowly: Giving your ears time to equalize as you go down.
- Use a descent line: This gives you something to hold onto to control your descent speed.
- Clear frequently: Equalize every few feet, not just when you feel pressure.
| Method | Description |
|---|---|
| Valsalva Maneuver | Pinch nose and gently try to blow out of it. |
| Swallowing | The act of swallowing can naturally open the eustachian tubes. |
| Jaw Movements | Moving the jaw from side to side, or opening your mouth wide can help in opening eustachian tubes. |
| Toynbee Maneuver | Pinch your nose and try to swallow at the same time. |
| Frenzel Maneuver | Uses the tongue to create pressure. This is an advanced maneuver. |
By understanding the mechanics of ear equalization, you can take the proper steps to ensure your ears remain comfortable and safe in pressure change situations.
