Hearing Aid Tube Replacement - When & How to Change

The tubing on your BTE hearing aid is a critical component that carries sound from the device behind your ear to the ear mold inside your ear canal. Over time, tubing degrades and needs replacement to maintain optimal sound quality and hearing aid performance.

Many hearing aid users do not realize that tubing is a consumable part that requires regular replacement. Worn tubing is one of the most overlooked causes of reduced hearing aid performance.

Signs Your Tubing Needs Replacement

Yellowing or Discoloration

New tubing is clear and transparent. Over time, exposure to skin oils, sweat, and UV light causes the tubing to turn yellow or brown. Discolored tubing has become stiff and is more likely to crack, which causes sound leakage and feedback.

Hardening and Stiffness

Fresh tubing is soft and flexible. When it becomes hard and rigid, it no longer conforms comfortably to the shape of your ear. Stiff tubing can also pull the ear mold out of position, reducing sound quality and causing discomfort.

Cracking or Splitting

Visible cracks in the tubing allow amplified sound to escape before reaching your ear, resulting in reduced volume and potential whistling or feedback. Even hairline cracks that are difficult to see can significantly affect performance.

Moisture Buildup

Condensation droplets inside the tubing block sound transmission. While occasional moisture can be blown out with a puffer tool, frequent condensation indicates the tubing is deteriorating and trapping moisture more easily.

How to Replace Hearing Aid Tubing

While we recommend having tubing replaced by your audiologist during routine visits, some experienced users prefer to do it at home. Here is the general process:

• Step 1: Gently pull the old tubing off the hearing aid hook. It may require a slight twisting motion.
• Step 2: Disconnect the tubing from the ear mold if they are separate pieces.
• Step 3: Thread the new tubing onto the ear mold first, ensuring a secure connection.
• Step 4: Trim the tubing to the correct length. It should be the same length as the old tubing.
• Step 5: Push the tubing firmly onto the hearing aid hook until it fits snugly.
• Step 6: Test the hearing aid to ensure sound is clear and there are no air leaks.

Types of Hearing Aid Tubing

Standard Tubing

The most common type, standard tubing connects a BTE hearing aid to a custom ear mold. It comes in different internal diameters (typically 1.9mm or 2.0mm) to match different hearing aid hooks and ear mold connectors.

Slim Tubing

Thinner and more discreet than standard tubing, slim tubes are used with open-fit BTE hearing aids. They are less visible but may need more frequent replacement as they are more delicate.

Double-Wall Tubing

Some premium hearing aids use double-wall tubing that is more resistant to moisture and has a longer lifespan. This type is less prone to condensation problems.

Caring for Your Tubing Between Replacements

To extend the life of your hearing aid tubing and maintain optimal performance:

• Daily: Wipe the tubing with a dry, soft cloth after removing your hearing aid.
• Weekly: Use a hearing aid puffer to blow moisture out of the tubing.
• Monthly: Clean the tubing with a thin wire cleaner or threading tool to remove any wax buildup inside.
• Storage: Keep your hearing aid in a dry box or with a dehumidifier capsule overnight, especially during monsoon season.

Regular tubing maintenance and timely replacement ensures your Signia hearing aid delivers consistent, clear sound quality day after day. If you need replacement tubing or are unsure about the process, visit our clinic or reach out for assistance.
