Domes Domes Domes!


Hearing aid domes are small, conical or mushroom-shaped pieces of soft, flexible material that fit over the end of the hearing aid's tubing or receiver. They are designed to create a seal in the ear canal to help keep the hearing aid securely in place and to help amplify sounds effectively. Hearing aid domes come in a variety of shapes and sizes to accommodate different ear canal sizes and types of hearing loss.


Hearing aid domes usually have the following features

  1. Material: Hearing aid domes are typically made of soft, flexible materials such as silicone or polyurethane that are comfortable to wear and conform to the shape of the ear canal.

  2. Shape: There are several shapes of hearing aid domes available, including conical, mushroom, and tulip shapes. The shape of the dome is designed to fit comfortably in the ear canal and create a seal to help prevent feedback and improve sound quality.

  3. Size: Hearing aid domes come in different sizes to fit different ear canal sizes. They are typically labeled with a size number or letter that corresponds to the diameter of the dome.

  4. Venting: Some hearing aid domes have small vents or openings that allow air to flow into the ear canal, which can help reduce the sensation of occlusion or a "plugged-up" feeling.

Now that you know about the different domes, what domes is best for me?

Here is a general guideline of what type of hearing aid dome might suit different types of hearing loss:

  1. Mild to moderate high-frequency hearing loss: Open-fit domes or tulip-shaped domes may be a good choice for this type of hearing loss. These domes allow low-frequency sounds to be amplified naturally while also providing some amplification for higher frequency sounds.

  2. Moderate to severe hearing loss: Power domes or double domes may be a good choice for this type of hearing loss. These domes have larger diameters and more volume, which can help provide more amplification for sounds.

  3. Narrow ear canals: Slim-tip or ultra-slim domes may be a good choice for people with narrow ear canals, as they have a smaller diameter and can fit more comfortably in the ear.

  4. Feedback issues: Closed domes or double domes may be a good choice for people who experience feedback or whistling sounds with their hearing aids. These domes create a tighter seal in the ear canal, which can help prevent feedback.

It is important to note that these guidelines are just a general rule of thumb, and the best type of dome for a person's hearing loss will ultimately depend on several factors, including their specific type and degree of hearing loss, the shape and size of their ear canal, and the specific hearing aid model they are using. A hearing care professional can help determine the most appropriate type of dome for an individual's needs.
