Different Types of Hearing Aid Domes

hearing aid domes

If you wear hearing aids, you probably have a lot of questions. One of the most common has to do with hearing aid domes. In this guide, we will help you better understand your hearing aids and how to best care for them.

How Often Should You Change Hearing Aid Domes?

How often you replace your domes can depend on many factors. If you don’t wear your hearing aids very much, you may not need to replace them as often as someone who wears theirs every day. On average, however, it’s a good idea to change your hearing aid domes once a month.

Hearing care professionals may recommend that you change your dome sooner or later than once a month, so be sure to speak with your hearing loss professional or one of our trusted audiologists for the most accurate time frame based on your needs.

Where Can I Buy Hearing Aid Domes?

You can find new domes for your hearing aids right on our website. We encourage you to explore the many different styles that we offer so you can be sure to invest in the right domes for your ears. We want you to enjoy a comfortable fit when wearing your hearing aids.

When you visit the link provided above, you will find a variety of domes to choose from, along with detailed descriptions of each dome.

Open Domes

If you suffer from mild to moderate hearing loss, you might need to get our popular open domes. They are one of our most popular, and for good reason. Open domes deliver a more natural sound to the user, as they are equipped with large vents for maximum breathability.

Closed Domes

You might hear some whistling sound with this type of dome, so if that bothers you, you might want to consider closed domes. This small closed dome serves to eliminate whistling almost completely. However, this hearing aid dome is more suitable for those with moderate to severe hearing loss.

Magic Domes

If a comfortable fit is what you’re after, we recommend the magic ear dome. This hearing aid dome is designed to provide stellar comfort and support. If your hearing aids support background noise cancellation, you’re going to love magic domes.

These serve to enhance your hearing aid features so that you get the best sound feedback. They are small, effective, and comfortable.

What Is the Difference Between Open and Closed Hearing Aid Domes?

Open Differences

Open hearing aid domes have vents. These domes are designed to allow more sound to pass through the dome and into your ear canal. When this happens, there isn’t any additional sound amplification taking place. An open hearing aid dome is best suited for people with hearing loss that isn’t too severe.

The downside to using an open dome is that if you turn your hearing aid’s volume up to higher levels, you will likely experience whistling through the dome. To remedy this, simply adjust your hearing aid volume.

Closed Differences

Closed domes, on the other hand, are ones that don’t have any vents. This feature ensures that non-amplified sounds don’t enter into your ear canal. As such, you can look forward to having the ability to crank your hearing aid volume as loud as you like without whistling occurring.

Any whistling is virtually eliminated altogether thanks to this dome. It’s important to note, however, that you may experience occlusion when using this type of dome. Occlusion is when you hear the sounds of your own voice in greater detail.

If this continues to be an issue for you, consider speaking with hearing care professionals. Alternatively, it might be time to search for a new hearing aid. Compare our options to see which one is the best fit for you.

We offer a variety of new hearing aids that can provide the upgrade you need for better hearing. You might simply need a new device to help combat your occlusion and whistling concerns.

What Is the Purpose of a Dome on a Hearing Aid?

There are actually a few reasons to use a dome. Perhaps most important to hearing aid wearers is that they help provide a comfortable fit. If you struggle to keep your hearing aid in your ear, you might find that you just don’t have the right dome size in your ear.

Secondly, an ear dome helps to improve the performance of your hearing aids. An ear dome will connect to a small tube. This tube will then connect to your hearing aid, thus allowing sounds to travel through the tube and into your ear.

If you need help finding the right dome for your hearing aid, we invite you to contact us at Otofonix. We are here to assist you in any way that we can and will be happy to help you find the right size and fit for your needs.

A telecoil acts as a receiving antenna for your hearing aids. When you connect with a sound system of a theater or church, you get amplified sounds delivered directly into your hearing aids. So no matter where you are in the theater, you automatically have the best seat in the house. Only the sound from the hearing loop's microphone is amplified, while background noise is shut out.
