Since the invention of the ear trumpet in the 18th century, hearing aid professionals have been searching for better ways to funnel sound directly into the inner ears of individuals with hearing impairments. Over time, this search has proved successful; hearing aids have become smaller, more practical, and increasingly efficient at delivering amplified sound to the auditory system. Innovative research, science and technology continue to enhance listening experiences of hearing aid users, and today, a micro device known as a hearing aid dome provides compatible users with a better hearing quality than ever before.

What is a dome?

A dome is a tiny bell or mushroom shaped silicon piece that attaches to the end of the hearing aid tubing and fits deep into the ear canal. A dome can come in different shapes and sizes to accommodate individual twists and turns of ear canals.

Will I need a dome?

Users of receiver-in-canal (RIC) or receiver-in-the-ear (RITE) hearing aids often use domes to directly amplify sounds into their ears.

Hearing aids with domes are best for those with mild to moderate hearing loss, especially those with high frequency hearing loss (a common type of age-related hearing loss known as presbycusis). Domes are not recommended for those with profound hearing loss. If you do suffer with severe hearing loss, behind-the-ear (BTE) hearing aids with earmolds tend to be more suitable.

Dome also can be problematic for those with dexterity issues due to their small size. If you suffer with dexterity problems, please consult your local audiologist for a suitable alternative.

When do I need to change my dome?

It is recommended that domes should be changed every one to two months, however this can vary from person-to-person.

Your audiologist will show you how to change your dome, however, if you are still unsure, contact your local audiologist for further advice and seek additional help from a family member or friend because a dome can easily get stuck if it is not fitted on correctly. Domes are susceptible to wax and moisture in the ear, so they do require the upmost care.

You should never use old domes with a new hearing aid. They are not always compatible and can become stuck if they detach from the receiver.

How do I remove my dome?

Removing a dome is simple and can be done by firmly grasping the speaker/ thin tube and pulling off the old dome.

How do I replace my dome?

After you have safely removed your dome from the hearing aid, take the new home in your hand and place it the same spot as your old dome. Push the new dome firmly to ensure that it is securely fastened.
