Custom-made earplugs (otoplastieken) are always made from an ear impression. A good impression is the basis for an earplug that seals well and is comfortable to wear. Many people feel nervous about having an ear impression taken, because they don't know what to expect. In this article, we explain step by step how the process works, what to keep in mind and why a good impression is so important.

At Audibling, a partner hearing care professional takes the impressions of your ears. The ear impressions are included in the price and you pay at the hearing centre.

1. Preparation

Before the impression is made, the specialist checks your ear with an otoscope. This is to see whether the ear canal is free of earwax, infections or other blockages. If the ear is not clean enough, it may need to be cleaned first. The impression is only made when the ear is clean and healthy.

2. Protecting the eardrum

To stop the impression material from touching the eardrum, the specialist places a small foam plug in the ear canal. This small foam block, called an otostop, makes sure the impression material reaches exactly the right depth without causing damage or discomfort.

3. Applying the impression material

Next, the specialist uses a syringe to fill the ear canal with a special silicone material that is suitable for medical use. This material fills both the ear canal and the outer ear. It often feels a little cold and can cause some pressure for a moment, but it does not hurt. After a few minutes, the material sets and you have an exact copy of the shape of your ear.

4. Removing the impression

After about five minutes, the material has set and the impression is carefully removed. The specialist checks the impression straight away to make sure it is complete and accurate. All the details of the ear canal and outer ear must be visible to make a custom earplug that fits well.

5. From impression to custom earplug

The impression is scanned digitally or sent to the manufacturer. Using CAD/CAM technology or skilled handwork, a custom earplug is then made that follows the shape of your ear canal and outer ear. After that, the chosen filter is added and the hearing protection is ready to use.

6. Tips for a successful ear impression

Make sure your ears are clean before the appointment. Mention any medical details (ear infections, grommets, hearing loss). Stay relaxed, because the process is painless and quick. Always have the impression taken by a hearing care professional.
