Ear Moulds and Earplugs

We make custom ear moulds for behind-the-ear hearing aids and protective earplugs for swimming, noise and sleep. The ear impression is taken at our centre in a few minutes.

What is an ear mould and what does it do?

An ear mould is a part made to the shape of your ear that carries sound from a behind-the-ear hearing aid into the ear canal. A well-fitting mould delivers the sound correctly, reduces whistling (feedback) and helps you wear the device comfortably all day.

Types of custom earplugs

  • Swimming plugs: Reduce water entering the ear canal; suitable for people with ear problems and frequent swimmers.
  • Noise protection: Help protect hearing in noisy workplaces and workshops.
  • Sleep plugs: Made from soft material to reduce snoring and background noise.
  • Musician plugs: Filtered models designed to lower the volume without distorting the sound.

How is an ear impression taken?

First the ear canal is checked with an otoscope. A small protective block is placed in the canal, then soft impression material is applied. After a few minutes the set impression is taken out and sent for manufacture. The procedure is painless.

When should a mould be replaced?

Moulds can harden or change colour over time, or stop fitting well because the shape of the ear changes. If whistling increases, the mould comes out of your ear easily or it causes pressure, it may need replacing. In children, moulds need replacing more often as the ear grows.

The mould material can be hard, soft, a combination of soft and hard, or biopor; the choice depends on the type of device, the degree of hearing loss and the user's age. Because the shape of the ear changes over time, moulds are replaced every 6 months to 1 year in both children and adults. Custom earplugs are also made for swimmers, divers, people working in noisy environments and people with tubes in their eardrums.

A well-fitting mould also stops the hearing aid from falling out of the ear. The shape and colour of the mould can be chosen as you wish.

Frequently Asked Questions

How often should an ear mould be replaced?

For adults, it is usually renewed every few years, depending on use and material. Children need more frequent replacement because their ears are growing.

Are custom earplugs suitable for everyone?

Because they are made to the impression of your ear, they suit most people. If you have an ear infection or a history of ear surgery, we recommend consulting your doctor first.

My ear mould is whistling. What should I do?

Whistling is usually caused by the ear mould not sitting properly or by earwax. Drop in at our centre; we check the ear mould and the hearing aid and replace them if needed.
