Custom Earmolds and Earplugs
Protection
What is a custom earmold and why would I need one?
ZN Audiology offers custom-made earplugs for musicians, swimming, sleep and noise protection at both clinics. Each pair is individually molded for a secure, comfortable fit and reliable hearing protection. The practice also supplies custom hearing aid earmolds. A custom mold is made from an impression of your own ear rather than a standard shape, which is what makes it seal reliably, sit comfortably for long periods, and deliver the attenuation or acoustic coupling it was designed for.

About Custom Earmolds and Earplugs
The one part only a clinician can do is the impression. Everything a custom mold does better (sealing without pressure, staying put, attenuating by the amount it claims to) comes from being made to the actual shape of your ear canal, not to an average.
Protection depends on choosing an appropriate device, fitting it correctly and wearing it consistently. A custom shape can help with fit, but it still needs correct insertion and a good seal. Laboratory noise-reduction ratings are not a guarantee of the protection an individual will achieve.
Custom molds are made for hearing aids, for swimming and water protection, for sleep, for industrial noise, and for music. The material and the fit differ by use, which is what we determine at your appointment.
What this includes
- Impressions taken at either clinic
- The impression is the clinical step. Everything else follows from getting it right.
- Hearing aid earmolds
- For behind-the-ear devices, where a leaking mold causes feedback and lost low frequencies.
- Swim and sleep plugs
- Water protection and long-wear comfort are different design problems and call for different materials.
- Noise and music protection
- See the hearing protection page for filtered musicians’ plugs and industrial protection.
Questions about custom earmolds and earplugs
The audiologist examines the ear canal first, places a small foam block to protect the eardrum, then fills the canal with a soft silicone material that sets in a few minutes and is removed as a mold of your ear. It is not painful, though the sensation of the canal filling is unfamiliar the first time.
