Ear Impressions and Custom Moulds

Because protected ears hear longer.

A custom ear impression is the critical first step in obtaining any high-quality, custom-fit ear device, be it a custom ear mould or a hearing aid mould. Based on the rigorous standards set by the British Society of Audiology (BSA), as well as guidelines from the National Institute of Health and Care Excellence (NICE), this safe and simple procedure provides an exact, three-dimensional blueprint of your unique ear canal and outer ear anatomy. It is more than just a mould, it is the guarantee that your final product will perform exactly as intended.

Why Custom Impressions are Critically Important

The human ear is as unique as a fingerprint; there is no such thing as a "standard" ear. The small differences in the shape and angle of your ear canal can have a massive impact on the effectiveness of your custom mould. The impression is essential for unmatched comfort, as the mould precisely matches your ear's contours, eliminating pressure points and chafing, making all-day wear effortless, whether you are wearing hearing protection for work or a custom mould for a personal hearing instrument. It is also vital for optimal acoustic sealing. A perfect impression ensures a tight, secure acoustic seal. This seal is crucial for maximum noise attenuation for ear protection and for ensuring the sound from an attached hearing instrument is delivered effectively without acoustic escape. Finally, it guarantees secure retention, meaning your custom-fit device stays reliably in place throughout your day, even during movement or jaw articulation.

Custom vs. Generic: The Superior Performance Advantage 

The devices made from your custom impression offer undeniable advantages over one-size-fits-all or generic solutions. A custom-made device provides a perfectly matched fit, whereas generic items rely on standard shapes or compressible foams that often lead to irritation and discomfort over time. Crucially, a custom mould results in an airtight acoustic seal that prevents noise ingress for earplugs and prevents sound leakage for hearing aid moulds. In contrast, generic devices often have an inconsistent and unreliable seal, drastically reducing their effectiveness and comfort. While generic products often loosen or fall out with jaw movement, your custom device securely locks into your ear's unique anatomy, providing reliable, consistent protection or coupling.

The Safe and Simple Procedure 

The process is quick, clean, and guided by BSA protocols, with your safety as the highest priority. The procedure starts with your informed consent and a detailed otoscopy (ear canal check) to ensure your ear is healthy and clear of any contraindications. Safety is paramount: a small protective barrier, called an otostop, is gently placed deep in the canal to safeguard the eardrum. The high-grade silicone impression material is then carefully inserted to fill the canal and outer ear bowl. You will feel a temporary sensation of fullness or pressure and possible the sensation to cough. You must not speak during the brief setting time (roughly 3-5 minutes), though you can signal any discomfort with a simple hand raise. Once fully set, the impression is gently removed, and your ear is immediately re-examined. The result is a perfect, custom mould that guarantees you receive the best possible device—a truly bespoke solution for your ear needs.
