Reducing Hearing Aid Repairs
Recent advances in hearing aid manufacturing technology has produced nanotechnology protective coatings for delicate electronics and parts that are significantly reducing hearing aid repairs.
ReSound, one of the industry’s top 6 manufacturers, recently announced that its iSolate Nantotech protective coating has reduced moisture related repairs to its hearing aids by 50 percent since its introduction six months ago.
How Do the Coatings Work?
How are protective coatings reducing hearing aid repairs? ReSound’s iSolate nanotech coating, now used in all of ReSound’s hearing aids, establishes a thin protective layer that bonds at the molecular level with the internal and external components of the
hearing aid, shielding them without affecting their performance. The application process, which is done in a vacuum chamber, ensures global coating of all components inside and out. Liquids or moisture coming into contact with the hearing aids simply roll off without being absorbed.
Because moisture related failure is one of the main causes of hearing aid returns, the innovation has had a dramatic impact on product reliability. ReSound said that in a review of 50,000 hearing aids sold in the first six months since its introduction, it found that the iSolate nanotech protective coating decreased moisture and debris related repairs by 50 percent. This data show promise that indeed the Resound isolate nanotech protective coating introduced in their new hearing aids are effective at reducing hearing aid repairs.
The Future of Reducing Hearing Aid Repairs
We can expect to see more announcements like these–although ReSound is the first manufacturer that author David Copithorne of the article Resound’s Water Resistant “iSolate Nanotech” Coating is on Cutting Edge of a Revolution in Hearing Aid Materials has seen who has actually documented the benefits of new materials by tracking a reduction in repair rates–because reliability is a critical factor in the success of any new in-ear or behind-the-ear product.
Any audiologist or hearing aid designer can tell you that the inner ear is one of the most hostile places on the planet for miniature, high-performance, digital electronic devices. It’s wet, humid, and full of potential infectious agents. And because the devices themselves are so tiny, they are far too easy for large human fingers (especially for those of us who are “all thumbs”), to drop on the floor and otherwise abuse. Therefore the space-age materials that are making today’s hearing aids more durable and comfortable than ever before may be as important to their acceptance by more users as their ability to provide high-quality amplified sound.
