On average, otoplastics last for 5 years. Because the outer ear changes differently and at different rates for everyone, the individual lifespan can vary greatly from person to person.
That is why we recommend performing an annual leak test instead of replacing the otoplastics after a fixed number of years. This has two major advantages:
- Safety: You prevent someone from walking around with leaking earplugs for years (false sense of security).
- Cost savings: You only replace the otoplastics when they really no longer seal properly, and not unnecessarily early.
The maintenance session will be completely useless without the users. The most important part of the maintenance is the leakproof test. During this test, the product specialist tests whether the otoplastics still blocks the ear canals adequately. In addition to this, the dialogue between the user and the product specialist is very important. Based on the experience, adjustments, such as the damping, can be made.
The external anatomy of the ear changes in a unique way and speed with each person. This means that the otoplastics of one person already leaks after 2 years and of the other only after 8 years. For example, if a company decides to replace all otoplastics after 5 years, the first person will have walked around with leaking earplugs for 3 years with the associated harmful consequences. With the second person, the otoplastics are replaced unnecessarily and the company incurs unnecessary costs. It is therefore strongly recommended to test otoplastics for leak-tightness at least annually. In addition, during a maintenance appointment, a dialogue is created between the specialist and the user, and any problems can be addressed and resolved.
