Frequently asked questions hearing protection
1. When is it advisable to wear hearing protection?
In general, it can be said that being subjected to noise levels of 80 dB(A) or less for eight hours a day is not harmful. You can recognise that the level is 80 dB(A) when you have to raise your voice to be understood by someone standing only 1.6 feet away. The level is then at least 80 dB(A).
The safe exposure time halves with every 3 dB(A) increase. So it is only safe to be exposed to a noise level of 83 dB(A) for four hours and to a noise level of 86dB(A) for only 2 hours! If the noise level is even higher than that or the exposure time is to be longer it is certainly necessary to wear hearing protectors to exclude the risk of damaging your hearing.

2. Why choose custom-made hearing protection?
Custom-made hearing protectors have many advantages. In the first place, they are comfortable to wear. After a while you won't even notice you're wearing them. At the same time they provide maximum protection. Our broad range of sound filters makes it easy to choose the right protection. Custom-made hearing protection enables you to continue communicating with others as normal and there is no need to worry about feeling pressure in your ears. In short: a custom-made hearing protector is the ideal solution for all noisy situations.

3. What is the difference between a 'hard' and a 'soft' hearing protector?
Soft hearing protectors, made from silicone material have only been on the market for a few years. They are comfortable to wear in the ear and adjust to the movements of the auditory canal, as the wearer talks for example. This hearing protector therefore seals the ear better than a hard one.
Hard hearing protectors are made of acrylic. These are the oldest and most well-known form of custom-made hearing protectors and are very easy to place in the auditory canal. In many cases, a hard hearing protector is the best solution for people with a very narrow auditory canal.

4. How long will EXINORE hearing protectors last?
EXINORE hearing protectors last on average for four years. This life span does not depend on the quality of the hearing protectors, because that is monitored extremely carefully, but on the auditory canal. During our lives, the auditory canal continuously changes shape. This change can result in a hearing protector not fitting as snugly, not sealing properly and therefore making the attenuation insufficient. To ensure the best possible protection, it is therefore necessary to be measured for new hearing protectors every four years. The recommended replacement date is shown on the grey card with your customer details, which you will receive at the same time as your hearing protectors.
close question
5. When are ears 'fully grown'?
The shape of our auditory canal changes throughout our lives. That is why we can only give our hearing protectors a life span of four years. But the biggest change occurs in children, so if you are still growing, the life span may be shorter than four years.
close question
6. Are EXINORE hearing protectors tested?
All EXINORE hearing protectors are tested, certified and provided with the European CE identification mark.
A hearing protector is a product that is "legally" covered by the "personal means of protection" guideline. That means that this product must be extensively tested by a certified institute (TNO, for example). Only if it meets all the requirements will it be given the CE identification mark and accompanied by a detailed manual listing all its specifications. If a hearing protector does not carry the CE identification mark, the product has not been certified.
close question
7. I find it difficult to insert the hearing protectors. What can I do to make this easier?
When a hearing protector is new, it can be more difficult to insert into the auditory canal because it lacks flexibility. In that case, we advise applying a little Otoferm ear cream to the part that is to be worn in the auditory canal.
close question
8. I'm experiencing pain. What now?
If your ears are painful, it's best to go and see your hearing specialist. He or she will send the hearing protectors back to us, generally accompanied by a new mould of your auditory canal. Our production department will look at the moulds and decide whether or not an adjustment is needed. In some cases, we will supply a new hearing protector.
close question
9. How much noise can EXINORE hearing protectors suppress?
The EXINORE product range offers a whole raft of filters and filter types. You can see which type of filter is the most suitable for which hearing protector by looking at
our list of products on this site. Your hearing specialist can also give you extensive information about this.
close question
10. Is it true that the best filter is always the strongest one?
That is a misconception. Too much attenuation is just as irritating as too little. It cuts you off from the outside world and increases the risk of dangerous situations occurring: in traffic, for example.
close question
11. Can I try out the hearing protectors before I buy them?
No. These are individually custom-made products and therefore they cannot be physically tested before you buy. What you can do, is experience the advantages of the different types of hearing protection in our
sound matrix.
close question
12. I am allergic to acrylic and silicone material. Is there another solution?
Both our soft and hard hearing protectors can be treated with a special anti-allergy lacquer. If this does not work, or insufficiently, then unfortunately your ears are unsuitable for hearing protectors.
close question
13. Can I claim the cost of hearing protectors on my health insurance?
No. Because hearing protection is seen as a preventative measure, no insurance covers them.
close question

16. How long are the moulds of auditory canals kept?
We keep the moulds for eight weeks. Heat and cold can cause the moulds to become deformed. When they do, it is no longer possible then to produce a good quality hearing protector. This is also the reason why we do not return moulds.
