Hearing protection

Why do I need to protect my ears?


Many factors such as noise, water, altitude... can affect your hearing and disturb your comfort. For example, being exposed to noise causes irreversible hearing problems and other harmful effects such as stress, insomnia, anxiety... Wearing hearing protection will eliminate these discomforts and protect your hearing.

❗ According to the World Health Organization, 1.1 billion people are at risk of hearing damage due to harmful noise levels (nightclubs, concerts, bars and other events).

1.1 billion people are at risk of hearing damage due to harmful noise levels




What sound level can cause hearing damage?


🔊 The decibel (abbreviation "dB") is the unit that measures sound level. Irreversible hearing damage can occur from more than 8 hours of exposure to 85 dB. A concert can easily reach 100 dB. Without hearing protection, your ears can suffer irreversible hearing damage (hearing loss, tinnitus...) after only 15 minutes!

More than 1 in 10 people have permanent tinnitus (ringing or buzzing in the ears). 7 out of 10 people have experienced tinnitus after a festival. This problem is due in particular to a lack of awareness of the irreversible hearing consequences of high sound exposure. Since our hearing is essential to our social life, it is therefore more urgent to take care of it.

The higher the sound intensity, the shorter the maximum recommended exposure time. Find out the maximum exposure time based on sound intensity below.

Noise level scale decibel exposure time




What is the difference between standard earplugs and custom made earplugs?


Standard earplugs are uncomfortable and do not fit properly in the ears, allowing harmful noise to enter and damage your ears. Even if you wear standard earplugs, you will never be properly protected because they will never fit perfectly in your ears. This is because the shape and size of each ear is unique (like fingerprints!).🧐 Did you know that even your left and right ear are different?

Custom made earplugs fit perfectly the shape and size of your ears. Those kind of earplugs never fall out of your ears, offering you an ultimate comfort and a perfect protection. Unlike foam earplugs that muffle sounds, some of our custom earplugs (only with filters) reduce harmful sounds while maintaining a perfect speech and music quality. Discover in the table below the advantages of custom earplugs compared to standard hearing protection.

Will decilo earplugs stay in my ears?


Yes of course! Unlike standard earplugs, decilo earplugs are molded to the precise shape of your ears offering a perfect fit. Forget the days when your standard earplugs fell out of your ears. Your decilo earplugs won't move in your ears.




How long can I use my decilo earplugs?


Thanks to the high quality materials that we are using, our earplugs are durable and reusable for many years (or even forever 😉). If you take care of your ear plugs, you will certainly be able to use them for more than 5 years. In this way, you will contribute to preserve the environment.

Our ears continue to change slightly throughout our lives. For this reason, we recommend to check the fit of your earplugs (especially for children or people who have a significant weight change). Depending on the fit of your earplugs, we advise you to renew your earplugs after about 5 years by taking new ear impressions.




Are decilo earplugs reimbursed by health insurances?


Yes, some health insurance companies reimburse up to 50% of the price of custom made earplugs. We invite you to contact your health organization directly for more information on a potential reimbursement. You do not need a medical prescription to be reimbursed. We will provide you the necessary documents.




Do decilo earplugs need to be recharged?


No, there are no electronics in our earplugs. All the magic of attenuation and protection is done passively. You don't have to worry about batteries.




Is it possible to do a hearing test?


Yes, you can do a free hearing test to check your hearing in our store or in one of our dealers’ stores. Please specify this when you make an appointment.




What is the purpose of the leakage test? (for earplugs with filters)


leakage test earplugs

Checking the fit and tightness of custom made earplugs with filters is essential to guarantee a perfect protection and an optimal acoustic quality. A custom made earplug that is not perfectly fit can reduce attenuation performance by more than 10 dB, making the user susceptible to hearing damage. This simple test, which lasts less than 5 minutes, can be performed by us or by one of our dealers. We advise you to have your earplugs checked once a year.




Are filters of the earplugs interchangeable? (for earplugs with filters)


Yes, absolutely! You have the opportunity to easily change your filters according to the sound intensity of your environment. You can change your filters yourself in a few seconds. This is ideal for combining different situations (going to concerts and working in a loud noise environment for example) without having to buy new earplugs. Discover the range of our interchangeable filters in the Accessories section.




I have tinnitus. Can decilo earplugs help me?


decilo earplugs are designed to protect your ears for a specific application. Some of our earplugs (especially those for music) are specially designed to protect you from noise while maintaining excellent sound quality. They prevent the development of your tinnitus, but are not an appropriate remedy for existing tinnitus.




I suffer from hyperacusis. Can decilo earplugs help me?


Yes, that's right. Some of our earplugs (especially those for music) are specially designed to protect you from noise while maintaining excellent sound quality. They are therefore very suitable for people with hyperacusis (or who have an increased sensitivity to noise). decilo earplugs will allow you to continue to live normally without being disturbed by high noise levels (public transport, restaurants, noisy streets...).




Can wearing earplugs give me an ear infection?


No! Wearing custom-made earplugs cannot cause an ear infection. In addition, all of our custom earplugs are coated with an antiallergic coating.




How do I use and clean my decilo earplugs?


Our earplugs are easy to use and clean. We include a user manual with each order detailing how to insert, remove, clean and maintain them.

Insertion: You must first make the distinction between the earplug for your left and right side. The left earplug has a blue dot on it. The right earplug has a red dot. Grasp your earplug with your thumb and forefinger (with your hand on the same side of your ear) so that the colored dot is facing up. Keeping the colored dot facing up, insert the earplug into the ear canal (inner part of the ear). Then push the earplug into your ear with your index finger, making small forward and backward twisting movements. During this step, you can open your mouth to make it easier to insert the plug into your ear.

Removal: Grasp the hearing protection with your index finger and thumb. Pull your earplug outward. To make removal easier, we recommend that you rotate your hearing protection forward.

Cleaning & Maintenance: Your earplugs can be easily cleaned with soap and water using a damp cloth or a hygienic wipe. It is not necessary to use an antibacterial product or alcoholic wipes. Chemical detergents and compressed air should be avoided as they are harmful to the product. Then let your earplugs dry in open air at room temperature. Never heat your earplugs to dry them. After each use, we advise you to store your earplugs in the box or safety pouch provided.

For earplugs with filters, we invite you to remove any earwax that may be in the canal of the earplug using the earwax removal tool provided. This step must be done carefully to avoid touching the acoustic filter or damaging it. Never touch the filter with sharp objects or brushes as this may damage the filter membranes. The filter should generally not be cleaned. If a more thorough cleaning is required, remove the filters from the earplugs and shake them in tempered water. Then rinse your filters with clean water and leave them to dry in open air at room temperature.




How to effectively protect your hearing?


Here are 3 tips to protect your hearing:

  1. Delete, reduce or move away from the sound source: The sound intensity drops by 6 decibels when you double the distance from the sound source. For example, if you are at 20 metres from a speaker and you move 40 metres away from it, the sound intensity will drop by 6 decibels.

  2. Take breaks: If your ears are exposed to high sound levels for long periods of time, it is important to take regular breaks in quiet places to give your ears a rest.

  3. Protect your ears: There are different solutions to protect your ears. Standard earplugs (disposable or reusable), headphones and custom fit earplugs. Custom fit earplugs are by far the best and simplest solution to protect your ears and prevent hearing damage (hearing loss, tinnitus...). It is the only solution that protects your ears 100% and offers an absolute comfort. The custom fit earplugs are discreet, easy to use and can be used for more than 5 years. Thanks to the acoustic filters, the sound quality of music and speech is perfectly preserved.

Do I need a medical prescription to make custom fit earplugs?

We are certified audiologists and our custom fit earplugs are approved according to the European guidelines. Several health insurances are paying back a part of the price of the earplugs.
