1. Custom manufacture of ear tips.

Custom earmolds are moldable tips that are often used at work.

Foam ear plugs are good for occasional users, but if they are not inserted properly, they do not provide ideal protection. The earmuffs can, in the long run, be hot and uncomfortable. And if for reasons of discomfort, the protections are removed in a noisy environment, the preventive effect becomes null. That’s why a new generation of earmolds with filter has been developed that protects the hearing with filter that lets the sound.

Despite their high cost, they have been adopted in many companies because they are comfortable to wear for long periods. However, according to the American Society of Safety Engineers, their effectiveness has been questioned in the past, but significant efforts have been made since then, improving design and efficiency.

2. Review of the hearing.

How to pass a hearing test? A hearing test often consists of a series of exams and tests, which together determine whether a person is deaf and the severity of the problem.

The audiologist will often start by asking you a few questions to better understand your hearing problems. For example, they may ask you if you have been exposed to loud noises or if other members of your family have a hearing loss. Your answers will help determine the extent of the problem and possibly identify other disorders that may require special attention.

Initial examination

After this first interview, the specialist will probably examine your ears with a special instrument called an otoscope. This examination will allow him to determine if the loss of hearing is due to an injury to the ear canal or eardrum.

Then comes the moment of the global hearing test, performed in a closed and soundproof room.

Introductory tone audiometry

The first test is threshold tone audiometry. This test examines your hearing ability by making you listen to a series of pure sounds using headphones or headphones.


In some cases, the hearing health professional performs an impedancemetry to measure your ability to hear pure sounds by placing a transmitter behind the ear. Impedancemetry reveals whether there is a problem in the middle ear cavity.

Voice audiometry

Then, the hearing health professional tests your ability to hear the spoken word. This test is used to assess whether there are problems with the auditory nerve, which sends signals from the ear to the brain, and to check if there are problems with the brain with regard to understanding of speech.


The last exam is tympanometry. Tympanometry verifies the condition of the middle ear and the mobility of the eardrum.


The results of the tests are presented on an audiogram that allows you to define your degree of hearing loss and whether the use of hearing aids would be beneficial.

3. Adjusting digital hearing aids.

Hearing aid technology is constantly evolving and becoming very advanced. Modern hearing aids are small, hi-tech computers that are constantly being developed and refined to reproduce as accurately as possible a natural human hearing.

These advances allow for many options and better sound reproduction. The ability to adapt the device to individual demand while taking into account the environment and the specific needs of a type of hearing loss is constantly improving.

More programming

Modern digital hearing aids constantly analyze the sounds in your environment and alternate between the various pre-programs, automatically choosing the optimal programming adapted to the specific needs of a situation.

The reproduction of the sound is constantly adapted by the hearing aid to provide you with the best possible hearing.

At Audio Link you will find a service after sales answering your satisfaction.

Many hearing impaired people find it difficult to hear what others are saying on their mobile phones – the solution may be Bluetooth hearing aids.

Mobile phones and hearing aids

Mobile phone systems can cause electrical interference in hearing aids, which can cause a lot of disruption. Interference varies with a number of factors, including the phone model and the type and model of the hearing aid. These problems make it difficult for many hearing aid wearers to make good use of mobile phones.

Bluetooth technology

Today’s most advanced digital hearing aids are Bluetooth and wireless compatible and are therefore able to connect to various Bluetooth devices, such as mobile phones, computers, radios, MP3 players and TVs – these devices must only be connectable to a Bluetooth network.

Bluetooth technology is a wireless process of exchanging and transferring data between two electronic devices that are in close proximity to one another. Most solutions consist of a streaming device. This device transmits the received Bluetooth signal to the hearing aid and therefore must always be near the user of the hearing aid.

Handsfree headset

Bluetooth technology allows people with hearing loss to hear the output more clearly, as sounds are transmitted to both hearing aids at the same time, which, among other things, makes talking by mobile phone easier. In addition, the streamer makes it possible to set up and receive calls using the Bluetooth hearing aid without even touching the phone. This essentially means that Bluetooth technology turns hearing aids into a hands-free kit and gives the user free access to all connected Bluetooth devices.

To use these features, hearing aids must have Bluetooth connectivity as it can not be installed later on a device. In addition, it is important to always try a new mobile phone before buying it.

5. Repair of hearing aids.

All hearing aids consist of the same essential elements.

The components of a hearing aid

These are integrated in a protective case, usually plastic.


The first major component is the hearing aid microphone that picks up sounds in the air to convert them into electrical signals.


The hearing aid amplifier increases the intensity of the signals picked up by the microphone. Filters modify sounds to amplify only useful sounds.

Loud speaker

The third basic constituent is the ‘loudspeaker’ (receiver). It converts electrical signals into acoustic signals that are perceptible to the user.


The three elements we have just listed are present in all hearing aids. The digital hearing aids are also equipped with a programmable microprocessor, which “autocontrols” the signals according to the type of deafness of the wearer fitted with the hearing  device.

Some hearing aids are equipped with control functions for individual adjustment.

Many hearing aids have remote controls, making adjustments especially for people with dexterity problems.

The special batteries needed by all hearing aids come in different sizes and capacities. A standard battery has a life expectancy of between 5 and 14 days, depending on the type of hearing instrument, the capacity, the type of battery and the intensity of use of the hearing aid.
