Hearing aids are battery powered devices that convert the environmental sounds into electronic signals. They alter the signals by performing and applying millions of operations per second to enhance them. Finally the enhanced signal is then converted back to sound so that a rich environment can be heard by the ear and it all happens so quickly that the user is not even able to sense the time difference.

A hearing aid is a medical device that is manufactured to strict standards by reputable and quality controlled manufacturers. The design and technology incorporated into such hearing aids is strongly based on scientific evidence, testing and research. Naturally then a hearing aid should and will be custom made and custom fitted.

Hearing aids require careful fitting to ensure that the output of the instrument is safe and appropriate for the user, that its features are programmed in such a way that takes into account the user´s daily environments and personal and individual listening needs.

There is a considerable amount of confusion about hearing aids and it is a common mistake to think that hearing aids only amplify sounds, the section below should help to understand why this is not so.

Basic Facts


Noise of sufficient volume and duration can cause temporary chemical changes at the cellular level in the cochlea and can lead to permanent damage of the cochlear hair cells.

Men and women who are exposed to loud noise during their working day develop gradual, permanent loss of hearing often accompanied by tinnitus.

Hearing loss and tinnitus resulting from excessive exposure to noise, cannot be medically orpharmacalogically repaired.

As a guide: asustained exposure to sound level of 90-95dB can result in permanent damage of the delicate inner ear structure.

Exposure to noise that exceeds the safe standards has also been found to be associated with stress and fatigue.

Comfort may be poor with generically designed ear protection and insufficiently effective.

Custom-made earplugs are shaped to the individual ear, are effective inconspicuous, easy to look after, clean and take out.

Are memories that can be programmed into the hearing aid´s brain, so that upon changing environments the user can benefit from immediate change in sound quality to increase comfort and speech intelligibility.

Binaural coordination

The user of two hearing aids is able to change the settings on both devices, by touching only one. The aids communicate with each other wirelessly to ensure users immediate comfort.


A hearing aid can be set to remember the users setting preferences for loudness in different environments, remember these preferences, recognise the environment and adjust dynamically.

Automatic phone detection

When a phone is lifted towards the ear with automatic phone detection enabled hearing aid, the hearing aid will switch to receive the electromagnetic signal from the phone, thereby reducing the possibly interfering sounds within the listener´s environment.

Transient noise reduction

Sudden loud sounds can be very uncomfortable sometimes even more so to those with poorer hearing sensitivity. A hearing aid user with this feature on board need not worry, as his hearing aid will suppress this sound very quickly, preventing it from causing discomfort or damage to hearing.

Feedback management

Feedback is an unwanted squeal that surprised the user and those close to him often in inopportune moments. Feedback in current instruments is no longer the concern it used to be as the hearing aid listens for it, determines its properties and suppresses it with great speech and efficiency.

Speech enhancement

Speech is a unique signal, different for each speaker and different to all other sounds in our environment. Speech is of utmost importance almost always: to hear a joke, not to miss out on an order being repeated incorrectly in a cafe. Recognising speech amongst all sounds in the environment and improving its clarity without enhancing the unwanted sounds is the aim of the artificially intelligent hearing aids.

Wind noise management

The sensitivity of the hearing aid´s microphones can be exploited by the wind, which in turn interferes with conversation that is occurring between two friends going for a walk. Special care is taken by the hearing aid to reduce its microphone sensitivity to the wind noise, enhancing the user´s comfort when he is outside.

Data logging

Allows the hearing aid to retain information about the hearing aid´s use, the number of hours, the listeners program preference and other important details that help the clinician better understand the user´s listening preferences and needs..

Wireless connectivity

Most are familiar with the difficulty of hearing on the phone in a room with talking voices, or trying to hear the dialog on TV when others are talking to each other nearby. Current devices are being designed in mind with these common difficulties, connecting the listener with technology that is being used many times every day perhaps with frustration. Taking the frustration of trying to hear on the phone, the TV, at a conference, in a meeting by direct, wireless sound transmission and allowing for hands free adjustment to the sound intensity and quality with discreet remote controls..

Lifestyle profiling

Current hearing aids are constantly "thinking" about the environment of the user. They are trying to define where the person is: Is she at a gathering and dining with friends and family? At a theatre performance perhaps? Watching the evening news? In the office working at her desk? Constantly listening, classifying and applying enhancements to some sounds and suppressing others to keep its user comfortable and hearing clearly.e.

Automatic adaptation

Wearing something new for the first time can make one a little self-conscious until you get used to it. With automatic adaptation you don´t have to "get-used to it". A device with this feature will slowly adjust itself to you as you adjust to it, making the initial discomfort usually treated with "it will take time to adjust" unwarranted.
