The amplifier is defined as the internal component/part of the hearing aid that plays a fundamental role: converting sound into an electrical signal and sending it to the receiver/speaker. Indeed, it is the amplifier that enables people wearing hearing aids to hear more clearly and understand sounds better.
A hearing aid is a small electronic device designed to improve the hearing experience. Externally it mainly consists of:
Internally, the amplifier analyses incoming sounds and adjusts them to the user's specific hearing needs. Another essential component is the battery. Designs may vary, but most modern hearing aids are discreet and comfortable to wear, often fitting perfectly behind or inside the ear.
Amplifiers work as a bridge between the microphone, which captures the sound, and the loudspeaker, which transmits the amplified sound to the ear.
Therefore, they are an indispensable component for the proper functioning of the hearing aid. They convert soft sounds into audible sounds, thus enhancing the hearing experience, and can perform up to 48,000 operations per second.
The science behind amplification is fascinating: it is a process that transforms sound waves into enhanced electrical signals.
So as we have already mentioned, everything starts with the microphone, another extremely important internal component of the hearing aid. These electric signals from the microphone are sent to the amplifier, which is located inside the hearing aid, which increases their strength and makes them more audible. It is certainly a very complex process that is adapted to every type of hearing loss. The degree of amplification can in fact be adjusted according to the user's specific needs and preferences.
n recent times, considerable progress has been made in the development of hearing aids and amplifiers, which have radically changed the hearing experience of people with hearing loss.
One notable advance is the incorporation of digital signal processing (DSP) technology, which enables amplifiers to provide clearer and more authentic sound quality while reducing background noise.
Furthermore, it is essential to recognise the central role of microphones in the functionality of amplifiers; directional microphones, in particular, have seen significant improvements. Furthermore, telecoil technology has revolutionised the connectivity of hearing aid amplifiers, facilitating seamless integration with various audio devices such as smartphones, televisions and voice assistants, thus improving communication and accessibility options.
Although technology undoubtedly plays a key role in the development of hearing aids and amplifiers, the expertise of a qualified audiologist is invaluable when it comes to selecting these devices to meet specific needs.
Every person has a different degree of hearing loss, a different ear shape and different needs. That is why we recommend you book an appointment with our Amplifon experts to receive personalised recommendations based on your preferences and lifestyle to find the best hearing aid for you. In addition to choosing and fitting the device, audiologists provide ongoing support, advice and training to help people adapt to their new hearing aids and maximise their benefits. Fitting, revision and cleaning appointments are also of equal importance.
Maintenance of the hearing aid amplifier is crucial to ensure its longevity and optimal performance. Proper care and regular maintenance not only prolongs the life of the device, but also improves its functionality, enabling clear and reliable sound. By implementing simple but effective maintenance practices, such as regularly cleaning your device with a soft, dry towel and storing it in a protective case when not in use, you can prevent moisture build-up, the accumulation of detritus and potential damage.
In addition, by being alert to signs of wear and tear and addressing any problems promptly, you can prevent minor issues from turning into more significant problems. Always consult your hearing care professional, visit your nearest Amplifon centre.
