Hearing Aids

There is a multitude of hearing instruments and technologies available on the market today. The design of hearing aids varies tremendously but the purpose remains the same for every device: empowering you to live and enjoy your life to the fullest.


We believe that independent and professional advice is imperative to match the ideal hearing solution to the unique needs and requirements of every individual.

At Farnham Hearing we have access to wide array of great hearing aid technologies and styles,  enabeling us to tailor the need of each patient with the appropriate system, instead of fitting a patient to an available system with limited results.


Our fitting procedures adheres to the standards for practice for Audiological procedures as set out by the British Society of Audiology and this includes recording real-ear-measurements. These tests or NOT readily performed on the high street. Read more on how we ensure the ideal fitting on our dedicated page below:: ​ ​

How does a hearing aid work?

While there are many different types and levels of sound processing available, all hearing instruments share five basic components:

  • A microphone that picks up sound

  • An amplifier that makes the sound louder

  • A tiny computer chip that processes and improves the quality of the sound to suit your hearing needs

  • A small loudspeaker that sends the improved and amplified sound to the ear

  • A battery that powers the whole device


Although the overall design of hearing instruments varies from model to model, it is the technology inside that makes the real difference. The technology or brain of the hearing aid determines how smart and adaptable it will be.  More sophisticated the technology will provide a richer and more rewarding listening experience to the wearer of the hearing aid.

What kind of hearing aid technology is available?

Analogue Sound Processing

Analogue sound processing is the most basic hearing aid technology. While this technology is the cheapest option it does come with certain drawbacks. It can be compared to making an enlarged photocopy of a small photo. While you end up with a bigger picture, you will have lost many of the finer details in the process.


Digital Sound Processing

Digital hearing aids convert the acoustic signal into a digital format (ones and zeros) before the sound is processed. It’s then converted back to an analogue acoustic signal for the listener. In contrast with analogue sound processing, the overall quality is not adversely affected but enhanced.


Wireless Communication

Recent advancements in hearing aid technology have resulted in superior wireless connectivity and high-speed broadband communication between instruments. This enables two hearing instruments to communicate and perform binaural processing, allowing them to work as one central processor. This mimics the way our brain naturally processes sound from both ears. The left and right hearing aid works together and improves hearing particularly in challenging listening environments like group conversations. The technology provides a more authentic listening perspective.


In addition, hearing instruments can also connect to a number of Bluetooth-enabled electronic devices like mobile phones and MP3 players. This means that the wearer will be able to receive a telephone call directly in their hearing aid. This is like an upgraded hands-free kit for your mobile. Not only will you benefit from more refined amplification (no sound lost in translation from the telephone speaker to the hearing aid microphone), but the caller’s voice is heard in both ears!
