How do Hearing Aids Work and what do Hearing Aids do?


Most people take their ability to hear for granted, but those who have ever suffered from long term hearing loss will know just what an impact this can have on quality of life. Unfortunately, there are many people who suffer from hearing loss. While this is something that many people associate with old age, hearing loss can occur at any age and due to one of a range of reasons, not just due to age.

There are a number of different solutions and options available to those who suffer from hearing loss. The options available will depend upon factors such as the level of hearing loss, the cause of the problem, and the age and medical history of the patient. One effective solution used by many who suffer from hearing loss is the use of a hearing aid.

What is a hearing aid?


Hearing aids are very small electronic devices, and they are simply worn either inside or behind the ear in order to enhance audio. For those who suffer from reduced hearing and struggle to hear on a day to day basis, these aids provide a convenient, simple and affordable solution to help them to hear more clearly. With a hearing aid, you should be able to benefit from enhanced audio both in noisy and quiet settings, which means that you get to enjoy a far greater quality of life and fuller participation in day to day activities.


What are the different types of hearing aids?

There are a few different types of hearing aids that can be worn by those who suffer from hearing loss. This includes:


  • An aid that fits behind the ear (BTE): A common version of the hearing aid is one that loops over the ear and sits behind the ear in order to enhance audio. You can get a full sized aid or a mini version of an aid to sit behind the ear.
  • An aid that fits inside the ear (ITE): Another version you can get is an aid that sits inside the ear. These are fitted completely into the outer ear rather than sitting behind the ear.
  • An aid that fits into the ear canal (In-The-Canal, or ITC), with the receiver in the canal (RIC) or Completely-In-Canal (CIC): There is also a hearing aid that can be fitted into the canal of the ear. These are moulded and created to fit the specific shape and size of the individual’s ear canal.


How hearing aids work

There are three main parts to a hearing aid:

  • The microphone
  • An amplifier
  • A speaker

The sound waves received by the microphone are converted into electrical signals which are then amplified by the amplifier and fed back into the ear through the speaker. Some hearing aids are able to tell the difference between quiet and loud sounds, and can differentiate between sounds which need amplifying, and those that don’t.


How hearing aids can help


The aim of any hearing aid is to improve sound and audio for anyone that suffers from long-term mild to severe hearing loss. They are able to assist with the comprehension of speech in those who suffer from hearing loss, and they can have a significant positive impact on your day to day quality of life, the activities that you get involved in, and even on your social life. Through magnification of sound vibrations that enter the ear, these hearing aids are able to make a big difference even if you suffer from severe hearing loss.
