A hearing aid is a small electronic device that can be fitted to your ears either on the inside or outside to help amplify sound and improve your hearing ability. Hearing aids can be incredibly helpful and they are used for people of all ages to improve hearing and improve quality of life. 

Hearing aids are incredibly useful and small enough to wear inside or behind the ear, allowing you to go about your day with almost no disruption. 

How Does a Hearing Aid Work? 

The process for how a hearing aid works is simple. First of all, a microphone will pick up sound from the surroundings. Secondly, an amplifier makes the sound louder which will make it easier for your ear to process on the other side. And then finally a receiver takes this amplified sound and sends it into your ear. 

Types of Hearing Aids

When looking for a hearing aid that works for you, it is important for you to work with a hearing instrument specialist who will be able to talk you through your options and find one that works with your lifestyle. The type of hearing aid you get depends on a few different things. Your age, the reason for your hearing issue, your lifestyle and the cost. 


Digital hearing aids will convert sound waves into computer code and then this is amplified. These hearing aids can direct information about pitch and volume to ensure that the sound quality you hear is better quality. 

Hearing aid styles 

There are three main hearing aid types that most people choose between for their aids – in-the-canal hearing aids, in-the-ear hearing aids and behind-the-ear hearing aids. 

  • In-the-canal (ITC) hearing aids fit specifically to your ear canal.
  • Completely-in-canal (CIC) hearing aid is almost completely hidden inside your ear. Both of these types of hearing aid will help those who are suffering from mild hearing loss. 
  • In-the-ear (ITE) hearing aids are completely inside your outer bowl and they are almost invisible to see. These are great for adults who are a little more active as they won’t be as likely to fall out, and they are ideal for those who have severe hearing loss and need the extra help. 
  • Behind-the-ear (BTE) hearing aids are ideal for children whose ears are still growing and they sit with part of the hearing aid over the ear, and part hanging behind the ear. This one is the easiest to fit and remove and although more visible, they are great for preventing earwax buildup as well as ensuring voices sound clear when speaking.
