Understanding How Hearing Aids Work and the Technology Available

For some people, not being able to understand conversations that are going on around them can be troublesome. Not only do you miss critical information, but also misunderstanding what is being said can adversely affect your relationships. There are solutions to your problems.

Before you can be tested to see if you need hearing aids Adelaide, you must first get past the hurdles that keep you from going for testing in the first place. Many hold out thinking that only older people wear these devices. They may believe that being at the peak of their careers means they aren’t negatively affected by their inability to comprehend what is going on around them. You could be one of those people who are okay with the loss. Your aversion could also stem from not understanding how these devices work.

How hearing aids work

It can be confusing to get to know the intricacies of how these small systems work. They are highly sophisticated and come in many different forms because there are different audiological problems that people face. However, no matter how complex the device, they all share five essential components that work together to amplify sound.

Hearing aids all have a microphone built in them. This part picks up sounds throughout an area. The sound is then transmitted to a processing chip. This chip analyses the signals the receiver caught. Once the noise is processed, it is sent to the amplifier. The amplifier magnifies the sound and transmits it to a loudspeaker. The speaker then broadcasts the sound into the inner ear. The inner ear turns the received sound into electrical impulses, which are then picked up by the brain and processed.

The process sounds like it would take hours to complete. In reality, that complex relay system works in a matter of seconds.

Available technology

While all devices have some of the same fundamental components, there are several different ways for the sound to make it to the inner ear. Some of these systems have a small wire that is placed directly in the ear. Others use a tube connected to an earmold, which feeds into the ear. Some are small enough to fit right in the canal with no additional wires.

While the size and style may differ, there are only two ways for the sound to be processed. It can be either analogue or digital.

In analogue apparatuses, the sound is processed as an electric signal received by the microphone, and then the sound is copied. However, with these gadgets, the copy is limited, and some deterioration occurs.

In digital equipment, the signal is converted into binary digits which are processed similarly to the analogue variants. However, because the digital signal is simplified to 0s and 1s, it can be repeated endlessly with no deterioration in the signal.

While it may seem that digital hearing aids Adelaide are the obvious choice for some, they don’t work as well for others. Your audiologist can help you determine which option meets your needs and your budget.
