Hearing Aid Amplifiers - How do Hearing Aids Work?When put into simplest words, all the hearing aids, in general, works as small amplifiers. Thanks to the developments of the modern technology, these hearing aid amplifiers can be manufactured to suit the requirements of different types of patients seamlessly. Every hearing aid comes with three main parts no matter if they are digital or analog. Nevertheless, read on this article if you are wondering how the hearing aid amplifiers work.

– Sound detection

Forefront part of any hearing aid is nothing but the microphone. This is the part that detects the sound waves approach the listener (wearer). However, microphones with analog technology differ from the digital ones when it comes to clarity of the captured sound. For instance, when you are in the midst of a noisy crowd, analog microphones may find it difficult to distinguish one sound from another. In contrary to that, newer hearing aid amplifiers come with digital microphones that are capable of capturing the sound comes towards the listener rather than the background noise. Although perfect background noise cancellation is a difficult task, products come from renowned brands are capable of delivering exceptional results for the listener.

– Circuitry

Once the sound is captured from the microphone, the respective sound will be sent to the deeper circuitry. In fact, the captured noise will be processed within this circuitry. This is where most of the work is done. Modern digital hearing aids focus more on distinguishing important sounds and facilitate the wearer to spend a normal life within the society. These modern circuitry units are capable of distinguishing the necessary sound waves and amplifying them quite effectively. After the amplification process, the wearer will be able to hear the sound due to the increased decibel levels. In fact, because of this amplification process, some people opt to compare this process to the work of a magnifying glass; it amplifies the captured volume and helps the wearer to hear a stronger sound. The amount of amplification might differ depending on the severity of the hearing loss of the wearer.

– The Receiver

Now that the microphone has captured the sound and it is amplified with the help of the circuitry, it is about delivering the amplified sound to the listener. In fact, the receiver works just like a phone’s receiver; it delivers the sound directly towards the user’s ear.

– The battery

In general, hearing aid amplifiers don’t work without a power source. The obvious power source of the digital hearing aids is batteries. Most of these devices come with small sized batteries. Because of this small size, you cannot expect them to have exceptionally longer life spans. However, depending on the brand of the device and the model of the battery, the lifespan may slightly vary. You need to consult a specialist identify the exact situation of your ear before you purchase a hearing aid. Make sure you go for a reliable brand and model that delivers what you precisely expect.
