Do you Know How the Hearing Aid Works?

When hearing loss is confirmed, several solutions are available to regain the pleasure of hearing. One of the first is hearing amplification devices. But how do hearing aids work? While many models and technologies are available on the market, few people know the ins and outs. However, basic notions in this area can help to see more clearly and, possibly, to hear better.

In addition to the types of technology and the different models (earloop, in-ear, etc.), each device is composed of 4 key elements:

  1. A microphone;
  2. A speaker (or earphone);
  3. A battery;
  4. An amplification system (the computer).

The latter is carefully programmed by a hearing care professional to correct, as precisely as possible, the hearing loss specific to each patient. It is here that the work of a conscientious professional makes all the difference. The professional will then adjust the device to amplify and / or transform the different problematic frequencies.

Sound amplification steps: how is this going?

1th step
Sound stimuli are first picked up by a mini-microphone.

2th step
The computer analyzes the sounds received and transmits them to the amplification function.

3th step
Once the volumes are amplified, they are directed to the speaker (or earphone).

4th step
The electrical signals, then transformed into sound signals, are directed into the ear.

5th step
The hair cells (hair that smear the inner ear) transform the vibrations emitted by the sounds into nerve impulses. Everything is then picked up by the brain and the sounds become correctly perceptible.

Two devices, same operation

The operation of the in ear hearing aids and earloop type hearing aids is the same. For children, it may be suggested to opt for ” earloop ” aids since they tend to stay in place. They are also recommended for older people who have trouble handling smaller objects. As for those looking for a more discreet device, they could choose the in-ear for its almost invisible appearance.

However, in addition to these factors, remember to consider other elements, such as:

  1. The type of hearing loss;
  2. The space of the duct of the ear so that a prosthesis is well installed there;
  3. And personal communication and lifestyle needs (hobbies and activities).

To see more clearly, you can count on the expertise of your hearing professionals. But what better than to grasp the basis of a subject to make sure you understand it? So does your hearing health! An assessment by a hearing care professional is required to determine if the hearing aid is suitable for the patient’s needs.
