Types of hearing aids

All hearing aids work according to the same principle: they pick up ambient noise, the sound is converted into electrical impulses and then forwarded, in a modulated form, to the ear. However, depending on the severity of the hearing loss and personal requirements, hearing aids can differ considerably. Not just in terms of shape and size, but also in terms of their properties and functions. This diversity ensures a solution that meets your desires and expectations.

This variety ensures that the hearing aid can be adapted to your personal preferences and expectations, so that nothing stands in the way of your hearing.Below you will find a brief summary of the different types of hearing aid, based on the features they offer.

What are the differences between digital and analog hearing aids?

Hearing aids can be either analog or digital. Most new hearing aids are digital. The only difference between analog and digital devices results from the way in which they process signals.Analog hearing aidspick up signals from the surroundings. The signals are then reproduced and amplified by a loudspeaker. These devices are unable to filter out or reduce noise.Digital hearing aidsconvert sound into electronic information. Only major signals are amplified and transmitted. Loud ambient sounds are reduced. This means that the wearer can hear better even in noisy environments. These devices can be adapted to individual needs and are smaller than analog models. Digital hearing aids also deliver improved sound quality and enhance speech comprehension.Both analog and digital hearing aids are available in two main types: behind-in-the ear and in-the-ear.

What are behind-the-ear (BTE) models?

These hearing aids are worn behind the ear, just above the concha. The small, clear tube transmits sound directly into the eardrum and is also used to keep the hearing aid in place. BTE models are available in a variety of styles, sizes and colours. They are also sweat, dust and water resistant.

Advantages of BTE models:

Space for larger and more powerful batteries. Rechargable options available.
Larger program selection buttons that are easier to operate
Variety of colour options
Connection to mobile phones, TV and stereo’s via Bluetooth

Disadvantages of BTE models

Less suitable for people who wear eyeglasses
Prevents use of the natural functions of the concha
Less discreet

Structure of a BTE hearing aid

All hearing aids feature the same key components. For example, a behind-the-ear hearing aid has the following functions:

Microphone – Picks up sounds and converts them into electrical signals
Amplifier – Increases the volume of the microphone and filters out irrelevant sounds
Loudspeaker – Converts electrical signals into acoustic signals
Speech processor – Adjusts signals to the wearer's individual hearing needs
Volume regulator – Lets the wearer control the volume
Ear hook – Connects the hearing aid and the sound tube
Audio input – Picks up signals from other external devices
Battery powered and Rechargable options available.

Other behind-the-ear (BTE) hearing aids

Receiver-in-canal (RIC) and Micro-behind-the-ear modelsRIC and Micro-behind-the-ear hearing aids are smaller BTE options. They are equipped with receivers that transmit sound directly in the ear canal. They are worn comfortably behind the ear, come in a variety of colours and have Bluetooth capabilities.

What are in-the-ear (ITE) models?

ITE Models are a discreet option that sit inside the ear itself. The device's electronics are encased inside an acrylic shell that is inserted into the ear like an earplug, sending sound directly into the ear canal. Some ITE devices have an antenna-like plastic tab for easy removal.

In-the-ear hearing aids are self-contained units. Volume can be adjusted and programs can be selected by remote control. Many models can be connected wirelessly to mobile phones and TVs.

Advantages of ITE devices

Extremely discreet and barely visible from the outside
Invisible options available
Easy to insert
Bluetooth capability

Disadvantages of ITE devices

Only suitable for those with mild or moderate hearing loss
Use depends on the size of the ear canal
The battery needs to be changed frequently
An audio connection, in the form of an audio shoe, is not possible due to lack of space, and a T-loop can only be attached to concha models
