The inner life of hearing aids
Most hearing aids are designed with the same idea in mind: to capture sound and process it so that the wearer can hear properly. However, this still leaves many questions. What do hearing aids look like inside? How do hearing aids work?
To help people better understand the inner life of hearing aids, Signia has created a video walkthrough and text guide that can serve as the perfect explanation for potential customers.
Hearing Aids: An Inside Look
Beneath the surface, hearing aids are made up of several electronic parts. One or two microphones capture sound and translate it into signals. These signals are sent to the processor, which is where the bulk of the work is done. There, user needs and software determine how the noises will sound. Factors like volume, contrast, and even OVP (Own Voice Processing) come into play here.
The processing happens in the blink of an eye, and the coded sound is then sent through the electrical cords to the receiver, where it is transformed and transmitted to the wearer. This allows people with hearing loss to hear clearly, no matter what they’re listening to. While different hearing aids might contain different processors and software, the general idea is the same.
Why Do Hearing Aids Look Like They Do?
Hearing aids require a sleek, streamlined design in order to work properly. They need to fit all the necessary hardware into a compact shape, and then they need to be fitted. The shape of the hearing aid contributes greatly to how appealing it is to potential buyers. While you could make hearing aids in square shapes, they wouldn’t fit comfortably on people’s bodies.
Hearing aid design relies on creating a comfortable, organic device that is easily worn and hidden behind the ear. Many hard of hearing people do not want to wear large, clunky devices on their heads. This makes them feel self-conscious and decreases their likelihood of trying hearing aids in the first place. For these reasons, developers created a more aesthetic design that still contained all the necessary technology.
The bean-shape of a behind-the-ear hearing aid lets it sit over the wearer’s ear, where it can be hidden and camouflaged. Once fitted, it can become as easily worn as a pair of glasses. Different colours allow it to be customised to the wearer. Flesh tones can hide the device further, while other colours make it pleasing to the eye.
Where Do The Batteries Go?
Hearing aids contain more than just microphones and receivers. Batteries must be included to keep things running, and these are usually kept in a place where they’re easily accessed. In hearing aids powered by zinc-air batteries or rechargeable cells, the power source is kept underneath a removable panel. This allows for easy replacement once the battery need to be changed. Latest Signia hearing aids are energised by high-capacity Li-ion power cells to charge them up while the wearer sleeps.
With innovation and improvement, hearing aids are becoming smaller and smarter. While all hearing aids share the same general concept, they’re constantly evolving to become better
