Anyone who is personally affected by hearing loss—or has family members struggling with this issue—is interested in the topic of how hearing aids can help with hearing loss. Whether it’s young children, older children, or adults, anyone who has trouble hearing clearly is glad to have access to technical assistance. Today’s modern devices are a far cry from the technology of the first models. Research has made significant strides in this area, and thanks to these advances, a variety of hearing aid models are available today. Their function and use depend on the condition—or rather, the severity—of the hearing loss. The technical features of the hearing aid are just as crucial to its success as its placement on the ear. Generally, the following types of hearing aids are available:
- Behind-the-ear hearing aids are also available in very small sizes and can help with almost all types of hearing loss
- So-called in-the-ear hearing aids fit perfectly into the ear canal, conforming to the ear's anatomical shape. For mild to moderate hearing loss, they are chosen by approximately 10% of those affected.
- In addition to these designs, there are analog hearing aids, digitally programmable analog hearing aids, and fully digital hearing aids, which are increasingly replacing analog hearing aids.
There are also special implants, but these are inserted during surgery. They are typically used in cases of near-total or complete deafness. The other two types are fitted for babies, children, and adults; this work is performed by a hearing aid specialist, and it can also be arranged online at www.audibene.de.
How do hearing aids work?
Even though a hearing aid cannot fully replace the function of an ear, they have become an important and irreplaceable aid. They are able to at least compensate for existing hearing loss and allow the person affected to lead a relatively normal life. Just 10 years ago, it was not possible to achieve the results we see today, which shows how much progress has been made in this field in recent years. A hearing aid works on the principle of a microphone, an amplifier, and a receiver. The microphone converts sound waves—that is, sounds—and the receiver amplifies and reproduces them. Whereas large devices were once necessary, miniature models are now the norm.
From the Ear Trumpet to High-Tech Devices: How Hearing Aids Help People with Hearing Loss
Beethoven always kept a hearing tube nearby; without it, he could hardly have communicated—it’s a miracle that he still managed to compose his classical music. As early as the 17th century, hearing aids began to be mass-produced, and their rapid development took off from there. Carbon microphone devices and tube amplifiers were a sensation back then; today, it’s hard to imagine having those things in one’s ears. The invention of semiconductor technology ultimately sparked the decisive leap forward in hearing aids; subsequent devices, thanks to continuous development, operate using microchips and sophisticated algorithms and feature over a million transistor functions.
