It is impossible to determine exactly when or who invented the hearing aid because electric hearing aids have been around for over a century and even before that, people used horns to transmit sound into the ears and block out hearing loss.
Today, hearing aids have become digital. Advances in technology have led to more innovations to overcome the consequences of hearing loss. Your hearing aid specialist will be able to inform you about the benefits of modern hearing aids. For now, here's an overview of the history of hearing aids.
When were hearing aids invented?
The first hearing aids were made using animal horns. They are also known as ear trumpets and date back to at least the 17th century. Their main purpose is to treat people with partial hearing loss. These hearing aids are installed around the room and in furniture to help amplify sound. This hearing device is eventually adapted into a tube to fit into the ear. However, many people consider the invention of the first hearing aid to refer to the invention of the electric hearing aid.
Electric hearing aids were developed in the late 19th century. Human exploitation of electricity initiated many new inventions. The telephone was a major invention that influenced the invention of hearing aids. Telephone and microphone technology have inspired developments in communications and audiology. The ability to control the volume, frequency, and distortion of sound has been used to create electric hearing aids.
Who invented the first hearing aid?
The first electric hearing aid was invented in 1898 by Miller Reese Hutchison. He used electric current to amplify sound. The design itself is a Carbon microphone, allowing the device to be portable. However, the first mass-produced hearing aids were too bulky and unportable.
Thomas Edison, who suffered from hearing loss, also invented a carbon emitter that was later used as a precursor to carbon hearing aids. Another hearing aid expert and inventor at the time, Louis Weber, created the Esha-Phonopher hearing aid. This electric hearing aid, invented in 1911, inspired the founding of the hearing aid manufacturing company Siemens.
The next development in this technology was the vacuum tube hearing aid, produced around 1920. Naval engineer Earl Hanson patented this design. Speech will be converted into an electrical signal and then amplified.
Further advances in hearing technology occurred as a result of military investment during World War II. This led to the invention of the transistor hearing aid developed by Bell Laboratories in 1948. It was eventually miniaturized and today's portable hearing aids were born.
How have hearing aids evolved?
Hearing aids have been improved by digital technology since around the 1960s. In 1970, the invention of the microprocessor allowed digital hearing aids to become smaller and miniaturization was completed. good. A hybrid hearing aid, including both digital and analog, was also created in the 1970s.
The first commercially successful digital hearing aid was created by Widex in 1996. Silicon became the main material that made hearing aids more convenient. By the 2000s, hearing aids became fully adjustable, and digital hearing aids are by far the most popular. However, manufacturers are continuing to focus on adjusting the machine's design.
Nowadays, digital hearing aids are also adjustable. This means being able to control the sound yourself without the need for external input (such as a physical volume control). The hearing aid can also be adjusted to your requirements and connected to other devices using Bluetooth.
What is the future of hearing aids?
Hearing aids can now be adapted to stream phone calls, music, and podcasts from iOS or Android devices. A number of applications are being developed to improve digital hearing aids by taking advantage of the potential sound processing power in smartphones. Hearing aids themselves are becoming smart devices and We can expect more in the future.
There are also continuing developments in the size, shape, and batteries of hearing aids. They are being improved to be more convenient and more durable. Hearing aids are also increasingly customized to fit individual needs. A hearing aid specialist will be able to advise you on the type of hearing aid that is right for you.
