In 1898, Miller Reese Hutchison created the first electric hearing aid. In 1913, the first commercially manufactured hearing aids were released. The first electric hearing aid was invented in 1898 by Miller Reese Hutchison. He used an electric current to amplify the sounds.
The design itself was a carbon transmitter, which allowed the device to be portable. However, the first mass-produced hearing aids were too cumbersome and not as portable. Users would then hold a receiver connected to this box up to their ear so they could hear well. The creation of high-speed digital matrix processors used in mini-computers opened the door to advancements in all-digital hearing aids.
Despite the improvement, they were still heavy, bulky and eye-catching and amplified all the sound, not just the sounds the user wanted to hear. With a funnel-shaped design, ear trumpets were man's first attempt to invent a device to treat hearing loss. Now, virtually all commercial hearing aids are fully digital and their digital signal processing capacity has increased significantly. The technology behind this used an electric current to amplify weak signals, allowing the user to hear things louder.
It became famous as “the best electrical aid for the semi-deaf so far conceived and more than once it was called a “miracle”. In 1870, Thomas Edison, who also experienced hearing loss, saw considerable room for improvement and invented a carbon transmitter for telephones. Hearing aid technology has obviously made great strides from ear trumpet to purely digital technology. Long-wearing hearing aids, which can stay in the user's ear canals for several weeks, have been available for several years.
One of the first manufacturers of electronically amplified hearing aids was the company Siemens in 1913.One problem associated with them is that they amplified all the sounds rather than specific sounds that the user wanted to hear. In 1898, Miller Reese Hutchison of Alabama used the technology to create the first electric hearing aid. All of these things influenced the development of hearing aids that were small enough to be practical and usable. However, this research on digital processing was important in learning how to develop sounds for people with hearing impairments.
