Hearing loss is a very devastating ailment that affects millions of people all around the world. However, it can be treated via medicine or even using a hearing aid. That is why it is so important that people understand all of the costs and research that must occur before any of these devices can even be fit for a person. For this reason, it is important that we look at the very long and storied past of the hearing aid so that we can pinpoint a few devices that were integral in making them what they are today.
Carbon Form Hearing Aids
One of types of hearing aid that was better as a model for the future of hearing devices than a functional piece of equipment. This device came with a microphone that would be able to amplify the sound that was directed towards it, causing the carbon inside to slam against a waiting magnetic sheet. The loud sounds that were created by this were able to replicate just about all sounds, but not too well. The sounds were loud enough that they could be interpreted, but not without great effort. That is why they were not very popular, along with other reasons. The device was far too heavy to be taken along and required a very quiet and stable environment to work in.
Vacuum Tube Hearing Aids
Vacuum tubes were a form of hearing aid that was made available throughout the mid 20th century. These hearing aids were able to take in sound from around them, run them through a vacuum tube, and then have them come out of the receiver on the far end at a much louder volume than before. This led to people being able to hear better and also have the product on their person at all times because it was a very lightweight product. This was not only a good way to get better hearing, but it was also a good way to convince investors to put more money towards hearing aids.
Another one of the first types of hearing aids was one of the most basic pieces of technology ever created. It was a long tube that was hollow. On one side was a large, bell shaped opening that could gather sound and direct it through the tube to the other end. The other side was conical and could fit into the ear of the individual. They would be able to hear the sound in a more direct way, but the fact of the matter is that it could not be made louder. This inspired people from all over the world to begin using technology in future hearing impairment treatment devices.
