History of Hearing Aids – A Brief SummaryHearing loss in one form or another has affected many people over manyyears. People suffered from hearing loss due to genetics, old age, damageor disease. There were a number of devices developed to help to overcomethese impairments. Hearing aids have been the most successful andeffective device to address this problem so we’ll discuss a brief history ofhearing aids.The first hearing aids were developed about two hundred years ago. Theycame about in the form of ear trumpets which were large horn shapeddevices which could direct sounds in to the ear of someone suffering fromhearing loss. It helped to amplify the sounds and made it easier for thatperson to follow conversations or discern different sounds.Of course this device wasn’t very portable or easy to carry around. But atleast it provided some relief for those who suffered from moderate to severehearing loss.The development of the telephone in the late 1800’s paved the way foramplification of sound through electrical means. The telephone wasessentially a device which could amplify sound through a carbon microphoneand a power source from a battery.In the early 1920’s, vacuum tube technology allowed hearing aid devices tofunction fairly well. It could amplify the sound in an efficient manner. Butthese devices were still quite large and cumbersome to be practical on a dayto day basis.Fortunately the development of the transistor played a pivotal role inminiaturizing hearing aids. They enabled these devices to worn comfortablyaround the ear and provided a much better solution to hearing loss.Beginning in the 1950’s hearing aids featured transistor technology andcontinuous refinements from that point resulted in ever smaller and moreeffective products.
The advent of digital technology in the 1990’s brought about even morecompact designs as well as the ability to provide a much better listeningexperience. Feedback and extraneous noise could be more effectivelyfiltered out. A notable advance was the ability to allow users to discernconversation in noisy environments; this was a significant challenge forearlier devices.The technology and features of hearing aids continues to evolve andimprove, thereby bringing about greater effectiveness and improved qualityof life for its users.For More Information on History of Hearing Aids, Call Atlanta Hearing Associates At: (770) 574-4819 Or Visit Us At: http://hearing-aids-atlanta-ga.com
