The History of hearing aids:(Edit by Adsound)
The first hearing aids were ear trumpets, and were created in the 17th century. Some of the first hearing aids were external hearing aids. External hearing aids directed sounds in front of the ear and blocked all other noises. The apparatus would fit behind or in the ear.
The movement toward modern hearing aids began with the creation of the telephone, and the first electric hearing aid, the "akouphone," was created about 1895 by Miller Reese Hutchison. By the late 20th century, digital hearing aids were commercially available.
The invention of the carbon microphone, transmitters, digital signal processing chip or DSP, and the development of computertechnology helped transform the hearing aid to its present form.
