There s no shortage of hearing aid devices and assistive hearing devices for the home and office, says University of Calgary auditory researcher Dr., David Brown. You dislocate one of the bones of the ear and you connect the device to it. The device directly connects to the bone, like a direct drive.
All hearing aids function the same, however.
There are a dozen or so major, multi-national manufacturers of hearing aids, as well as numerous independent makers. Technological developments began primarily after the Second World War, when so many soldiers returned to their homelands with damaged-hearing from the excruciating noise of battle. An audiologist will take an ear mold, and impression of the person s ear, that is used to make the device fit properly in the ear. Disposable hearing aids are also about to be released on the market, Brown said. They last about 40 days, for the life of their battery, and are designed for people who aren t sure they want a hearing aid but want to find out how they feel before going to the expense of ordering and fitting a permanent one.
