Hearing aid technology continues to advance at a pace second only to the technology that fuels modern space exploration. In thirty years, hearing aid circuits improved from making 3 judgments per second to 300 million judgments per second! Processing speed enables the audiologist to simultaneously raise the volume for speech and lower the volume for noise, all with no echo. Faster processors make circuit noise inaudible, amplify the telephone, and selectively reduce sound from the sides and behind you. With all the different styles and features of modern hearing aids, how do you select the device that will best accommodate your particular degree of hearing loss? Below are links to important information you'll need before you invest in hearing instruments.
