Follow on Google News | Phoenix Hearing Aid Options for People in NeedBy: Metro Hearing A hearing aid, simply put, is a sound-amplifying device. Analog hearing devices amplify sound by making the sound waves larger. They use transistors in a circuit to modify and amplify sound, and any changes to the sound are simply made with a volume control. Some analog aids are actually programmable – digitally programmable, meaning their sound response can be changed internally by a hearing aid professional. This doesn’t mean the device is a digital hearing aid, though. It’s an analog device with digital programming capabilities. True digital hearing aids are known as DSP devices, or Digital Signal Processors. With this technology, a computer chip converts incoming sound into digital code, analyzing and adjusting the sound according to your personal hearing loss, needs, and surrounding noise levels. From there the signals are converted back into sound waves and delivered to your ears. Many people prefer these because of their outside noise reduction features. The process of choosing the best hearing aid can be daunting, so the more hearing aid information you ask of your audiologist and hearing aid fitter, the more empowered you’ll be to make the right decision for you.
