Why does music from a CD sound more crisp, clear, and distortion-free than music from a record or tape? The answer, at least in part, is the difference between analog and digital sound processing.

There are many types of hearing aids, the most advanced and popular is digital one. Digital hearing aids have one or more microchip processors inside them that convert analog sound waves into the zeros and ones of computer language. Sound in this format can be processed more quickly and efficiently, in fact, incoming sounds are sampled at a rate of million times per second. Digital technology analyzes these sound levels and frequencies, manipulating them to provide a more efficient match to your hearing profile.

For example, a person with a hearing loss may have trouble hearing soft sounds, but when some sounds are amplified event a small amount, they become uncomfortably loud. Digital hearing aids stratify incoming sounds, detect those that need amplification from those that don’t, and process the sounds accordingly. Patients should ask their audiologist for helping them define level of hearing loss through test results and their need. Unlikely common hearing aids, digital ones can analyze noise, prevent too loud amplification, automatically reject feedback when using electronic devices such as mobile phone… In addition, digital hearing aids can help patients get the natural, clear and actual sound.
