DIGITAL technology is the most sophisticated hearing aid technology. Digital technology gives the audiologist maximum control over sound quality and sound processing characteristics. A variety of levels of digital technology, styles, and manufacturers are available based upon the patients’ hearing loss, as well as their financial means and desires. Hearing instruments are much more discrete than in the past. There are options with blue tooth compatibility which allow patients’ hearing instruments to connect with cell phones, landline phones, personal microphones, and televisions resulting in a whole new world of sound and hearing.
