Hearing aids are the prescribed treatment for permanent hearing loss. Untreated hearing loss has been empirically shown to negatively affect many areas of life, including: social, emotional, communication, relationships, and financial earning. Properly fit and programmed hearing devices have been shown to drastically reduce the negative effects of hearing loss. NOTE: The state of NC requires a high school diploma and no criminal background to sell hearing aids as a hearing instrument specialist, and the quality of devices and services varies greatly by provider. A board certified Doctor of Audiology is the highest standard available and verifiable.
