Digital hearing aids contain computer chips that convert the continuous electronic signal into numeric coded signals. In this form, the digital hearing aid can perform complex processing of the sound, such as reducing the intensity of loud background noise, at an extremely fast rate and with a high degree of precision. This type of hearing aid, programmed via a computer, offers the greatest flexibility in its ability to match the hearing aid response to the hearing loss. Similar to the digital technology used in CD players, cameras and cell phones, digital hearing aids offer advanced sound quality and sophisticated features.

Programmable hearing aids must be connected to a computer in order for your hearing healthcare professional to make adjustments. These hearing aids offer more flexibility and can provide more features.
