9 Points Advantages of Digital hearing aid(DHA):

According to researches DHA have a number of significant advantages (compared to analogue hearing aids):

 1.Digital signal processing helps to reduce noise and distinguish the speech signal from the overall spectrum of sounds which facilitates speech perception.

 2.Reducing of background noise level increases the user’s comfort (especially in noisy environments, e.g. on the street).

 3.Setting flexibility provides selective amplification of certain frequencies (in accordance with the personal characteristics of the hearing impaired).

 4.Effective acoustic feedback reduction.

 5.Possibility to use directional microphones, which greatly facilitates the perception of sound in certain environments, e.g., when talking face to face, or listening to the remote lecturer.

 6.Extended frequency range (the ability to hear a large range of sounds).

7.“Self-learning" adaptive adjustment which facilitates usage of the device for a number of users.

8.Possibility of connecting devices (phones, smartphones, etc..).

9. In general, the maximum purification of the sound transmitted to user.

These advantages of DHA were confirmed by a number of studies, relating to the comparative analysis of digital hearing aids of second and first generations and analog hearing aids.
