Advantages of Digital Hearing Aids
Digital hearing instruments are able to create advanced signal processing schemes that non-digital instruments simply aren't capable of. Additionally, digital instruments can perform multiple sound processing and management tasks efficiently and simultaneously!
For example, digital technology gives us the capability of determining which signals are most speech-like and which sounds are most likely noise. Once a hearing aid determines differences related to speech and noise characteristics, we can program the aid to essentially amplify the speech-like noises, while trying to reduce the background noises. Of course, when this is accomplished, a more comfortable listening experience is appreciated very quickly.
Another example of digital capability deals with the control and management of feedback (the whistling noise that all hearing aids make in certain situations). Digital technology allows the instrument to determine when feedback is going to occur and then virtually cancels it out so that it isn't audible or annoying!
It is important to understand that not all digital hearing aids provide the same benefits. Simply making it ''digital'' doesn't make it better. However, making it digital allows the manufacturer to offer a quality, variety and range of features which simply is not possible in non-digital instruments.
The best way to determine if a digital instrument would benefit you is to speak with your hearing healthcare professional about issues specific to your hearing loss and your hearing aids. Your hearing healthcare professional can help determine if the advanced capabilities of digital hearing instruments can provide greater assistance to you.
