Digital Hearing Aids have more Features and Better Sound Quality
If you want to experience outstanding sound quality that is normally not available in the analog version of a hearing aid, then opt for a digital hearing aid. Besides the excellent sound quality, these types of hearing aids will also be more durable and more flexible. The digital hearing aid has many more features because it is better able to manipulate digital signals, which is not possible if you use an analog hearing aid with limited functionality.
A Computer Chip Inside
A digital hearing aid has a computer chip inside which can convert analog sound wave inputs into digital signals before being passed into the ear. This sampling means that you get a better quality of sound, and using a digital hearing aid will result in improved quality because there are more functions that can be combined together to output better sound quality to the user. It is also possible to program the digital hearing aid to function in certain types of environments and different frequency bands, making it possible to process more frequencies in an improved manner. Also, the digital hearing aid has many more features including noise and feedback reduction, better generation of sound, enhanced speech quality and directional microphones and compression.
The first feature that attracts attention is the noise reduction ability, which makes it possible to determine whether the signal is speech or background noise, and program the hearing aid to amplify the speech sounds while reducing noise. Another feature of the digital hearing aid that needs to be considered is that of feedback reduction. This is an important feature, because many hearing aids suffer from this annoying drawback that can greatly limit functionality and effectiveness of a device. With proper programming, it is possible to adjust how much feedback is allowed into the receiver.
A directional microphone, although also available in analog hearing aids, is particularly useful in the digital hearing aid because it provides improved functionality. This makes it possible to turn on the directional microphone and listen only to sounds that are directed at you from in front, while any background sounds become faded. Another notable feature of the digital hearing aid is that of compression, which enables a device to pass low or high frequencies depending on the environment. This means that many frequencies can be set to work on a particular device.
In addition, it is also common to find other features on a digital hearing aid such as automatic gain control, protection from loud sounds and use of a telecoil. Together, these features improve the quality of sound in these devices. Nevertheless, before buying one of these instruments, discuss your options with your audiologist to find out the best hearing aid suited to your particular needs.
