Outstanding sound quality generally unavailable in the analog version of a hearing aid can be experienced through a digital hearing aid. In addition to their excellent quality they are more durable and flexible. It has many more features because it can manipulate digital signals, which is impossible with an analog hearing aid with limited functions.
A Computer Chip Inside
There is a computer chip in side a digital hearing aid that converts analog sound wave inputs in to digital signals before passing them in to ear. This results in better quality of sound. This improved quality is because of more functions combined together to produce better quality for the user. You can also programme the digital hearing aid to function in certain types of surroundings and different frequencies in an improved way. Digital hearing aid has also features like noise and feed back reduction, better sound generation, increased speech quality, directional microphones and compression.
The first attractive feature is the ability of noise reduction enabling to decide whether the signal is speech or background noise and program the hearing aid to amplify speech sounds while reducing noise. Another feature is feed back reduction. This is a very important feature as many hearing aids have this draw back limiting the functionality and effectiveness of the device. You can adjust how much feed back is allowed in to receiver with proper programming.
A directional microphone offers improved functions to the digital hearing aid though it is available in analog hearing aids. Through the directional microphone you can hear only the sound directed at you from the front and the background sounds become faded. Compression is another notable feature in the digital hearing aid which allows low and high frequencies depending on the environment. As a result many frequencies can be set to work on a particular device.
Other specialities of the digital hearing aids are automatic gain control, protection from loud noise and use of telecoil. The quality of sound in these devices is thus increased. In spite of all these features and advantages, ensure you consult your audiologist to find the best hearing aid suitable for your needs before getting one of the instruments.
