Digital Hearing Aids

When digital hearing aids first appeared on the market in the late 1980’s, their success was very limited. Manufacturers, however, subsequently developed improved digital hearing aid technology and style, like that which went into making the Nuance digital hearing aid.

Digital hearing aids convert sound into small, discrete units based on algorithmic rules in order to process it. The simple act of turning sounds into numbers doesn’t clarify sound, though. Digital sound processing (DSP), however, does allow for the creation of improved processing features and this is where the advantage of digital hearing aids is found.

If you read information on digital hearing aids, you’ll find that they feature gain processing schemes, which provide users with better sound quality regarding sounds of interest while minimizing discomfort due to high intensity sounds. DSP technology seems to provide high quality audibility with fewer complications. Annoying low-level sounds and microphone noise can also be reduced through gain processing.

Digital hearing aids also offer digital feedback reduction (DFR), which is responsible for monitoring feedback (like that due to jaw movement and/or being in the vicinity of certain objects) and reducing or eliminating it by cancelling it out. Digital Speech Enhancement Systems (DSE), on the other had, can increase the intensity of some parts of speech; this is done based on either temporal or spectral aspects.

Digital sound processing also enhances the effectiveness of directional microphones. Digital hearing aids are better able to address the issues of microphone calibration, directional pattern shape control, automatically switching between various modalities and reduction of circuit noise.

Advanced digital hearing aids can be seen as “intelligent” hearing aids. They can distinguish between soft noises that you’d like to hear, and so amplify these, and loud noises that you’d rather not hear, and decrease their intensity. There are digital programmable hearing aids that can constantly adjust to the environment without you having to manually turn anything up or down or press any buttons. A huge benefit of these aids is the ability to create tailored programs that will address your particular hearing issues, instead of having to rely on preset or manually adjusted settings. Essentially, a digital hearing aid can give you more flexible and customized hearing improvement.

If you’re considering a digital hearing aid, do some research and consult a hearing specialist. There are a number of websites where you can read a digital hearing aid review or two, where digital hearing aids are compared and where you can find a rating for digital hearing aids. Digital hearing aids review sites can indicate the best digital hearing aids and the most affordable digital hearing aids by listing where you can find a digital hearing aid sale and discounts to purchase discount digital hearing aids. Children can also benefit from digital hearing aids. Discount aid models can be purchased for children as well; digital hearing aids for children may be changed often, so it is more convenient for you to find affordable aids for them.
