Digital Hearing Aids - The Future Is Hearing Now
Digital hearing aids are no longer a thing of science fiction. With the remarkable breakthroughs in hearing aid technology combined with advances in digital science things once thought to be products of the imagination of science fiction writers are now reality. Digital hearing aids are not just your ordinary hearing instrument used to listen to the world around you. Instead, these revolutionary devices can make living with a hearing impairment seem as if it never existed at all.
One of the biggest benefits to digital hearing aids is that each digital hearing instrument can be specifically tailored to the patient’s precise level of hearing impairment. This action is performed with a new technology, called digital signal processing (DSP). Digital hearing aids with DSP take sound from the outside environment and convert it into a series of numbers processed by a computer chip inside the hearing aid. The numbers are then re-converted back into the same sound waves originally taken in and are directed through the hearing aid interpreted by the listener.
The ability to re-convert sound waves numerically allows digital hearing aids to amplify speech and quiet loud and unwanted background noise. Because each individual has different hearing needs, and because a hearing impairment varies from patient to patient, audiologists are able to customize each digital hearing device according to what the listener interprets for different environments. This means that a patient can have their digital hearing aid programmed to pick up soft sounds, if that is where their hearing impairment lies, while a patient who can hear soft sounds will have their device programmed to pick up louder noises.
Digital hearing aids also have the capability of -adaptive directionality.- This hearing aid technology allows the hearing aid to address sounds coming from various directions in a different manner. Someone wearing a digital hearing device with this type of technology can comfortably listen to someone speaking in front of him or her without having noises from behind interrupt the sound waves. This, in turn, maximizes speech quality in noisy places like restaurants, shopping malls, or grocery stores.
Digital hearing aids have also eliminated the problem of -whistling- or -squealing- by infiltrating adaptive feedback management into this type of hearing instrument. DSP, which helps tailor sounds for the individual, also allows for the microphone inside the hearing aid to minimize amplified sounds too. In older analog models, the sound wave returns to the microphone re-amplified, causing a -whistling- to occur.
Digital hearing aids have made many technological advances in the last few decades. There is room for improvement, though. As researchers and doctors continue to study the DSP technology, they will likely find ways to make them more readily available and more effective for a large number of people. Fueled by the fact that these digital hearing instruments are helping to make life easier for many people, researchers are optimistic for the advances that they can make in the near future.
