A large population wear hearing aids and they are generally very expensive. However, new breakthroughs in digital hearing aids have made buying a hearing aid a little less expensive and way more efficient.
In 2008 nearly 97% of hearing aids which clients bought were digital and that number is growing as non-digital hearing aids were no longer made by most hearing aid companies.
What accurately is a digital hearing aid and how is it different from other hearing aids? So many clients is asking this question and the answer is quite easy to explain.
Digital hearing aids make use of a technology called digital signal processing which means that the signals that create sounds enter the microphone of the equipment and are converted into binary numbers which are then processed using mathematical equations called algorithms. Each company that makes digital hearing aids uses a various algorithm to decipher the signal. This process allows extremely exact adjustment and replication of the original sound so that the individual wearing the equipment will hear crisp obvious sound quality.
Digital processing algorithms in hearing aids enable very complex manipulation of signals. A few examples are as follows:
� Separate sound into different frequency areas and amplify each area selectively, depending on the wearer’s hearing loss.
� Enable different amounts of amplification for soft, moderate, and loud sounds, so sounds are audible, but loud sounds are not uncomfortable or over amplified.
� Separate background noise from a desirable signal like speech and reduce the background noise – increasing overall listening comfort.
� Detect and eliminate whistling from occurring to enhance listening comfort.
Hearing aid technology has come a very long way in a short amount of time, nevertheless, the hearing impaired should not wonder if it will continue to refine itself through research and innovation as the on going success of digital hearing aids will enable science to further enhance the technology is the months and years to come.
The growing trend in searching for hearing devices on the web is such that companies can give digital hearing aids at highly lower fees. Hearingaidscentral.com is able to get you a digital hearing aid that would typically cost you $2000 for under $700! Something such as the Digi-Ear which gives layered noise reduction process:
Layer 1: The syllabic layer decreasing noise embedded in speech.
Layer 2: The environmental layer reducing noise when no speech is present.
Layer 3: The rapid recovery layer that gives speedy recovery of speech signals when presented and recognized.
Its design allows it to match neatly into the ear canal. The Digi-Ear DS also has a distinct rotating nozzle that will accommodate both left and right ear fitting. Rotating the nozzle is all you do. You can insert it and adapt it yourself.
This is just some things to think about regarding hearing aids, come check out the website to learn more and experience for yourself the possibilities.
