Making the Right Choice when it Comes to Hearing Aids
Hearing aids are worn by a large population and are generally very expensive. However, new breakthroughs in digital hearing aids have made buying a hearing aid a little less costly and way more efficient.
In 2008 about 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 exactly is a digital hearing aid and how does it vary from other hearing aids? This question is being asked by so many consumers and the answer is rather simple to explain.
Digital hearing aids utilize a technology called digital signal processing which means that the signals that make sounds enter the microphone of the device and are converted into binary numbers which are then processed using mathematical equations named algorithms. Each company that produces digital hearing aids uses a various algorithm to decipher the signal. This process allows extremely correct adjustment and replication of the original sound so that the individual wearing the device will hear crisp clear 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 regions and amplify each area selectively, depending on the wearer’s hearing loss.
� Enable various amounts of amplification for soft, moderate, and loud sounds, so sounds are audible, on the other hand, loud sounds are not uncomfortable or over amplified.
� Separate background noise from a desirable signal such as speech and decrease the background noise – increasing total listening comfort.
� Detect and eliminate whistling from occurring to strengthen listening comfort.
Hearing aid technology has come a very long way in a short amount of time, yet, the hearing impaired should not worry about if it will continue to refine itself through research and innovation as the on going success of digital hearing aids will allow science to further increase the technology is the months and years to come.
The growing tendency in searching for hearing equipments on the internet is such that companies can provide digital hearing aids at extremely lower costs. Hearingaidscentral.com can give you a digital hearing aid that would usually cost you $2000 for under $700! Something such as the Digi-Ear which offers layered noise decrease process:
Layer 1: The syllabic layer that decreases noise embedded in speech.
Layer 2: The environmental layer that reduces noise once no speech is present.
Layer 3: The fast recovery layer giving quick recovery of speech signals when presented and recognized.
Its shape allows it to match neatly into the ear canal. The Digi-Ear DS also has a special rotating nozzle that will accommodate both left and right ear fitting. All you do is rotate the nozzle. You are able to insert it and adjust it yourself.
