Making the Right Choice when it Comes to Hearing Aids
A large population wear hearing aids and they are generally very expensive. However, new developments 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 improving as most hearing aid companies no longer make non-digital hearing aids.
What exactly is a digital hearing aid and how does it vary from other hearing aids? So many consumers is asking this question and it is easy to explain the answer.
Digital hearing aids use a technology called digital signal processing which means that the signals that produce 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 makes use of a various algorithm to decipher the signal. This process allows extremely precise manipulation and replication of the original sound so that the person wearing the equipment will hear crisp clear sound quality.
Digital processing algorithms in hearing aids enable very complicated manipulation of signals. A few examples are as follows:
� Separate sound into various frequency areas and amplify each region selectively, depending on the wearer’s hearing loss.
� Enable various amounts of amplification for soft, moderate, and loud sounds, so sounds are audible, however, loud sounds are not uncomfortable or over amplified.
� Separate background noise from a desirable signal including speech and decrease the background noise – improving overall listening comfort.
� Identify and eliminate whistling from occurring to enhance listening comfort.
Hearing aid technology has come a very long way in a short amount of time, yet, 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 improve the technology is the months and years to come.
The growing tendency in searching for hearing equipments on the web is such that companies can give digital hearing aids at extremely lower fees. Hearingaidscentral.com is able to get you a digital hearing aid that would generally cost you $2000 for below $700! Something such as the Digi-Ear which gives layered noise decline process:
Layer 1: The syllabic layer that reduces noise embedded in speech.
Layer 2: The environmental layer that reduces noise once no speech is present.
Layer 3: The rapid recovery layer that gives fast 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. Rotating the nozzle is all you do. You are able to insert it and adapt it yourself.
