Technological Advances in Digital Sound Processing Hearing Aids


Before the technological advancements we have today, if you needed to have a hearing aid, you would have been given one with analog amplification, which simply turns the volume up and makes every sound louder.

These kinds of hearing aids benefited everyone who was suffering from ‘flat hearing loss’, which is when hearing has deteriorated completely across the board.  Unfortunately, most people do not experience a flat hearing loss.

Most people with hearing problems find that some sounds are heard much easier than others and that only some types of sounds are lost altogether.  If you simply turn the volume up for all sounds, then the sounds that you have difficulty hearing will not be made clearer; if anything, they will be more distorted due to the fact that you are also turning the volume up for sounds you can already hear perfectly well.

Fortunately, twenty years ago, Digital Sound Processing (DSP) hearing aids came into existence.  Thanks to this advancement, hearing experts are now able to customize hearing aids specifically for the person wearing them.  This ensures that sounds the person has an issue with are targeted while the ones that aren’t a problem are ignored.  As hearing changes over the years, the hearing aids can be adjusted as needed.

Receiving a hearing device can be just as frustrating as when you lose your hearing in the first place.  While the latter usually happens gradually over time, putting on a hearing device for the first time can immediately expose the wearer to all sorts of subtle sounds that he or she might have forgotten existed.  Imagine a sensory overload caused by a refrigerator humming or a car’s engine!

One of the most difficult things associated with hearing loss is the ability to understand speech and communicate.  Once a DSP hearing aid is fitted, be aware that it won’t be an instant cure.  The wearer will be confronted with a barrage of noise and will have to relearn how to filter out irrelevant sounds and filter in the ones he or she needs.  Be patient and practice the art of conversation with your loved one.  If he or she has in-home care in Dallas, ask his or her Caregiver to help with this, too.
