As many as a third of Americans experience hearing loss between ages 65 and 74. This frustrating – and sometimes undetected condition means they can’t properly hear what people are saying. And this in turn leads to feelings of social isolation. We wrote this post to explain how digital hearing aids work. However, we first need to detour into how we hear when everything is working properly.
How We Hear. The Original Manufacturer’s Design
Sound arrives in our ears through a narrow canal leading to our ear drums. The sound waves cause the drums to vibrate. Next, these vibrations reach three tiny little bones on the far side of the drum. Then these bones boost the vibrations and forward them to a snail-shaped structure containing fluid.
Finally, a wave ripples through the fluid, and creates electronic signals as it brushes against microscopic hair-like projections. Our brains process these signals into sounds we ‘hear’ in our minds. This is a very simple explanation of the basic principles of hearing. This video explains the details.

Things That May Cause Our Hearing Loss as We Age
Our bodily functions gradually deteriorate over time and that applies to our hearing too. According to National Institutes on Deafness and Other Communication Disorders (NIDCD) there are various factors causing this. These triggers include:
- Gradual changes in our middle or inner ears as we grow older
- Variations along the nerve pathways from our ears to our brains
Certain medications can also affect our hearing. Please consult your medical professional ordering digital hearing aids from us.
How Digital Hearing Aids Work to Improve Our Hearing
Modern digital hearing aids are actually powerful microcomputers tucked into tiny spaces. They have settings specialists can program to perfectly adapt to a user’s needs, based on a hearing test.
If you’d like to know how digital hearing aids work from a technical perspective these are their basic functions:
- A microphone receives sound from the environment and sends it to a processor
- The processor magnifies the sound and changes it from an audio to an electronic signal
- A loudspeaker releases the sounds into the user’s ear where nature processes them as before
However, it’s even more important to know what a digital hearing aid could do for a hearing-impaired person, perhaps even you if you are struggling to make sense of the blurred noises around you.
We never promise to return your hearing to the original standard at Blue Angels Hearing. Nobody can do that. However, our digital aids could improve your hearing to the extent you can hear what people are saying again, and enjoy chatting at dinner parties like you did when you were young.
