To find out more about how Widex hearing aids
get their true-to-life sound, it’s important to take a step back to where the whole process begins. Developing a new hearing aid
can often take five or more years
and it all starts with the experiences and wishes of existing hearing aid users which are gathered and transformed into ideas for new products at the engineers´ drawing board.
For example, Widex got the idea to develop its audibility extender after realizing that some hearing aid users were having difficulty hearing upper frequency sounds
. The extender moves these sounds to a lower frequency region where it is easier to hear them.
After the brainstorming phase, ideas are scheduled for development. That’s where the sound library comes in. As features like the audibility extender are created, rounds of testing begin. Sounds like birdsong, bells, and timers
are used to test upper frequency sounds that the audibility extender helps hearing aid users to hear.
“It gives us a frame of reference for the hearing aid feature we are developing,” says Jens. “We listen to how this feature helps the sound in real-life situations and tweak it to make it sound as natural as possible.”
The final test
After a feature is developed, the technology is added to the physical hearing aid. But that’s not where the story ends. Hearing aids
are then tested again by specially-trained sound expert
who make sure that the technology is working correctly.Hearing aids
are then produced and shipped to your hearing professional
, who will program them to fit your particular hearing loss.
