Affordable Hearing Aids
In 2008 Songbird Hearing wanted to figure out what hearing aid to develop next. Our research revealed needs that were not being met by the traditional hearing aids on the market at that time.
This work reflects the upfront user research, and subsequent user experience/human factors evaluation of a prototype of the first over-the-counter, disposable hearing aid to be sold at a price point for less that $100.
Methods
In order to develop a strategy and understand user needs we interviewed doctors and people suffering mild to medium hearing loss. We also observed patients getting their hearing checked as well as having hearing aids sized and fitted.
Resistance to Seeking a Solution
There is a great deal of reluctance to seeking help in people suffering low to medium hearing loss:
-
It can be challenging for some families to convince a patient that they have a hearing problem and to see a specialist. Some continue to deny a problem despite the results of a hearing test.
-
Cost is also a deterrent. Hearing aid are expensive and many patients make the investment only to abandon the technology because of discomfort, embarrassment or frustration.
Concept Development
Our research led us to the objective of designing the first over-the-counter disposable hearing aid that could be sold for less that $100.
To accomplish this price point, one design had to be able to fit both the left and right ear, regardless of the size and shape.
Obstacles
No two ears are alike
​
Designing a “one size fits all” hearing aid was a challenge because both the exterior and interior of each ear is unique; there is no correlation to any other measurable and documented anthropometirics. The device needed to be fully adjustable.
Product Refinement
​Since the target audience was largely elderly, attention was paid to factors related to usability and aging, such as reduced dexterity, tactile sensation and impaired vision.
​
Removing a doctor’s involvement simplified the process for the consumer but also eliminated the opportunity for face-to-face instruction to ensure proper fit and use.
User Testing
Our study evaluated consumer acceptance of the lead design elements, and the clarity of the Instructions For Use (IFU).
We investigated the fit, functionality and ergonomics of the interaction between the user and the device.
Fifty participants between the ages of 45 and 75, with 62% above 60 yrs. old and 26% above 70 yrs. old were observed and interviewed adjusting and using the prototype and IFU. None of the participants had had prior first-hand experience wearing a hearing aid.
​
“This makes me feel a lot better about the possibility of ever losing my hearing!”
Deliverables
A report outlining our user analysis findings was presented to the client and modifications to the design based on our recommendations were made before the final product was introduced to the market.
