This post first appeared on HHTM in June 0f 2011. Before he retired, Dr Martin wrote a monthly column for HHTM. His down to earth posts about clinical topics continue to attract high readership years after publication. Here’s one that reflects the way in which times are changing. Technological help via the Internet for hearing aid wearers is no long an impossibility as it was in 2011 and Dr. Martin’s visionary thinking back then is very much of the moment in 2017. And, when help is needed, it still usually requires hands-on work. Dr. Martin’s call for standardized procedures is particularly apropos as the FDA considers OTC instruments.

Today’s hearing aids, like the tiny computers that they are, have enormous potential. But to realize that potential, a lot of things have to be done just right. For example, the software must be installed properly and patients must be knowledgeable and competent enough to operate their hearing instruments successfully.
When things go wrong with your home computer, there are many sources of technical support to turn to. Help is available on the telephone and on the Internet. Very often the owner has a family member or a friend with some computer expertise.
That’s not true with hearing aids. Patients depend on the office where they purchased the hearing aid for all of their support, training, and encouragement. The amount and quality of training provided vary greatly from practice to practice. However, the less-than-stellar rate of consumer satisfaction with hearing aids suggests that more and better training is needed.
- In other words, as an industry we need to do a better job. But, how do we do that? That’s not an easy question, and there is no simple answer. However, I have two suggestions that I believe would help: Provide more problem-solving resources on the Internet.
- Create a standardized checklist for practitioners to follow when they fit hearing aids on patients.
Hearing aids are unique, and very different from other prosthetics such as eyeglasses. The scope of the services rendered by those who fit and dispense them is also unique. We act as diagnosticians for all levels of hearing function across all generations, from newborns, through pediatrics and adults of working age, to geriatric patients in their final years.
We also recommend and implement every facet of the fitting, as well as teaching our patients and family members how to use the hearing aids optimally and keep them in good working condition. The list of tasks we are expected to perform is long and varied, and includes cleaning ears, selecting gain, counseling patients, and much, much more.
Hearing aids come with another complication that makes fitting them successfully increasingly: the fact that their technology is growing more complex at an ever-increasing rate. Today, manufacturers strive to bring new proprietary software to market several times a year.
Adding to the difficulty for practitioners is the lack of uniformity of the software used by the various manufacturers. Yet another challenge is that the population we serve, primarily geriatric, is becoming older than ever, as average life expectancy increases.
WHAT CAN GO WRONG?
A dozen different things can go wrong with a hearing aid fitting that will make the system unusable. When I discuss this with patients, I like to draw an analogy between hearing aids and a baseball game. In baseball, the batter gets three strikes before he’s out. With hearing aid fittings, patients get only one “strike” before they’re “out.” A single problem, even one that seems minor, can render the system totally non-functioning.
Here are a few of the things that can easily go wrong and make the hearing aids unusable:
- A bad battery
- An improperly inserted aid
- An inappropriate volume setting
- The wrong program selection
- Feedback
- Wax in the sound tube
These are common problems, and every hearing aid office spends a lot of time dealing with them.
PROPOSED: A STANDARD CHECKLIST
To help address the most common problems hearing professionals face, I would like to see the development of a “Seven-Star Checklist” to use in fitting hearing aids. Now, I just made up the “Seven-Star” part. There might be more or fewer items on the list. The number is not important; it’s the concept that matters.
Here’s how it would work. When a practitioner concludes a fitting, he or she consults the checklist, which would be included in the manufacturer’s software. The dispenser goes over the list, item by item, with the patient and, if possible, a family member.
The conversation might go something like this:
“The most common problems people have with hearing aids are well known. We want to make sure you don’t experience them. This checklist is designed to prevent these problems from occurring and to ensure that your hearing aids will continue functioning properly when you take them home. So, let’s go through the list.”
Once all the items have been checked off (insertion and removal of the aid, no feedback, proper volume adjustment, being able to hear and understand a family member at a distance of 10 feet, etc.), the practitioner prints out a document–let’s call it the “Certificate of Initial Quality”–and gives it to the patient.
This certificate, whatever its name, would list several web sites developed by manufacturers to assist patients in using their new hearing aids. One neutral site, perhaps the Better Hearing Institute’s, would act as a clearinghouse for the other web sites.
The specifics of this approach can be determined later. But the key point is this: If, as an industry, we focused on the five or seven or ten basic problems that most often derail hearing aid fittings, we could markedly improve consumer satisfaction and benefit. We would also demonstrate our commitment to providing patients with high-quality care.
A CASE IN POINT
Let’s look at how this approach might work for a particular problem. One of the most common reasons that hearing aids malfunction is that they get plugged up with earwax. The average hearing aid office deals with this problem several times a day. The primary clearinghouse for hearing aid assistance would have a dozen links to You Tube or other web sites that had videos showing how to clean out impacted sound tubes.
The accuracy and usefulness of these “How to…” videos would be reviewed by manufacturers and knowledgeable practitioners so that, as with Wikipedia, the content would be constantly updated and improved. The goal would be to provide instructional material that an average consumer or a family member would be able to understand and follow to fix the problem.
The same concept could be applied to procedures such as changing batteries, adjusting the volume control, and using the telephone with a hearing aid.
IT TAKES COORDINATION
In his book, Outliers, Malcolm Gladwell discusses quality control and how its absence resulted in abysmal quality in certain fields. He specifically talks about the airline industry, the military, and, anesthesiology.
In all these examples, he says, it took an extensive and coordinated effort to improve quality. That would be true with the hearing industry as well. It’s not enough to just talk about quality. We will all have to start practicing it.
That will require answering tough questions, such as:
- What organization could take on the role of coordinating this effort?
- How many items and which ones should be on the basic checklist?
- Who would select them?
- Would manufacturers be open to including a standard industry checklist in their fitting software?
- And, most importantly, how do we incorporate the patient’s point of view into this push for improved quality?

Sounds like a great idea. Let me think more on it. One thing that would really help would be having a universal or at semi-universal fitting software as some are great and others completely non-user friendly. I don’t fit the non-user friendly’s instruments.
Not that I necessarily disagree, but the marketplace should look after that problem, as it has with you. If a GUI for a specific manufacturer or hearing aid is weak and lacks flexibility, you tend to drop it. The real problem is those who are tied to a single manufacturer, particularly if its one that has a limited GUI. Here in Ontario, we are required to have a minimum of 3 manufacturers we can draw from, but most of us have accounts with ALL the manufacturers, and take the time to learn the software. It’s time consuming, but worthwhile.
Robert: Since moisture is the leading cause of hearing aid failures and distortion I certainly would include the benifits of the nightly use of Dry & Store to reduce failures and distortion. You may want to include the statistics from your own study that with the drying system the average repair was every 27.2 months and without use 9.7 months. I do think that a check list is important, our audiologists use this procedure in all of our hearing aid orientations.
