Is Tinnitus Treatable?
After a loud concert, a long week on a loud shop floor, a morning at the shooting range or even a close brush with a noisy child, many of us have briefly experienced ringing, whistling or chirping in our ears.
If you’re regularly experiencing these symptoms, however, you might be suffering from chronic or persistent tinnitus. Some people really suffer from their symptoms, experiencing stress, sleep problems, irritability and even difficulties with their mental health as a result — and unfortunately, a significant majority of people with tinnitus have hearing loss beyond the normal range.
Although there is currently no scientifically validated ‘cure’ for tinnitus, not all hope is lost. There’s plenty of evidence to suggest hearing aids can help relieve this life-changing condition.
How Can I Trust What I Read Online?
When you’re looking for medical information online, it can sometimes be difficult to distinguish fact from convenient fiction.
There is a whole heap of competing websites that give out guidance, and many of them tend to use easy-access information posted on other, similar websites when writing their content.
Unfortunately for readers, this can sometimes produce an effect where the scientific studies that online medical claims are based on are repeatedly watered down until they bear only a passing resemblance to the truth.
Here, we aim to present an accessible overview of three scientific studies into treating tinnitus with hearing aids, as well as links for those looking to do their own research. Hopefully, this will let you form your own conclusions and make a decision about your personal healthcare needs.
What the Science Says:
Study 1: “The Efficacy of Hearing Aids for Emotional and Auditory Tinnitus Issues”
This study was conducted by a Brazilian university, UTP, and published by the International Tinnitus Journal in 2016. Scientists investigated how hearing aid use could help with participants’ auditory and emotional issues. Tinnitus is well-known to cause frustration, sleep issues, concentration difficulties and malaise, so these areas are good targets for research.
Method
The method involved 17 participants, all with tinnitus of varying severity and cause, filling out two medical questionnaires – the Iowa Tinnitus Activities Questionnaire and the Iowa Tinnitus Handicap Questionnaire, first before and then three months after being fitted with hearing aids. Of these 17, 13 were female and four were male. The average age was 57 years old.
Usefully, both questionnaires worked by rating the severity of the disturbance tinnitus causes out of 100, allowing for accuracy above and beyond that of ten-point scales or similar. The two questionnaires measured disturbances to participants’ social, emotional and behavioural wellbeing, hearing, sleep quality and concentration between them.
Results were then analysed statistically.
Findings
Before the fitting of hearing aids, the participants reported that their tinnitus disturbed their concentration by a mean average of 37%, emotional wellbeing by 35% and hearing by 41%.
After hearing aids were fitted, participants gave lower values in all three areas: an average disturbance of 23% for concentration, 26% for emotional wellbeing and 25% for hearing.
The team of scientists’ statistical analysis of these results led them to state that the experiment demonstrated a “significant” improvement from the use of hearing aids to treat tinnitus.
Conclusion
The scientists concluded that “analysis of the results evidences that the use of hearing aids promotes the improvement in the quality of life of patients with tinnitus, ultimately in emotional and auditory aspects.” Bear in mind, however, that this was a very small study, so might not be indicative of the population at large.
Study 2: “Hearing Aids and Tinnitus Therapy: a 25-year Experience”
From South America to Australia, and from 17 participants to 1440 — this experiment was conducted over a quarter of a century by practising otolaryngology physicians in the Royal Victorian Eye and Ear Hospital in Melbourne, Australia, then published in 2008 by the Journal of
Laryngology & Otology.
Method
Between 1980 and 2004, patients attending a tinnitus clinic with hearing loss, again of mixed cause and severity, were assessed on their “tinnitus perception improvement” by asking them to rate their symptoms before and after being fitted with hearing aids. Patients had both one-and-two-sided hearing loss. The experiment switched from using analog to digital hearing aids when they became widely available in 2000.
Findings
Respectively 67% and 69% of patients with unilateral and bilateral hearing loss reported “some improvement” in their tinnitus perception once they were fitted with hearing aids.
Interestingly, there was a “statistically significant” improvement once patients began to receive digital rather than analog hearing aids at the turn of the millennium — which will certainly be of interest if you’re choosing between the two.
Conclusion
The investigation concluded that the “provision of hearing aids in patients with audiometrically demonstrable hearing loss can play a very important part in tinnitus control.”
Study 3: “Tinnitus Treatment and the Effectiveness of Hearing Aids”
Finally, we head to the USA and to a joint study between two American physicians. This study surveyed working professionals and specialists working in the auditory field rather than directly dealing with patients. This method allowed a significant sample size and drew usefully on existing expertise nationwide.
This paper is notable for its sympathetic and detailed introduction describing the life-changing problems encountered by tinnitus sufferers, which by some estimates make up 10-15% of the U.S. population. It also notes how many people never see the doctor about their hearing problems, whether because of the cost or due to the widespread perception that tinnitus isn’t treatable.
The authors are adamant that it is, and certainly have the numbers on their side.
Method
In 2008, 230 professionals responded to an online survey across 44 U.S. states and Canadian provinces. They were working in private practice, hospitals, universities, and the military.
Findings
The survey found that roughly 60% of patients report some relief from their tinnitus symptoms when treated with hearing aids.
Zoomed in, that’s 16.6% reporting minor relief, 21.4% reporting moderate relief and 22.1% reporting major relief. Only very few people reported that hearing aids worsened their tinnitus (1.7%), while 39% of patients could care less either way.
Interestingly, the respondents felt that 20% of their patients weren’t being served by any “existing treatment modalities” at the current time, which shows there’s still plenty of research to be done in the area.
Conclusion
The authors state with dismay that there are nine million people in the U.S. who haven’t sought treatment for tinnitus-accompanied hearing loss, despite it being commonly treatable. Otherwise, they conclude that “in addition to improving communication, hearing aids can also help tinnitus.”
Takeaway Points
- Three studies from around the world, with a variety of sample sizes and methodologies, found promising statistically significant improvements in tinnitus perception when sufferers were treated with hearing aids.
- A large number of people (certainly in the U.S.) don’t seek treatment for tinnitus or hearing loss, despite the multiple treatments available. However, more research would be welcome for the fifth of sufferers whose physicians report a lack of options.
Many people that could benefit from the use of hearing aids wait years before they access treatment — don’t hesitate to ask a medical professional if they could help you. Of course, tinnitus should be treated on a case by case basis, and your doctor will be able to advise on appropriate treatment options for you.
