The ultrasonic cleaner doesn’t work against ultrasonic devices, and ultrasonic cleaners don�t work on magnetic rings, either.
In fact, ultrasonic technology has long been linked to health problems.
But a new report suggests some manufacturers of ear-cleaning devices may be overlooking the dangers of their products.
The findings, published Wednesday in the Journal of Occupational and Environmental Medicine, suggest that ultrasonic cleaning products might not be as safe as advertised.
The study looked at 2,944 people�s health and health-related behavior over six months, looking at whether ear cleaners affected the health of their hearing and how well they listened to music or podcasts.
It found that the ear cleaners had no measurable health effects on the hearing and no impact on the participants� mental health.
But the study also found that people who reported using ultrasonic products tended to report higher levels of stress and fatigue than people who didn�t use ultrasonic-powered cleaners.
A more recent study found that ultrasonics were linked to an increase in heart disease and cancer.
In a statement, the American Academy of Dermatology, the world�s largest dermatological association, said it welcomed the new research but noted that many of the products tested in the study did not contain ultrasonic power.
