55-year-old Linda arrived for her regular KST adjustment sporting sleek new hearing aids. After a few years of declining hearing, and much nagging from her family, she finally relented and had her hearing tested. Below average hearing bilaterally, with the right side most affected.

During her adjustment, right upper molar came up for the first time. Two weeks later, her dentist informed her the filling in the same molar needed replacing. As he was replacing it, Linda felt the drill reverberating loudly in her head, and reminded herself to switch her hearing aids off for future dental checkups.

For the next few days, Linda complained that everything seemed excessively noisy. Back to the hearing specialist: normal hearing bilaterally, with the right side now testing better than the left. That was 2 months ago, and Linda is now planning to sell her sleek (slightly used) hearing aids on eBay.
