Low-powered ultrasound in the inhibition of tinnitus.
An experiment was performed using low-level ultrasound in an attempt to inhibit tinnitus during and after stimulation. The method used a double-blind crossover technique with a placebo. Forty subjects were tested, and they generally reported little or no change in their tinnitus, the results from placebo and ultrasound not being statistically different. It cannot be concluded, therefore, that the ultrasound we were using has any beneficial effect on tinnitus. These results do not confirm the findings of the pilot study using the same ultrasound devices (Carrick et al., 1986).
