The Food and Drug Administration has approved the marketing of a device that uses acoustic shock waves to boost wound closure in patients with diabetic foot ulcers (DFUs), an especially stubborn and dangerous condition.
However, in the context studied here, although exposure may last for a long period, operators are rarely exposed to high noise levels, apart from cases of acoustic shock. It is important to keep in mind that the purpose of this study has not been to investigate the effect of acoustic shocks, but rather to assess potential auditory fatigue due to the long duration of exposure.
