Peroperative drill-generated noise levels in ear surgery.
A simple technique for the measuring of sound intensities produced by drilling in ear surgery is presented. In 6 patients the sound level from drilling in the mastoid exceeded 100 dBA. The drilling device should be so designed as to avoid acoustic trauma. Furthermore, a surgical technique should be selected, which minimizes the noise levels and duration of exposure as far as is possible.
