An electroacoustic device intended for use in a clinical setting to generate tones in the audible range to measure the hearing threshold of a patient by establishing the level at which the patient first becomes aware of the sounds. The device controls tone intensity and frequency either by a computer or manually, and displays/records the patient's responses, typically in the form of an audiogram. It may include a bone vibrator for direct inner-ear stimulation.

A noninvasive device consisting of fixed or adjustable elements (e.g., helmet, frame, board, multi-jointed structure) designed to ensure adequate support, positioning and immobilization of the patient's head, neck, and cervical spine typically during intraoperative procedures (e.g., cervical spine or brain surgery) or diagnostic imaging (e.g., dental x-ray procedures). It is typically mounted on an operating/examination table and allows adjustment of the height and angle of the head. This is a reusable device.
