DEVICE: Healing Healthcare Pro (00860002174006)

An electroacoustic device intended to be used for both the evaluation of hearing loss (audiometer function) and the evaluation of hearing aids while worn for optimal amplification [real-ear measurement (REM)]; some types may in addition be used to test hearing aid function when being fitted to the patient. It typically consists of a test box and a control unit that connect to an off-the-shelf computer that runs application software to provide results and graphics (which may be stored in a database). It may be used as an audiometer or real-ear-measurement instrument without the test box.

An electronic instrument used to evaluate the functional condition of the middle ear by changing the air pressure in the external auditory canal to measure and graph the mobility characteristics of the tympanic membrane. It identifies abnormalities in tympanic membrane mobility due to stiffness, flaccidity, or the presence of fluid in the middle ear cavity. The device is also used to measure the acoustic reflex threshold from contractions of the stapedial muscle, to monitor healing of tympanic membrane grafts or stapedectomies, or to monitor follow up treatment for inflammation of the middle ear.
