International ClassA61B 5/12 (20060101)AbstractAudiometric system for monitoring manually-conducted hearing tests and for automatically recording the results of such tests. The system includes a modified audiometer for applying tones to a subject at selected frequencies and amplitudes, and a data interface for converting the control settings of the audiometer to digital data in a format suitable for operating printing apparatus to make a printed record of the audiometric test data in predetermined format. The digital data may also be recorded for subsequent analysis or other use. The data interface provides various operational safeguards which assist the audiometer operator in the desired performance of the audiometric testing procedure. | |
