Development of an audiometry data processing system

The development was reported of an electronic data processing system of computerized automatic audiometry and of Bekesy audiometry. This system using a microcomputer has the following features: (1) The large amount of data obtained through (a) automatic audiometry, (b) Bekesy audiometry (measurement at fixed or continuous frequency plus test practice, and (c) the Temporal Tone-Decay test can be stored on-line in real time, and are processed and displayed off-line at any time. (2) When retrieved, the output format of these audiometric data is of the same pattern as the conventional audiogram. (3) The output pattern on the CRT graphic display can be hard-copied whenever desired. (4) The system can be operated manually in the same way as the conventional method. (5) The SISI and DL tests can be executed manually and the resultant data keyed into computer storage. And (6) The operation from the data input to the retrieval output is performed interpretively through the CRT display, so that anyone even without special computer or audiological training can operate it at any time.
