Storage of audiometric data - online - with a small computer.

For online storage of audiometric measuring data we use an audiometer with serial operating output, a computer (DEC PDP 11/03), and a graphic terminal (DEC VT 55). The data can be controlled at any given time on the display and read like an audiogram. To transmit the data it is mainly only necessary to activate one button on the audiometer in addition. Pure tone and speech audiograms appear on the display in separate diagrams; in addition, beneath the pure tone threshold the results of the suprathreshold tests and the impedance measurements are indicated. For additional observations three lines are left available. If desired, a computer-supported masking aid can be used; independent of this, cross-heard values and applied masking noise intensities are stored. Paper documentations can achieve success as a hardcopy or as a four-coloured plotter print. Statistical groupings are possible without further processing.
