• The high and low frequency characteristics of clinically used electronystagmography (ENG) machines were evaluated using a "dummy patient" calibration source. About one half of the machines yielded tracings that were either seriously divergent from specifications or that otherwise inaccurately reproduced the calibration wave form. Some of these differences do affect the accuracy and quality of clinical recordings.
