    G R Lightfoot
    Department of Clinical Engineering, Royal Liverpool University Hospital, UK
    Br J Audiol 34:311-6. 2000
    ..The degree of precision appropriate to each measurement is suggested. A warning is given of the audiological consequences of excessive distortion produced by normally functioning audiometers...

    Department of Clinical Engineering, Royal Liverpool University Hospital, Liverpool, UK
    Int J Audiol 43:276-82. 2004
    ..This was more marked if subjects' eyes were maintained in darkness. It is recommended that no correction be made for order effects but that the calibration of ENG-based systems is adjusted immediately prior to each caloric irrigation...
