    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...

    Guy R Lightfoot
    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...

    Guy Lightfoot
    Department of Clinical Engineering, Royal Liverpool University Hospital, Prescot Street, Liverpool, England
    Ear Hear 30:54-62. 2009
    ..The aim of this study was to determine whether it is possible to predict a normal outcome of the bithermal caloric test by testing at a single temperature and if so, what criteria are most appropriate to use...
