Click-evoked wave I amplitude as a function of 1-year L Aeq8760 noise exposure scores was measured using earlobe electrode placement (current data set, circles) or mastoid electrode placement (triangles), for click signals presented at 90 dB nHL. Data from both men (filled symbols) and women (open symbols) are plotted, with no significant associations revealed when the current data were analyzed in combination with the data from Stamper and Johnson. 28 Abbreviation: nHL, normal hearing level.
