“…The stimuli may be averaged by means of tone bursts (in the frequencies of 250Hz25, 500Hz 13,15,19,[25][26][27][28] , 1000Hz 25,28 , 3000Hz 10 , 5000Hz 15,21 ) or clicks 2,9,11,14,16,17,19,21,22,24 ,29 , which shall be employed at intensities above 75 dBHL. Currently, stimuli above 90 dBHL are used 2,[8][9][10][11][14][15][16]18,19,24,[28][29][30][31] .…”
