TABLE II.
Auditory thresholds (in dB HL) and measured crossover frequencies (in Hz) for participants with sloping hearing loss. In addition, bolded thresholds mark potential dead regions as identified by a positive finding with the TEN test using the less conservative criteria described by Moore et al., 2000 (masked threshold at least 10 dB above quiet threshold and at least 10 dB above the level of the masking noise)
