Binaural disparity for tone thresholds at 4 and 6 kHz: demonstration by iterative audiometry and application of an acoustical stress

In 24 subjects hearing levels at 4 and 6 kHz were measured 28 times. The ear providing the largest number of best scores manifests itself mainly during recovery of auditory fatigue. The degree with which it manifests itself differs strongly from one frequency to the other. In at least 40% of the cas...

Summary:In 24 subjects hearing levels at 4 and 6 kHz were measured 28 times. The ear providing the largest number of best scores manifests itself mainly during recovery of auditory fatigue. The degree with which it manifests itself differs strongly from one frequency to the other. In at least 40% of the cases it is not the same ear. In a majority of cases, it is the right one for both frequencies. On the basis of binomial testing, predominance of either ear at 4 kHz is identified in 12 subjects and at 6 kHz in 6 subjects, predominance at both frequencies being present in 3 of them.
