Figure 1
From: In-situ hearing threshold estimation using Gaussian process classification
The figure shows audiograms obtained from two study participants, one with normal hearing (panel (a) through (f)) and one with hearing loss (panel (h) through (l)). The traces in the top row with the “x” markers show the behavioral hearing thresholds at discrete frequencies, at which hearing was assessed during standard audiometry by a certified audiologist in a sound-reduced chamber with standard equipment. The green traces in the top row with the “o” markers show pure tone thresholds of the same patient obtained with a self-guided in-situ testing procedure using hearing aids in a sound-reduced environment. The second row shows the thresholds for the different methods at the same frequencies. The third row shows the difference between the methods. Both methods provided similar results for the hearing thresholds of the patients. The broken red line indicates the zero line or normal hearing.
