Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes the analysis of evoked potentials to auditory pair stimuli for estimation of uncomfortable loudness level (UCL), which is utilized for fitting hearing devices,
Efficient feature sections from wavelet coefficients of evoked potentials were explored to find the combination in minimizing the error between UCL by subjective report and UCL estimated by our method.
The results showed that the sections after 100ms at 2nd stimuli and over 4Hz were efficient to estimate UCL.
The obtained minimum error was 2.5dB,this precision is sufficient enough for estimate UCL without subjective report.
