Abstract：Objective To establish performance-intensity function (P-I) curves for monosyllable and di-syllable words lists and short sentences lists, in an attempt to obtain parameters of normal persons. Method Otologically normal subjects (n=20) were recruited from colleges and universities in Nanjing. Using new man-darin speech test materials including monosyllable and disyllable words lists and short sentences lists created by the Department of Otolaryngology, People’s Hospital of Jiangsu Province, intensity points across a speech recognition range of 20-80%and corresponding speech recognition scores, thresholds, as well as the 20-80%and 50%slopes, were obtained. Logistic regression functions were used to create P-I curves. Results Average speech recognition thresholds for monosyllable and disyllable words lists and short sentences lists were 28.5± 0.5 dB SPL, 24.4±0.5 dB SPL and 26.3±0.7 dB SPL, with average linear slopes over the 20%-80%recogni-tion range at 3.5 ± 0.1%/dB SPL, 6.3 ± 0.5%/dB SPL and 7.2 ± 0.4%/dB SPL, respectively. Conclusions This study has established preliminary normative P-I curves for six monosyllable words lists, eight disyllable words lists and five short sentences lists, which can be used in clinical applications as normal hearing stan-dards.
