- W2388894654 abstract "Objective To obtain the slope and SRT of the P-I function for Mandarin short sentences in 4-talker babble noise, and evaluate/adjust the homogeneity all sentences individually. Methods Forty-eight Mandarin-speaking people aged at 18 ~ 25 with normal aural/oral communicational abilities were participated in the investigation. Psychometric measures on Mandarin speech intelligibility in babble noise were implemented in -1, -4, -7, -10 dB SNR through 16 lists (20 sentences each) of Mandarin short sentences by a Latin-Square experimental design. Estimation and analysis of P-I functions of all sentences were done by Statistica 7.0. Results Histograms about the thresholds and slopes of P-I functions showed that the SNR50 thresholds were in Guassian distribution(μ ± σ=-6.27 ± 2.04 dB), but the slopes not. Two hundred forty sentences with high homogeneity were chosen according to two criteria: threshold variation was within 2σ; slope below 55%/dB. Conclusion Homogeneity achieved by adjustment of SNR for individual sentence based on psychometric measure would play an important role in development of speech test materials." @default.
