• A Speech Intelligibility Index (SII) for the sentences in the Cantonese version of the Hearing In Noise Test (CHINT) was derived using conventional procedures described previously in studies such as Studebaker and Sherbecoe [ J. Speech Hear. Res. 34 , 427-438 ( 1991 )] . Two studies were conducted to determine the signal-to-noise ratios and high- and low-pass filtering conditions that should be used and to measure speech intelligibility in these conditions. Normal hearing subjects listened to the sentences presented in speech-spectrum shaped noise. Compared to other English speech assessment materials such as the English Hearing In Noise Test [ Nilsson , J. Acoust. Soc. Am. 95 , 1085-1099 ( 1994 ) ], the frequency importance function of the CHINT suggests that low-frequency information is more important for Cantonese speech understanding. The difference in frequency importance weight in Chinese, compared to English, was attributed to the redundancy of test material, tonal nature of the Cantonese language, or a combination of these factors.
