title: [Scoring formula research and equivalence evaluation of mandarin quick speech-in-noise test materials in mainland China].
abstract: OBJECTIVE
  To discuss the scoring formula and evaluate the lists equivalence of Mandarin Quick Speech-in-Noise (M-Quick SIN) test materials in mainland China, and for standardizing our research.
  
  
  METHODS
  Double 39 subjects with normal hearing were participated in part one and part two of our experiments, respectively. 20, 18, 15, 13, 10, 8, 5, 3, 0, -2, -5, -7, -10 dB SNR were presented in part one; and 20, 15, 10, 5, 0, -5 dB SNR were presented in part two. The results were analyzed by SPSS 13.0.
  
  
  RESULTS
  SNR-50 was -2.24 dB SNR and "SNR loss = 24.5--correct words" was defined as the scoring formula. All the 13 lists had the e quivalent difficulty.
  
  
  CONCLUSIONS
  Defined "SNR loss = 24.5--correct words" as the scoring formula of M-Quick SIN, and the 13 lists had better difficulty equivalence, which could be used in our further clinical research.
