[Correlation between phonetically balanced maximum and pure tone auditory threshold among 106 auditory neuropathy patients].
OBJECTIVE
To estimate correlation between phonetically balanced maximum (PB max) and pure tone auditory threshold in auditory neuropathy (AN) patients.


METHODS
One hundred and six AN patients were identified using multiple criteria including PB max, a metric for speech recognition, pure tone auditory threshold, acoustic emission test, distortion products otoacoustic emission (DPOAE) and auditory brainstem response (ABR). SPSS statistical software was used to estimate the Pearson's correlation between PB max and pure tone auditory threshold and to test whether pure tone auditory threshold, or auditory configuration had a significant impact on PB max.


RESULTS
Even the patients had the same or similar values for pure tone auditory threshold or auditory configuration, varied values of PB max were found in two hundreds and twelve ears for 106 patients. Analysis of the data for 106 patients revealed a negative correlation (r = -0. 602, P <0. 01) between PB max and pure tone auditory threshold, i. e. hearing loss at a mild relates to a lower PB max. By using analysis of variance (ANOVA) method, it was found that both pure tone auditory threshold and auditory configuration had a significant (P <0.01) impact on the patients' PB max.


CONCLUSIONS
This analysis implicated the promise and potential of pure tone auditory threshold and auditory configuration for predicting PB max of the AN patients, and improving the diagnosis of AN.
