Prediction of hearing thresholds in children using an automated toy discrimination test.
A previous paper described the development of the prototype of a semi-automated, sensitive and accurate version of the McCormick Toy Discrimination Test. In this report we describe a further development of the hardware, and demonstrate that results obtained from the automated test provide a basis for estimating the mean elevation of pure-tone threshold in the child's better ear. The correlation between speech and pure-tone results is high. The average of the better ear pure-tone thresholds at 0.5, 1 and 4 kHz can be predicted from the word-discrimination threshold obtained with the toy test, with a 95% confidence interval of +/- 11 dB.
