Forty-eight young men, 21 with rather sharp audiometric losses above 2 kiloHertz, were given a standard test of monsyllables in noise. On the average, these 47 men scored 10 fewer words correct per 100 than has been reported for normal controls. Scattergrams of performance vs a variety of pure- tone and speech threshold data, however, showed that no audiometric information could predict performance in noise. It was concluded that the standardized speech-in-noise test itself should be considered as the predictor instead of threshold tests, and that it should be validated against actual job performance.
