Abstract
To meet the need for an objective self-test for hearing screening, a new Dutch speech-in-noise test was developed. Digit triplets were used as speech material. The test was made fully automatic, was controlled by a computer, and can be done by telephone. It measures the speech reception threshold (triplet SRTn) using an adaptive procedure, in about 3 min. Our experiments showed no significant influence of telephone type or listening environment. Measurement errors were within 1 dB, which makes the test accurate. In additional experiments with hearing-impaired subjects (76 ears of 38 listeners), the new test was compared to the existing sentence SRTn test of Plomp and Mimpen, which is considered to be the standard. The correlation between both SRTns was 0.866. As expected, correlations between the triplet SRTn test by telephone and average pure-tone thresholds are somewhat lower: 0.732 for PTA0.5, 1, 2, and 0.770 for PTA0.5, 1, 2,4. When proper SRTn values were chosen for distinguishing between normal-hearing and hearingimpaired subjects, the triplet SRTn test was found to have a sensitivity of 0.91 and a specificity of 0.93.
