Background An untreated hearing impairment could have a severe influence on the morbidity. The Mini-Audio-Test (MAT) has been developed for early detecting of a relevant hearing loss. This follow-up investigation should determine the sensitivity, specificity, and the predictive values for a minimum-level of detected hearing loss of 25, 30, 35, and 40 dB, both, in one octave-frequency between 0.5 and 4 kHz and the average of hearing loss for these four frequencies. Methods This survey uses data which were collected in 2016 and 2017. 943 patients parted into two groups (aged 50 to 59 years and aged 60 years and more), were investigated using the MAT. Statistical analysis on the sensitivity, specificity, and predictive values in respect were done as proportions together with the 95 %-confidence interval by a logistic regression. Results The sensitivity of the MAT was increasing in both groups of age by increasing the minimum of to be detected hearing loss. The specificity was decreasing as well, but less. The positive predictive values were higher for the older age-group and are decreasing by increasing of the minimum of to be detected hearing loss. In general, the values using the averaged hearing loss are noticeably lower than for the single frequency detecting. The values for the negative predictive values were contrary. Conclusion The results for persons aged 60 years and more are worse than for the younger. Therefore, a first screening on hearing loss starting at the age of 50 years seems to be recommended urgently. Only by this, a sufficient rehabilitation of the hearing loss could be done in time so that the negative consequences of an untreated hearing impairment could be influenced positively.
