Improving the time-efficiency and reliability of the digits-in-noise hearing screening test : a comparison of four procedures

Abstract

Recently, researchers have attempted to increase the time efficiency of the smartphone DIN test by decreasing the number of presentations of the DIN. One suggestion was to use a variable step size based on the correctness of digits identified within the triplet. In contrast, another suggested using a fixed signal-to-noise ratio (SNR) presentation level for all presentations of the DIN test and producing a pass/fail result based on whether a 95% recognition level was reached. This study aimed to compare three novel DIN test procedures as a potential way to improve efficiency with acceptable reliability using smartphone technology.
