Purpose: This study compared the speech reception thresholds (SRTs) and test-retest reliability of the smartphone digits-in-noise (DIN) test coupled to various sound-field transducers.

Method: Fifty normal-hearing participants (bilateral pure-tone thresholds 0.5-8kHz

Results: Mean SRTs across earphone and different sound field transducers ranged from -11.3 (SD = 0.8) to -11.7 (SD = 1.2). SRTs across the 4 different loudspeaker transducers and earphones were not significantly different (p >.05) between test and retest sessions.

Conclusion: The smartphone DIN test is reliable and can be conducted using various sound field transducers in a sound booth. To allow home-based testing without earphones, with special application to aided performance for speechin-noise testing, the smartphone DIN test should be evaluated in home environments.
