title: Learning effect when using the Danish Hagerman sentences (Dantale II) to determine speech reception threshold.
abstract: The objective of the present study was to examine the learning effect found when using the Danish sentence test, Dantale II, in our daily clinical work. Specifically, the aim was to determine the within-visit and the inter-visit learning effects when the Dantale II is presented to aided hearing-impaired listeners who have not previously completed the task. Nineteen subjects participated in the study. The within-visit learning effect after listening to 160 sentences was found to be 3.2 dB, and the inter-visit learning effect was 1.6 dB with an inter-visit period range of 14-43 days. For research evaluation of algorithms or hearing aid settings, where the differences are expected to be small, it is recommended that a pool of test subjects are regularly tested using the Dantale II speech material. Moreover, a limitation of the number of signal processing test conditions is suggested.
