Abstract [en]

One aim of hearing aid fitting is to ease the patient’s effort in understanding speech, i.e. the listening effort needed to perceive speech in different sound environments. To obtain a good hearing aid fitting, knowledge about the patient’s auditory as well as cognitive abilities seems to be important. However, listening effort is usually not included as a fitting criterion, partly as it is not clear how to measure listening effort objectively.

The Auditory Inference Span Test (AIST) is a dual-task hearing-in-noise test, that combines auditory and memory processing. The basis for the test is that when more cognitive resources are required for understanding speech, less cognitive resources are available for storage and processing of the speech information. In AIST, Hagerman sentences are presented in noise and the subject is required to recall and process the sentence information. Recall ability is tested with different cognitive loads. Button-press responses are recorded and used as an estimate of listening effort. In a pilot study, listeners showed decreasing accuracy with increasing cognitive load and longer reaction time at maximum cognitive load, suggesting that the test may be suited as a clinical test for listening effort.

In an ongoing study, the AIST is being evaluated in relation to other auditory and cognitive measures: baseline audiometry (audiogram) and speech in noise test (Hagerman sentences) as well as text based dual processing and storage test (reading span) and updating (letter memory test), as well as subjective rating of listening effort. Data from this study will be presented.
