Methods and evaluation of physiological measurements with acoustic stimuli —a systematic review

Objective.  The detection of psychological loads, such as stress reactions, is receiving greater attention and social interest, as stress can have long-term effects on health O’Connor, Thayer and Vedhara (2021 Ann. Rev. Psychol.72, 663–688). Acoustic stimuli, especially noise, are investigated as triggeri ng factors. The application of physiological measurements in the detection of psychological loads enables the recording of a further quantitative dimension that goes beyond purely perceptive questionnaires. Thus, unconscious reactions to acoustic stimuli can also be captured. The numerous physiologi cal signals and possible experimental designs with acoustic stimuli may quickly lead to a challenging implementation of the study and an increased difficulty in reproduction or comparison between studies. An unsuitable experimental design or processing of the physiological data may result in conclus ions about psychological loads that are not valid anymore. Approach. The systematic review according to the preferred reporting items for systematic reviews and meta-analysis standard presented here is therefore intended to provide guidance and a basis for further studies in this field. For this pu rpose, studies were identified in which the participants’ short-term physiological responses to acoustic stimuli were investigated in the context of a listening test in a laboratory study. Main Results. A total of 37 studies met these criteria and data items were analysed in terms ...
