Abstract:
This contribution aims to create a concept for an experimental soundstimuli recognition measurement. After our auditory system detects asound signal, the brain processes information from the signal before itevaluates it as e.g., noise or speech. Therefore, there is a step ofstimuli recognition before it is categorized into e.g., a language ormusic. This recognition process also involves our working memory. Theproposed study aims to measure the involved processes by usingelectroencephalography and electrodermal activity measurements whilethe participants fulfil tasks that occupy their working memory andsimultaneously get exposed to different psychoacoustically definedsound samples, like e.g. traffic noise, in regards to tonality orsharpness, or quiet. Certain sound characteristics have an emotionalweighing that influence e.g. pleasantness or annoyance of a sound,which can consequently impact our psychophysiological state. Thedifferent psychoacoustic characteristics of the sound samples shallshow the sound recognition response as well as the brain areas that areinvolved in sound sorting decision making. The expected results shallcreate an overview of the consecutive sound processing steps. Such asound processing map shall then be used to assess certain soundcharacteristics for acoustic design or noise protection.
