The purpose of this investigation is to investigate the behavioral manifestations of listening effort. Quantifying listening effort based on an easy to measure behavioral metric would allow for better understanding of the effort that goes into processing conversational speech. The investigators hypothesize that the behavior modifications required to improve the signal to noise ratio in increasingly complex listening environments significantly deviates from quiet listening environments. Further, the investigators hypothesize that this directly contributes to increased listening effort and reduced ability to accurately monitor content for everyday conversation.
