Depending on the kind of task and/or material, listenerssometimes need to pay attention to understand communication. The present study aimed toestimate a listener’s amount of effort needed to understand communication by using recognitionscore and response time as a function of signal-to-noise ratio (SNR) and to confirm his/her task dependency for listening effort. Subjects and Methods: Forty-eight young adultswith normal hearing participated in the study. As stimuli, Korean Speech Perception in Noisetest without a question tag and three consecutive digits were used for sentence recognition(or single-task) and arithmetic (or dual-task), respectively. Both tasks were measured in quietand under four SNR (i.e., 0, -4, -8, -12 dB) conditions. Their outcomes were analyzed andcompared in terms of percent correct and response time. Results: Sentence recognitionscores and arithmetic scores decreased as the level of noise increased. Response time forsentence recognition decreased as noise increased, whereas the response time for arithmeticincreased as noise increased. In addition, there was a negative correlation between error percentand response time in the sentence recognition. Conversely, a positive correlation betweenerror percent and response time appeared in the arithmetic test. Conclusions: Listeningeffort showed a different pattern based on the kind of task, single vs. dual, while thedual-task required greater effort from the listener.
