Perceived listening effort was assessed for a monaural irregular-rhythm detection task while competing signals were presented to the contralateral ear. When speech was the competing signal; listeners reported greater listening effort compared to either contralateral steady-state noise or no competing signal. Behavioral thresholds for irregular-rhythm detection were unaffected by competing speech; indicating that listeners compensated for this competing signal with effortful listening. These results suggest that perceived listening effort may be associated with suppression of task-irrelevant information; even for conditions where informational masking and competition for linguistic processing resources would not be expected. © 2013 Acoustical Society of America;
