This series of two experiments investigated the auditory fatigue caused by pure tones up to 70 db sensation level and .1 to 10 seconds in duration, and charted the very quick recovery from these relatively mild stimuli. No cumulative fatigue effects were found up to 5 seconds of stimulation, and only a slight cumulative effect between 5 and 10 seconds at the louder levels. The fatigue occasione...
BACKGROUND Although the neural mechanism of chronic fatigue syndrome has been investigated by a number of researchers, it remains poorly understood. METHODS Using functional magnetic resonance imaging, we studied brain responsiveness in 6 male chronic fatigue syndrome patients and in 7 age-matched male healthy volunteers. Responsiveness of auditory cortices to transient, short-lived, noise re...
OBJECTIVE To validate self-reported hearing-related symptoms among personnel exposed to moderately high occupational noise levels at an obstetrics clinic. DESIGN Sensitivity, specificity, and predictive values were calculated for questionnaire items assessing hearing loss, tinnitus, sound sensitivity, poor hearing, difficulty perceiving speech, and sound-induced auditory fatigue. Hearing diso...
BACKGROUND Previous research has demonstrated that trained rescuers have difficulties achieving and maintaining the correct depth and rate of chest compressions during both in and out of hospital cardiopulmonary resuscitation (CPR). Feedback on rate and depth mitigate decline in performance quality but not completely with the residual performance decline attributed to rescuer fatigue. The purpo...
