Stress may serve as an adjunct (challenge) or hindrance (threat) to the learning process. Determining the effect of an individual's response to situational demands in either a real or simulated situation may enable optimisation of the learning environment. Studies of acoustic analysis suggest that mean fundamental frequency and formant frequencies of voice vary with an individual's response during stressful events. This hypothesis is reviewed within the otolaryngology (ORL) simulation environment to assess whether acoustic analysis could be used as a tool to determine participants' stress response and cognitive load in medical simulation. Such an assessment could lead to optimisation of the learning environment.
