Radun and colleagues investigated the effects of impulsive sound on cognitive performance.  They report that “Exposure to impulsive sound (65 dB LAeq) was compared with quiet sound (35 dB LAeq) and steady-state sound (65 dB LAeq). . . . Compared to quiet sound, impulsive sound caused more annoyance, workload, and lack of energy, raised cortisol concentrations, reduced systolic blood pressure, and decreased accuracy. . . . Compared with steady-state sound, impulsive sound was experienced as more annoying and causing a higher workload and more lack of energy.

Birman and Ferguson increase our understanding of the cognitive effects of listening to music.  They report that their study participants “were randomly assigned to four different groups: silence (no music), classical music, rock, and the final group could choose any genre they liked. The California Verbal Learning Test—Second Edition (CVLT-II) was administered to assess participant’s memory. Anxiety was also assessed before and after the memory test to see whether the music had any effect.
