A total of 24 students (mean age 21.7 years) were asked to identify the frequency of sinusoidal half-waves. Four different frequencies (f1 = 400, f2 = 600, f3 = 800, f4 = 1000 Hz) and four different types of half-waves were generated by a computer-controlled device. Stimuli were presented binaurally via headphones. The results show that the mean threshold for recognizing different frequencies is 2%-10%. As this low value indicates, the human auditory system exhibits a remarkable ability to process fragments of sinusoidal waves.
