Abstract:
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.

Perception of Sound Waves
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...
Graphical and Analytic Representation of Sinusoids
The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
