Frequency:The number of sound wave cycles per second. Higher frequencies result in higher-pitched sounds, while lower frequencies produce lower-pitched sounds.
Pitch:How high or low a sound is perceived. It is directly related to the frequency of a sound wave - higher frequencies are associated with higher pitches, and lower frequencies with lower pitches.
Experiment:A scientific method used to test hypotheses and gather data. In this context, experiments can be designed to study how different frequencies affect our perception of pitch in human auditory sensation.
