Fourier's analysis is a mathematical technique used to break down complex waveforms into their constituent sine waves. It allows us to understand the frequency content of a signal and how different frequencies contribute to its overall shape.
Frequency refers to the number of cycles or vibrations per unit of time. In Fourier's analysis, frequency is used to describe the rate at which different sine waves oscillate.
Place theory in hearing suggests that different pitches are detected by specific locations on the basilar membrane in the inner ear. This concept relates to Fourier's analysis as it involves analyzing the distribution of energy across different frequencies.
Hearing Thresholds: Hearing thresholds refer to the minimum intensity level required for an individual to perceive sound at different frequencies. Understanding these thresholds helps in determining how sensitive our ears are at various frequencies during Fourier's analysis.
