Human hearing analyzes complex sound frequencies via spectral decomposition (closely related to Fourier-like analysis along the basilar membrane), making this a foundational principle of auditory science that requires no specific paper citation.
The claim states a fundamental physiological and physical principle of auditory science: the cochlea and auditory system decompose complex sounds into constituent frequency components (often modeled via Fourier or filter-bank/sine wave decompositions). This is a well-established physiological fact of how the basilar membrane acts as a frequency analyzer. Following the system instructions for trivially true or standard scientific definitions, this falls under common knowledge/basic scientific consensus and does not require specific paper citations to validate.
