Human Audible Range

Frequency band of roughly 20 Hz to 20,000 Hz perceivable by healthy young human ears.

Core Principles & Analysis

• Sensitivity to high frequencies declines with age, a process called presbycusis.
• Sound below 20 Hz is classed as infrasound and above 20 kHz as ultrasound.
• The 44.1 kHz CD sampling rate captures the full 20 kHz audible bandwidth per the Nyquist theorem.

Specifications & Metrics

• FREQUENCY: 20 Hz – 20,000 Hz
