GeneralClass 12AllAnswered 27 Mar 2026
Answer
The range 20 Hz to 20,000 Hz (20 kHz) represents the typical human hearing range. Young, healthy ears can detect sounds within this spectrum:
- 20 Hz to 250 Hz: Bass and low-frequency sounds
- 250 Hz to 4 kHz: Mid-range (most speech and music)
- 4 kHz to 20 kHz: High frequencies (treble, consonants, harmonics)
Hearing sensitivity typically decreases with age, particularly at higher frequencies.
