alleryThe human audible frequency range is approximately:
A20 Hz to 20,000 Hz
B0 to 20 Hz
C20,000 Hz to 1 MHz
DUp to 1 Hz only
Answer & Solution
Correct answer: A. 20 Hz to 20,000 Hz
Healthy young humans can hear frequencies from about 20 Hz to 20,000 Hz (20 kHz).
This range narrows with age — higher frequencies are typically the first to go.
Sounds below 20 Hz are infrasonic
above 20 kHz are ultrasonic — both inaudible to humans, though many animals (bats, dogs, elephants) can detect them.
