Question:-

Meena has read somewhere that all sound frequencies cannot be heard by the human ear. what is the hearing range of human ear.

(1) 20Hz -20000Hz

(2) More than 20000Hz

(3) less then 20Hz

(4) 20Hz -25000Hz

Answer:-

Hearing range of human ear is 20 Hz - 20000 Hz.

Answer 2

The correct option is 1. 20Hz - 20000Hz.

EXPLANATION:

• Difference in hearing abilities of different species is due to the varying auditory structures.
• Infants can hear sound frequencies a bit higher than 20000Hz, but gradually, when they grow, they lose sensitivity for some higher frequencies.
• This sensitivity deterioration can occur due to different external factors such as some medical conditions and environmental conditions.
