Question

The audible range of sound for an average human being is in the frequency range of:

• A. \(20 \, \text{Hz} - 20 \, \text{kHz}\)
• B. \(10 \, \text{Hz} - 50 \, \text{kHz}\)
• C. \(5 \, \text{Hz} - 10 \, \text{kHz}\)
• D. \(40 \, \text{Hz} - 40 \, \text{kHz}\)

Hint:

Humans can typically hear sounds between 20 Hz and 20 kHz. Frequencies above 20 kHz are considered ultrasonic, while those below 20 Hz are infrasonic.

Answer 1

The Correct Option is A

Step 1: Definition of audible sound.
The audible range of sound for a normal human being typically ranges between 20 Hz and 20 kHz.
Step 2: Analyzing the options.
Option (A):
Correct. The audible frequency range for humans is generally between 20 Hz and 20 kHz.
Option (B):
Incorrect. 50 kHz is beyond the human hearing range.
Option (C):
Incorrect. 5 Hz is too low for human hearing.
Option (D):
Incorrect. 40 kHz is above the audible range.
