The correct Answer is:
To determine the frequency range that a normal human being can hear, we can follow these steps: ### Step 1: Understand the concept of sound frequency Sound frequency refers to the number of vibrations or cycles per second of a sound wave, measured in Hertz (Hz). Different frequencies correspond to different pitches of sound. ### Step 2: Identify the ranges of sound Sound can be categorized into different ranges based on frequency: - **Infrasonic Sounds**: Frequencies below 20 Hz (not audible to humans). - **Audible Sounds**: Frequencies between 20 Hz and 20,000 Hz (audible to humans). - **Ultrasonic Sounds**: Frequencies above 20,000 Hz (not audible to humans). ### Step 3: Define the audible range for humans The audible range for a normal human being is defined as the frequency range that can be heard by the average human ear. This range is specifically between 20 Hz and 20,000 Hz. ### Step 4: State the answer Thus, the frequency range that a normal human being can hear is **20 Hz to 20,000 Hz**. ### Final Answer: A normal human being can hear sounds in the frequency range of **20 Hz to 20,000 Hz**. ---

  • PASSAGE-III : The human voice can produce sounds with a frequency between 60 Hz and 1300 Hz. It is interesting to note that a normal human ear can hear sound of frequency between 20 Hz to 20,000 Hz. The sound of frequency greater than 20000 Hz is called ultrasonic and the sound of frequency below 20 Hz is known as infrasonic. A human can produce sound of frequency

    A

    B
    200 Hz
    C
    15 kHz
    D
    20 kHz
