Q. Human ear is most sensitive to noise in the frequency range: (December 2022, UGC NET)
1. 100 โ 500 Hz
2. 20-20KHz
3. 13-16 KHz
4. 10-12KHz
Correct Ans: (2)
Explanation: The human ear is most sensitive to sounds in the frequency range of 20 Hz to 20 kHz. This range encompasses the full spectrum of sounds that humans can hear, from the lowest bass notes to the highest treble tones. Within this range, the ear is particularly sensitive to frequencies between 2 kHz and 5 kHz, where many human speech sounds are concentrated, making this range crucial for effective communication.
