normal range of human ear is​

Answer 1

Answer:

about 20 to 20000 hertz

Answer 2

Answer:

The 'normal' hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a 'normal' audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it's the upper frequencies we lose first.
