The commonly stated range of human hearing is 20 Hz to 20 kHz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz. Humans are most sensitive to (i.e. able to discern at lowest intensity) frequencies between 2,000 and 5,000 Hz.
Ear cannot respond to all frequencies in an unbiased manner. Audible range of human being is commonly quoted as from 20 Hz to 20,000 Hz, which in fact will vary with age, health, past exposure to noises, and so forth.Ear also acts like a filter and will favour certain frequencies over the others.udible range of human being is commonly quoted as from 20 Hz to 20,000 Hz, which in fact will vary with age, health, past exposure to noises, and so forth.
