Human hearing range

Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)

What is the normal hearing range?

A person with normal hearing perceives sounds at frequencies between 20 and 20,000 Hz. Frequencies between 500 and 4000 Hz are most important for speech processing.

How high can humans hear?

For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That's about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz.

What is the range of human hearing in dB?

Most speech sounds range from 30 to 70 decibels, the exact human hearing frequency range that describes mild-to-moderate hearing loss.

Can humans hear 40hz?

40 Hz is a very deep bass tone – the kind of rumbling tone that you feel in your body as much as you hear it. Small speakers, such as laptop speakers or small computer speakers, don't go that low. If you try anyway, you will either hear nothing, or you will hear mostly – or only – distortion.
