High frequency range of human hearing

Naturally, the human ears have the sense of what is going on around us. The human ears get the vibrations caused by sound waves in the air.

Simply, the human catches these vibrations in the middle ear, where they are moved into pressure waves. Then, these waves are passed through liquefied into inner ear, where they are converted into signals the brain can infer.

The amount of sound vibrations produced per second is called as frequency and it is calculated in hertz (Hz).

The lower the frequency, the lower the pitch of the sound and typically, the younger you are, the better you hear.

The normal frequency can humans hear by age is around 20 to 20,000 Hz. The normal audible distance for loudness is from zero to 180dB. Beyond 180dB is considered as damaging.

High frequency range of human hearing

When people get older, they are exposed to loud sounds that can damage the ears. In the realm of 50 to 60Hz, it is not too far from the bottom of human hearing range.

The sounds with frequency range of human hearing above the areas of human ears are known as ultrasound and those below are known as infrasound.

The humans are capable of differentiating between 1400 to odd pitches and relatively lower spectrum. The top note of human speech is around 2048 Hz and the lowest note is around 64 Hz.

What is meant by high frequency hearing loss?

One of the most common kinds of hearing loss is caused by aging, which is called as presbycusis. This kind of hearing loss can make difficulty in hearing the high frequency sounds.
