Test your ears [20 Hz - 20 kHz]

The human ear can detect sounds in the frequency range of about 20-20 000Hz (depending on individual gifts, he man), outside these limits human sound perception. Sound with a frequency below 20 Hz is called infrasound, at a frequency higher than 20 kHz the ultrasound. Here you can test how well you hear. Attention !!! then turn down the volume.
