Please always make sure headphones/speakers are set to a low volume to avoid damage to hearing or equipment.

The Audible Spectrum about 20 Hz - 20 kHz Humans can detect sounds in a frequency range from about 20 Hz - 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 .)
