3 Hz clean pure sine wave BASS TEST TONE frequency

3 Hz sine tone, to test your Subwoofer, Speaker, Headphones. Humans can detect sounds in a frequency range from about 18 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some highfrequency sensitivity as they mature); the upper limit in average adults is often closer to 1517 kHz. If you hear frequencies lower than 18 Hz, you might just be hearing harmonic distortion. If you have any suggestions for future videos, please let me know in the comments below :) Test Tone Playlist Image source Sinus Frequenz von geralt
