17Hz Bass Test

Breaking in my new subs , it's pressuring my cab lol . Nice clean sweeps 👍🏻

Yay now my ears hurt! :)

NICE!!!! Did you know that 17 hertz is four octaves below middle C sharp? C# 0 tuned +005!!!! Having trouble? If you play C sharp 0 on a 431.77 hertz instrument, you should get exactly 17 hertz, but not all instruments go that low.
There are 4 notes in this video:
C# -2: x.25 speed will give you 4.25 hertz. There are two parts to a wave: the crest and the trough. There will be a crest before a trough repeated 4.25 times a second, so 4.25 hertz.
C# -1: x.5 speed gives you 8.5 hertz. Infrasound has a frequency lower than 16 hertz. The sound is so low and the wavelength is so long, your hearing doesn't absorb the sound unless it's loud enough. That's why it's below the human hearing.
C# 0: normal speed gives you 17 hertz. 17 hertz is very hard to hear. Use your earphones!
C# 1: also known as Double bass C sharp, x2 speed gives you 34 hertz. Enjoy the deep bass.

HD GUY STOP TELLING BULLSHIT TO THE PEOPLE !!! THE HUMAN EAR CAN LISTEN FREQUENCIES FROM 20Hz to 20000Hz... even an adult is not able to listen 20Hz...only the children can listen 20Hz.... ONE MORE THING ...If your ears are perfect To listen 20 Hz you should stay 17 meters aways from the source of sound. A wave of 20 Hz need 17 meters to complete the full cicle.
