Sinusoidal wave going trough entire human audio spectrum, starting at 20Hz and ending at 20kHz. Note that the frequency increases exponentially, the idea was to increase the frequency by constant fraction of currently played frequency rather than by a constant value (which would result in clearly noticeable fast change at lower frequencies and nearly no change at higher frequencies). Enjoy.

Note: This wave has the same volume level measured by acoustic pressure all the time, however human sound perception differs depending on frequency. For lower frequencies (below 1kHz) you might want to increase your volume, but don't forget to lower it later to avoid damage to your hearing.

If you don't hear anything below 40-50Hz even at full volume your audio hardware is probably incapable of playing lowest frequencies. You might want to try to listen on the headphones in such case. Also if you stop hearing sound somewhere between 10kHz - 20kHz - do not increase your volume for safety reasons. Every human hears a bit differently and have different hearing thresholds. Hearing range also changes with age. Younger people can usually hear higher frequencies.

    I heard nothing for 2 minutes. Then I remembered that I'm deaf

    What's so cool is that when the frequency is equal to a multiple of the frame rate, the soundwave appears to freeze

    18kHz is what my ears ring at by the end of day. It doesn't start in the morning but after the office, traffic, shopping, the pitch is there.

    Step1: buy headphones Step 2: test this video Step 3: buy new headphones Step 4: Repeat

    This is an excellent test for us older folks - start the tone then listen how the tones shift from ear to ear as the frequencies get higher. This tells you which ears are sensitve to which frequency. For me, the lower frequencies are equal in each ear, but as the tones get higher, they start to shift from ear to ear. Weird!

    dude my neighbors loved this so much!

    Everybody gangsta until you stop the video but it's still playing.

    The great thing about the low frequencies is that you can feel them
  • @shuyu.
    Why am I getting so excited listening to this while learning sound waves for my physics exam
  • @bruhram
    My speaker was sounding so bad cause it fell in water after doing this it works you're a life saver
