20Hz to 20kHz (Human Audio Spectrum)

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.

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.

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!

This is what it sounded like when I got to marshal planes. I guess as the engine increased in airflow air was pushed to vibrate at a faster osculation creating this exact effect. Super cool!
