440Hz 29.14Hz || Sine Wave Audio Frequency

The frequency of sinusoidal wave going trough entire human audio frequency range spectrum, starting at 20Hz to 20,000Hz. Note that the audible sound range for human frequency is increasing exponentially, the idea was to increase the sound 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).

Note: This frequency of sinusoidal wave has the same volume level measured by acoustic pressure all the time, however human sound perception differs depending on frequency. For lower frequencies that are below 1000Hz, you may need to increase your volume, but do not 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 may 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.
