Start with your device volume low. Very low tones may be inaudible on phone or laptop speakers; very high tones can be uncomfortable on headphones.
What does 805 Hz sound like?
805 Hz is a midrange frequency. It is a clear midrange tone, close to where the human ear does most of its work for speech and melody.
A 805 Hz sound wave completes 805 cycles every second, so one cycle lasts 1.24 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 42.6 cm (1.40 ft) long; in water it stretches to 1.84 m because sound moves about 4.3 times faster there.
Musically, 805 Hz is 46 cents above G5 (783.99 Hz) in standard A440 tuning. Doubling it to 1,610 Hz raises the pitch by one octave; halving it to 402.5 Hz lowers it by one.

Harmonics and octaves
Real instruments playing 805 Hz also produce harmonics at whole-number multiples of the fundamental. Their relative strength gives each instrument its timbre.
| Harmonic | Frequency | Nearest note |
|---|---|---|
| 1× (fundamental) | 805 Hz | G5 |
| 2× | 1.61 kHz | G6 |
| 3× | 2.415 kHz | D7 |
| 4× | 3.22 kHz | G7 |
| 5× | 4.025 kHz | B7 |
| 6× | 4.83 kHz | D8 |
| 7× | 5.635 kHz | F8 |
| 8× | 6.44 kHz | G8 |
