What does 505 Hz sound like?
505 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 505 Hz sound wave completes 505 cycles every second, so one cycle lasts 1.98 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 67.9 cm (2.23 ft) long; in water it stretches to 2.93 m because sound moves about 4.3 times faster there.
Musically, 505 Hz is 39 cents above B4 (493.88 Hz) in standard A440 tuning. Doubling it to 1,010 Hz raises the pitch by one octave; halving it to 252.5 Hz lowers it by one.

| 1× (fundamental) | 505 Hz | B4 |
| 2× | 1.01 kHz | B5 |
| 3× | 1.515 kHz | F♯6 |
| 4× | 2.02 kHz | B6 |
| 5× | 2.525 kHz | D♯7 |
| 6× | 3.03 kHz | F♯7 |
| 7× | 3.535 kHz | A7 |
| 8× | 4.04 kHz | B7 |
