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 605 Hz sound like?
605 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 605 Hz sound wave completes 605 cycles every second, so one cycle lasts 1.65 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 56.7 cm (1.86 ft) long; in water it stretches to 2.45 m because sound moves about 4.3 times faster there.
Musically, 605 Hz is 49 cents below D♯5 (622.25 Hz) in standard A440 tuning. Doubling it to 1,210 Hz raises the pitch by one octave; halving it to 302.5 Hz lowers it by one.

Harmonics and octaves
Real instruments playing 605 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) | 605 Hz | D♯5 |
| 2× | 1.21 kHz | D♯6 |
| 3× | 1.815 kHz | A♯6 |
| 4× | 2.42 kHz | D♯7 |
| 5× | 3.025 kHz | F♯7 |
| 6× | 3.63 kHz | A♯7 |
| 7× | 4.235 kHz | C8 |
| 8× | 4.84 kHz | D♯8 |
