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 210 Hz sound like?
210 Hz is a bass frequency. It is a low bass tone – a warm hum similar to the low strings of a cello or bass guitar. Phone speakers reproduce it weakly; headphones work much better.
A 210 Hz sound wave completes 210 cycles every second, so one cycle lasts 4.76 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 1.63 m (5.36 ft) long; in water it stretches to 7.05 m because sound moves about 4.3 times faster there.
Musically, 210 Hz is 19 cents above G♯3 (207.65 Hz) in standard A440 tuning. Doubling it to 420 Hz raises the pitch by one octave; halving it to 105 Hz lowers it by one.
