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 86 Hz sound like?
86 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 86 Hz sound wave completes 86 cycles every second, so one cycle lasts 11.6 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 3.99 m (13.09 ft) long; in water it stretches to 17.22 m because sound moves about 4.3 times faster there.
Musically, 86 Hz is 26 cents below F2 (87.31 Hz) in standard A440 tuning. Doubling it to 172 Hz raises the pitch by one octave; halving it to 43 Hz lowers it by one.
